Symptoms

Transparent/translucent Vlangroup may have its MAC address set to 02:00:00:00:00 on either the first configuration load after an upgrade or on a manual mcpd db clear/reload.

Impact

Vlangroup MAC address is incorrect and can adversely affect traffic transversing the vlangroup.

Conditions

Transparent/Translucent vlangroup configured. Upgrade to later version (11.3.0 through 12.1.0) or manually delete mcpd DB binary.

Workaround

Reload configuration or alter vlangroup configuration: e.g: set back and forth between transparency modes.

Fix Information

Vlangroups now correctly establish MAC addresses on first configuration load.
