Symptoms

If an iRule uses the 'nexthop' command to select a VLAN for a virtual server, TMM may crash.

Impact

Traffic disrupted while TMM restarts.

Conditions

-- Virtual server with SIP profile and iRule that executes a 'nexthop' command -- SIP network traffic occurs

Workaround

Avoid using 'nexthop vlan' in an iRule in a SIP environment.

Fix Information

iRule creation does not cause any TMM core.
