Opened: May 13, 2014

Severity: 4-Minor

Symptoms

On the 5000 and C2400 platforms, when the DB variable 'qinq.cos' is set to 'inner'; a packets inner priority bits do not determine the CoS mapping when the incoming packet is customer-tagged and the outgoing interface is service-tagged.

Impact

Incorrect egress CoS queue mapping. In this case, all packets are mapped to CoS queue 0.

Conditions

On 5000 and C2400 platforms.

Workaround

None.

Fix Information

On the 5000 and C2400 platforms, when the DB variable 'qinq.cos' is set to 'inner', the packets are now handled as expected.
