4. Create a group to load balance the SIP proxy servers.
>> # /cfg/slb/group 100
>>Real Server Group 100# add 1
>>Real Server Group 100# add 2
>>Real Server Group 100# add 3
5. Define the group metric for the server group. TCP-based SIP load balancing supports all metrics.
For example, set the metric to minmisses.
>>Real Server Group 100# metric minmiss
6. Define the health check for the group. The health check is TCP for TCP-based SIP load balancing.
>>Real Server Group 100# health tcp
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 1/service 5060 Group 100
9. Configure the SIP TLS service 5061 for Virtual Server 1.
>> # /cfg/slb/virt 1/service 5061/Group 100
10. Enable DAM.
>> # /cfg/slb/adv/direct ena
Note: Distribution of sessions between servers is achieved using the minmisses hash method
and is not always even. Call distribution can be improved by increasing the number of Call ID
bytes that are used as input to the hash function. For example:
>> Virtual Server 1 sip Service# sip/hashlen 16
