Symptoms

When configured for bridging all traffic, 5200 platform does not bridge STP BPDUs when in PASSTHRU mode.

Impact

Conditions

This occurs under the following conditions: -- Configure a VLAN group and configure to bridge all traffic. -- Configure STP in PASSTHRU mode.

Workaround

None

Fix Information

The 5200 platform now forwards STP BPDUs across VLAN groups when in PASSTHRU mode.
