Configuring SIP SLB
1
Configuring the maximum number 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 2,000,000 sessions.
NOTE
This command requires a reload. Removing this configuration using no command will reset the
session to 500,000.
Configuring SIP session age
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
ServerIronADX# server sip no-create-forward-l7-session
Syntax: [no] server sip no-create-forward-l7-session
This command does not 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.
Clearing SIP sessions
ServerIronADX# clear server sip session rs1
Syntax: clear server sip session <real-server>
This command clears all SIP sessions load balanced to <real-server> by setting up the age to the
maximum age. This command can only be accessed from the management processor (MP).
Show commands for displaying SIP sessions
NOTE
The show sip session command does not count SIP sessions. Use the show sip server command to
display SIP-related real server information.
