Configuring SIP SLB

NOTE

With this command, if the real server has been idling for the <sip-hash-table-idle-time> value or is

not reachable due to health check, then it will be replaced with a new healthy real server on arrival

of new packets to the hash bucket. The replacement algorithm attempts to achieve equal

distribution of hash-buckets among available healthy real servers. The system will continue to assign

idle or failed server hash-buckets to another healthy server until it reaches equilibrium.

NOTE

Setting the idle time to 0 redistributes the hash buckets to include new healthy real servers.

Displaying SIP real server connection rate

Use the show server sip-conn-rate command to display the connectivity rate for a real server.

ServerIronADX(config)# show server sip-conn-rate proxy-server-1

Syntax: show server sip-conn-rate <real-server-name>

Example

Displaying SIP virtual server connection rate

Use the show server sip-hash proxy vs command to display the hash table for a virtual server.

ServerIronADX(config)# show server sip-hash proxy-domain-1

Syntax: show server sip-hash <virtual-server-name>

ServerIronADX# show server sip-conn proxy-server-1

Real Server: proxy-server-1 :

Real Port: sip(BOTH REGISTRAR AND PROXY SERVER):
