serviceType Protocol used by the service (also called the service type).
Possible values: HTTP, FTP, TCP, UDP, SSL, SSL_BRIDGE, SSL_TCP, DTLS, NNTP, DNS, DHCPRA, ANY, SIP_UDP, SIP_TCP, SIP_SSL, DNS_TCP, RTSP, PUSH, SSL_PUSH, RADIUS, RDP, MYSQL, MSSQL, DIAMETER, SSL_DIAMETER, TFTP, ORACLE, SMPP, SYSLOGTCP, SYSLOGUDP, FIX, SSL_FIX, PROXY, USER_TCP, USER_SSL_TCP, QUIC, IPFIX, LOGSTREAM, MONGO, MONGO_TLS, MQTT, MQTT_TLS, QUIC_BRIDGE, HTTP_QUIC, DOT
IPAddress IPv4 or IPv6 address to assign to the virtual server.
IPPattern IP address pattern, in dotted decimal notation, for identifying packets to be accepted by the virtual server. The IP Mask parameter specifies which part of the destination IP address is matched against the pattern. Mutually exclusive with the IP Address parameter. For example, if the IP pattern assigned to the virtual server is 198.51.100.0 and the IP mask is 255.255.240.0 (a forward mask), the first 20 bits in the destination IP addresses are matched with the first 20 bits in the pattern. The virtual server accepts requests with IP addresses that range from 198.51.96.1 to 198.51.111.254. You can also use a pattern such as 0.0.2.2 and a mask such as 0.0.255.255 (a reverse mask). If a destination IP address matches more than one IP pattern, the pattern with the longest match is selected, and the associated virtual server processes the request. For example, if virtual servers vs1 and vs2 have the same IP pattern, 0.0.100.128, but different IP masks of 0.0.255.255 and 0.0.224.255, a destination IP address of 198.51.100.128 has the longest match with the IP pattern of vs1. If a destination IP address matches two or more virtual servers to the same extent, the request is processed by the virtual server whose port number matches the port number in the request.
IPMask IP mask, in dotted decimal notation, for the IP Pattern parameter. Can have leading or trailing non-zero octets (for example, 255.255.240.0 or 0.0.255.255). Accordingly, the mask specifies whether the first n bits or the last n bits of the destination IP address in a client request are to be matched with the corresponding bits in the IP pattern. The former is called a forward mask. The latter is called a reverse mask.
port Port number for the virtual server.
ipset The list of IPv4/IPv6 addresses bound to ipset would form a part of listening service on the current lb vserver
range Number of IP addresses that the appliance must generate and assign to the virtual server. The virtual server then functions as a network virtual server, accepting traffic on any of the generated IP addresses. The IP addresses are generated automatically, as follows:
- For a range of n, the last octet of the address specified by the IP Address parameter increments n-1 times.
- If the last octet exceeds 255, it rolls over to 0 and the third octet increments by 1. Note: The Range parameter assigns multiple IP addresses to one virtual server. To generate an array of virtual servers, each of which owns only one IP address, use brackets in the IP Address and Name parameters to specify the range. For example: add lb vserver my_vserver[1-3] HTTP 192.0.2.[1-3] 80 Default value: 1 Minimum value: 1 Maximum value: 254
persistenceType Type of persistence for the virtual server. Available settings function as follows:
- SOURCEIP - Connections from the same client IP address belong to the same persistence session.
- COOKIEINSERT - Connections that have the same HTTP Cookie, inserted by a Set-Cookie directive from a server, belong to the same persistence session.
- SSLSESSION - Connections that have the same SSL Session ID belong to the same persistence session.
- CUSTOMSERVERID - Connections with the same server ID form part of the same session. For this persistence type, set the Server ID (CustomServerID) parameter for each service and configure the Rule parameter to identify the server ID in a request.
- RULE - All connections that match a user defined rule belong to the same persistence session.
- URLPASSIVE - Requests that have the same server ID in the URL query belong to the same persistence session. The server ID is the hexadecimal representation of the IP address and port of the service to which the request must be forwarded. This persistence type requires a rule to identify the server ID in the request.
- DESTIP - Connections to the same destination IP address belong to the same persistence session.
- SRCIPDESTIP - Connections that have the same source IP address and destination IP address belong to the same persistence session.
- CALLID - Connections that have the same CALL-ID SIP header belong to the same persistence session.

lbMethod Load balancing method. The available settings function as follows:
- ROUNDROBIN - Distribute requests in rotation, regardless of the load. Weights can be assigned to services to enforce weighted round robin distribution.
- LEASTCONNECTION (default) - Select the service with the fewest connections.
- LEASTRESPONSETIME - Select the service with the lowest average response time.
- LEASTBANDWIDTH - Select the service currently handling the least traffic.
- LEASTPACKETS - Select the service currently serving the lowest number of packets per second.
- CUSTOMLOAD - Base service selection on the SNMP metrics obtained by custom load monitors.
- LRTM - Select the service with the lowest response time. Response times are learned through monitoring probes. This method also takes the number of active connections into account. Also available are a number of hashing methods, in which the appliance extracts a predetermined portion of the request, creates a hash of the portion, and then checks whether any previous requests had the same hash value. If it finds a match, it forwards the request to the service that served those previous requests. Following are the hashing methods:
- URLHASH - Create a hash of the request URL (or part of the URL).
- DOMAINHASH - Create a hash of the domain name in the request (or part of the domain name). The domain name is taken from either the URL or the Host header. If the domain name appears in both locations, the URL is preferred. If the request does not contain a domain name, the load balancing method defaults to LEASTCONNECTION.
- DESTINATIONIPHASH - Create a hash of the destination IP address in the IP header.
- SOURCEIPHASH - Create a hash of the source IP address in the IP header.
- TOKEN - Extract a token from the request, create a hash of the token, and then select the service to which any previous requests with the same token hash value were sent.
- SRCIPDESTIPHASH - Create a hash of the string obtained by concatenating the source IP address and destination IP address in the IP header.
- SRCIPSRCPORTHASH - Create a hash of the source IP address and source port in the IP header.
- CALLIDHASH - Create a hash of the SIP Call-ID header.
- USER_TOKEN - Same as TOKEN LB method but token needs to be provided from an extension.
Possible values: ROUNDROBIN, LEASTCONNECTION, LEASTRESPONSETIME, URLHASH, DOMAINHASH, DESTINATIONIPHASH, SOURCEIPHASH, SRCIPDESTIPHASH, LEASTBANDWIDTH, LEASTPACKETS, TOKEN, SRCIPSRCPORTHASH, LRTM, CALLIDHASH, CUSTOMLOAD, LEASTREQUEST, AUDITLOGHASH, STATICPROXIMITY, USER_TOKEN Default value: LEASTCONNECTION

- Alternatively, you can use single quotation marks to enclose the rule, in which case you do not have to escape the double quotation marks. Default value: “none”
Listenpolicy Expression identifying traffic accepted by the virtual server. Can be either an expression (for example, CLIENT.IP.DST.IN_SUBNET(192.0.2.0/24) or the name of a named expression. In the above example, the virtual server accepts all requests whose destination IP address is in the 192.0.2.0/24 subnet. Default value: “NONE”
Listenpriority Integer specifying the priority of the listen policy. A higher number specifies a lower priority. If a request matches the listen policies of more than one virtual server the virtual server whose listen policy has the highest priority (the lowest priority number) accepts the request. Default value: 101 Minimum value: 0 Maximum value: 101
resRule Expression specifying which part of a server’s response to use for creating rule based persistence sessions (persistence type RULE). Can be either an expression or the name of a named expression. Example: HTTP.RES.HEADER(“setcookie”).VALUE(0).TYPECAST_NVLIST_T(‘=’,’;’).VALUE(“server1”). Default value: “none”

cltTimeout Idle time, in seconds, after which a client connection is terminated. Default value: -1 Maximum value: 31536000
soMethod Type of threshold that, when exceeded, triggers spillover. Available settings function as follows:
- CONNECTION - Spillover occurs when the number of client connections exceeds the threshold.
- DYNAMICCONNECTION - Spillover occurs when the number of client connections at the virtual server exceeds the sum of the maximum client (Max Clients) settings for bound services. Do not specify a spillover threshold for this setting, because the threshold is implied by the Max Clients settings of bound services.
- BANDWIDTH - Spillover occurs when the bandwidth consumed by the virtual server’s incoming and outgoing traffic exceeds the threshold.
- HEALTH - Spillover occurs when the percentage of weights of the services that are UP drops below the threshold. For example, if services svc1, svc2, and svc3 are bound to a virtual server, with weights 1, 2, and 3, and the spillover threshold is 50%, spillover occurs if svc1 and svc3 or svc2 and svc3 transition to DOWN.
- NONE - Spillover does not occur.
Possible values: CONNECTION, DYNAMICCONNECTION, BANDWIDTH, HEALTH, NONE

- If set to PASSIVE on all the virtual servers that share the IP address, the appliance always responds to the ping requests.
- If set to ACTIVE on all the virtual servers that share the IP address, the appliance responds to the ping requests if at least one of the virtual servers is UP. Otherwise, the appliance does not respond.
- If set to ACTIVE on some virtual servers and PASSIVE on the others, the appliance responds if at least one virtual server with the ACTIVE setting is UP. Otherwise, the appliance does not respond. Note: This parameter is available at the virtual server level. A similar parameter, ICMP Response, is available at the IP address level, for IPv4 addresses of type VIP. To set that parameter, use the add ip command in the CLI or the Create IP dialog box in the GUI.
Possible values: PASSIVE, ACTIVE Default value: PASSIVE
RHIstate Route Health Injection (RHI) functionality of the NetSaler appliance for advertising the route of the VIP address associated with the virtual server. When Vserver RHI Level (RHI) parameter is set to VSVR_CNTRLD, the following are different RHI behaviors for the VIP address on the basis of RHIstate (RHI STATE) settings on the virtual servers associated with the VIP address:
- If you set RHI STATE to PASSIVE on all virtual servers, the Citrix ADC always advertises the route for the VIP address.
- If you set RHI STATE to ACTIVE on all virtual servers, the Citrix ADC advertises the route for the VIP address if at least one of the associated virtual servers is in UP state.
- If you set RHI STATE to ACTIVE on some and PASSIVE on others, the Citrix ADC advertises the route for the VIP address if at least one of the associated virtual servers, whose RHI STATE set to ACTIVE, is in UP state.
Possible values: PASSIVE, ACTIVE Default value: PASSIVE
newServiceRequest Number of requests, or percentage of the load on existing services, by which to increase the load on a new service at each interval in slow-start mode. A non-zero value indicates that slow-start is applicable. A zero value indicates that the global RR startup parameter is applied. Changing the value to zero will cause services currently in slow start to take the full traffic as determined by the LB method. Subsequently, any new services added will use the global RR factor. Default value: 0 Minimum value: 0
newServiceRequestUnit Units in which to increment load at each interval in slow-start mode.

Synopsis
unset lb vserver
Example
unset lb vserver lb_vip -backupVServer To unset the backup virtual server for multiple vservers use the following command: unset lb vserver lb_vip[1-3] -backupVServer
set lb vserver
Modifies the specified parameters of a load balancing virtual server.
Synopsis
set lb vserver
Arguments
name Name of the virtual server.
IPAddress IPv4 or IPv6 address to assign to the virtual server.
ipset The list of IPv4/IPv6 addresses bound to ipset would form a part of listening service on the current lb vserver
IPPattern IP address pattern, in dotted decimal notation, for identifying packets to be accepted by the virtual server. The IP Mask parameter specifies which part of the destination IP address is matched against the pattern. Mutually exclusive with the IP Address parameter. For example, if the IP pattern assigned to the virtual server is 198.51.100.0 and the IP mask is 255.255.240.0 (a forward mask), the first 20 bits in the destination IP addresses are matched with the first 20 bits in the pattern. The virtual server accepts requests with IP addresses that range from 198.51.96.1 to 198.51.111.254. You can also use a pattern such as 0.0.2.2 and a mask such as 0.0.255.255 (a reverse mask). If a destination IP address matches more than one IP pattern, the pattern with the longest match is selected, and the associated virtual server processes the request. For example, if virtual servers vs1 and vs2 have the same IP pattern, 0.0.100.128, but different IP masks of 0.0.255.255 and 0.0.224.255, a destination IP address of 198.51.100.128 has the longest match with the IP pattern of vs1. If a destination IP address matches two or more virtual servers to the same extent, the request is processed by the virtual server whose port number matches the port number in the request.
IPMask IP mask, in dotted decimal notation, for the IP Pattern parameter. Can have leading or trailing non-zero octets (for example, 255.255.240.0 or 0.0.255.255). Accordingly, the mask specifies whether the first n bits or the last n bits of the destination IP address in a client request are to be matched with the corresponding bits in the IP pattern. The former is called a forward mask. The latter is called a reverse mask.

lbMethod Load balancing method. The available settings function as follows:
- ROUNDROBIN - Distribute requests in rotation, regardless of the load. Weights can be assigned to services to enforce weighted round robin distribution.
- LEASTCONNECTION (default) - Select the service with the fewest connections.
- LEASTRESPONSETIME - Select the service with the lowest average response time.
- LEASTBANDWIDTH - Select the service currently handling the least traffic.
- LEASTPACKETS - Select the service currently serving the lowest number of packets per second.
- CUSTOMLOAD - Base service selection on the SNMP metrics obtained by custom load monitors.
- LRTM - Select the service with the lowest response time. Response times are learned through monitoring probes. This method also takes the number of active connections into account. Also available are a number of hashing methods, in which the appliance extracts a predetermined portion of the request, creates a hash of the portion, and then checks whether any previous requests had the same hash value. If it finds a match, it forwards the request to the service that served those previous requests. Following are the hashing methods:
- URLHASH - Create a hash of the request URL (or part of the URL).
- DOMAINHASH - Create a hash of the domain name in the request (or part of the domain name). The domain name is taken from either the URL or the Host header. If the domain name appears in both locations, the URL is preferred. If the request does not contain a domain name, the load balancing method defaults to LEASTCONNECTION.
- DESTINATIONIPHASH - Create a hash of the destination IP address in the IP header.
- SOURCEIPHASH - Create a hash of the source IP address in the IP header.
- TOKEN - Extract a token from the request, create a hash of the token, and then select the service to which any previous requests with the same token hash value were sent.
- SRCIPDESTIPHASH - Create a hash of the string obtained by concatenating the source IP address and destination IP address in the IP header.
- SRCIPSRCPORTHASH - Create a hash of the source IP address and source port in the IP header.

- If the expression evaluates to a higher numbered priority, the policy with that priority is evaluated next.
- If the expression evaluates to the priority of the current policy, the policy with the next higher numbered priority is evaluated next.
- If the expression evaluates to a priority number that is numerically higher than the highest numbered priority, policy evaluation ends. An UNDEF event is triggered if:
- The expression is invalid.
- The expression evaluates to a priority number that is numerically lower than the current policy’s priority.
- The expression evaluates to a priority number that is between the current policy’s priority number (say, 30) and the highest priority number (say, 100), but does not match any configured priority number (for example, the expression evaluates to the number 85). This example assumes that the priority number increments by 10 for every successive policy, and therefore a priority number of 85 does not exist in the policy label.
type Bind point to which to bind the policy.
Possible values: REQUEST, RESPONSE, MQTT_JUMBO_REQ
invoke Invoke policies bound to a virtual server or policy label.
labelType Type of policy label to invoke. Applicable only to rewrite, videooptimization and cache policies. Available settings function as follows:

- resvserver - Evaluate the response against the response-based policies bound to the specified virtual server.
- policylabel - invoke the request or response against the specified user-defined policy label.
Possible values: reqvserver, resvserver, policylabel
labelName Name of the virtual server or user-defined policy label to invoke if the policy evaluates to TRUE.

bind lb vserver
order Integer specifying the order of the service. A larger number specifies a lower order. Defines the order of the service relative to the other services in the load balancing vserver’s bindings. Determines the priority given to the service among all the services bound. Minimum value: 1 Maximum value: 8192
Example
bind lb vserver http_vip http_svc To bind a service to multiple vservers use the following command: bind lb vs http_vip[1-3] http_svc To bind multiple services to a vserver use the following command: bind lb vs http_vip http_svc[1-3]
show lb vserver
Displays the statistical data collected for a load balancing virtual server.
Synopsis
show lb vserver [
Arguments
name Name of the virtual server. If no name is provided, statistical data of all configured virtual servers is displayed.
Output
insertVserverIPPort The virtual IP and port header insertion option for the vserver.
vipHeader Name for the inserted header. The default name is vip-header.

port Port number for the virtual server.
ipset The list of IPv4/IPv6 addresses bound to ipset would form a part of listening service on the current lb vserver
range Number of IP addresses that the appliance must generate and assign to the virtual server. The virtual server then functions as a network virtual server, accepting traffic on any of the generated IP addresses. The IP addresses are generated automatically, as follows:
- For a range of n, the last octet of the address specified by the IP Address parameter increments n-1 times.
- If the last octet exceeds 255, it rolls over to 0 and the third octet increments by 1. Note: The Range parameter assigns multiple IP addresses to one virtual server. To generate an array of virtual servers, each of which owns only one IP address, use brackets in the IP Address and Name parameters to specify the range. For example: add lb vserver my_vserver[1-3] HTTP 192.0.2.[1-3] 80

icmpVsrResponse How the Citrix ADC responds to ping requests received for an IP address that is common to one or more virtual servers. Available settings function as follows:
- If set to PASSIVE on all the virtual servers that share the IP address, the appliance always responds to the ping requests.
- If set to ACTIVE on all the virtual servers that share the IP address, the appliance responds to the ping requests if at least one of the virtual servers is UP. Otherwise, the appliance does not respond.
- If set to ACTIVE on some virtual servers and PASSIVE on the others, the appliance responds if at least one virtual server with the ACTIVE setting is UP. Otherwise, the appliance does not respond. Note: This parameter is available at the virtual server level. A similar parameter, ICMP Response, is available at the IP address level, for IPv4 addresses of type VIP. To set that parameter, use the add ip command in the CLI or the Create IP dialog box in the GUI.
RHIstate Route Health Injection (RHI) functionality of the NetSaler appliance for advertising the route of the VIP address associated with the virtual server. When Vserver RHI Level (RHI) parameter is set to VSVR_CNTRLD, the following are different RHI behaviors for the VIP address on the basis of RHIstate (RHI STATE) settings on the virtual servers associated with the VIP address:
- If you set RHI STATE to PASSIVE on all virtual servers, the Citrix ADC always advertises the route for the VIP address.
- If you set RHI STATE to ACTIVE on all virtual servers, the Citrix ADC advertises the route for the VIP address if at least one of the associated virtual servers is in UP state.
- If you set RHI STATE to ACTIVE on some and PASSIVE on others, the Citrix ADC advertises the route for the VIP address if at least one of the associated virtual servers, whose RHI STATE set to ACTIVE, is in UP state.
newServiceRequest Number of requests, or percentage of the load on existing services, by which to increase the load on a new service at each interval in slow-start mode. A non-zero value indicates that slow-start is applicable. A zero value indicates that the global RR startup parameter is applied. Changing the value to zero will cause services currently in slow start to take the full traffic as determined by the LB method. Subsequently, any new services added will use the global RR factor.
newServiceRequestUnit Units in which to increment load at each interval in slow-start mode.
newServiceRequestIncrementInterval Interval, in seconds, between successive increments in the load on a new service or a service whose state has just changed from DOWN to UP. A value of 0 (zero) specifies manual slow start.
