Additional SIP session-specific commands
The following global configuration commands are related to SIP SLB. They will affect all virtual
servers with stateful SIP SLB. The commands will not have any effect on the old stateless SIP SLB.
Stateless SIP SLB will still follow the hash table and ages accordingly.
Configuring the maximum number of SIP sessions
Use the server sip session max-sip-sessions command to configure the maximum entries of SIP
sessions.
ServerIronADX(config)#server sip session max-sip-sessions 1000000
Syntax: [no] server sip session max-sip-sessions sip-sessions
The sip-sessions variable can be from 10 through a maximum of 3,500,000 sessions.
NOTE
This command requires a reload. Removing this configuration using no command will reset the
session to 500,000.
Configuring SIP session age
Use the server sip session session-max-age command to configure the session age in minutes.
ServerIronADX(config)#server sip session session-max-age 50
Syntax: [no] server sip session session-max-age age
The age variable can be from 0 through 60 minutes. The default age is 60 minutes.
Disabling partial SIP support for stateless SIP switching
Use the server sip no-create-forward-l7-session command to configure the ServerIron ADX not to
create forward SIP sessions for the second leg of the call initiation by real servers, if the real server
is bound to a SIP switch-enabled virtual server.
ServerIronADX#server sip no-create-forward-l7-session
Syntax: [no] server sip no-create-forward-l7-session
Clearing SIP sessions
Use the clear server sip session command to clear all SIP sessions load balanced to the specified
real-server by setting the age to the maximum age. This command can only be accessed from the
management processor (MP).
ServerIronADX#clear server sip session rs1
Syntax: clear server sip session real-server
