Severity: 3-Major

Symptoms

F5 recommends using transparent behavior in high availability (HA) configuration with L2 wire transparent vlan-group. With earlier releases, this was not easily accomplished and required physically moving cables to achieve the functionality. In this release, the functionality is provided.

Impact

These settings improve L2 wire behavior for HA configurations. In previous releases, the workaround is to configure internal and external trunks on the BIG-IP system, with each trunk containing interface members connecting to switch (or switch-pair implementing vPC/mLAG), and then define virtual wire with the two trunks as members. However, this workaround requires you to move cables, which makes the insertion of BIG-IP system not L2 transparent.

Conditions

Always for HA (Active-Standby L2 wire setup).

Workaround

None.

Fix Information

This release provides ether-level multicast transparency for L2 wire SSL Orchestrator configurations, which is managed by the following sys db var: -- Use this db variable to enable the functionality: l2.virtualwire.multicast.bridging default enable -- Use this db variable to keep make the standby silent: l2.virtualwire.standby.bridging default disable -- Use this db variable to collect statistics on the traffic: [l2.virtualwire.multicast.stats] default=enable enable collect multicast statistic

Behavior Change
