Load Balancing Special Services
5. Define the group metric for the server group. Because SIP load balancing is performed based on
Call-ID, only the minmisses metric is supported to ensure persistency.
>>Real Server Group 100# metric minmiss
6. Define the health check for the group. Configure SIP PING request health check which is
specifically developed for SIP-enabled servers.
>>Real Server Group 100# health sip
7. Configure a virtual server for Layer 4 SIP load balancing.
>> # /cfg/slb/virt 1
>>Virtual Server 1# vip 40.40.40.100
>>Virtual Server 1# virt ena
8. Configure the SIP service 5060 for Virtual Server 1.
>>> # /cfg/slb/virt 1/service 5060
>> # /cfg/slb/virt
9. Enable SIP SLB.
>>Virtual Server 1 sip Service # sip/sip ena
10. Enable DAM.
>>Virtual Server 1 sip Service # direct ena
11. Enable UDP load balancing
12. Increase the timeout for idle sessions.
Note: SIP sessions are quite long and data may be flowing while the signaling path is idle.
Because Alteon resides in the signaling path, Radware recommends increasing the real server
session timeout value to 30 minutes (Default: 10 minutes).
When the call terminates with a BYE command, Alteon releases the session entry immediately.
>> # /cfg/slb/real 1/tmout 30
>> # /cfg/slb/real 2/tmout 30
>> # /cfg/slb/real 3/tmout 30
13. Enable server and client processing at the port level.
>> # /cfg/slb/port 25
>>SLB port 25# client ena
>>SLB port 25# /cfg/slb/port 5
>>SLB port 5# server ena
