Cisco Bug: CSCtb55858 - No qos rewrite on untrusted port in SXI2
Jan 29, 2017
- Cisco Catalyst 6000 Series Switches
Known Affected Releases
Symptom: With QoS enabled globally, interface may incorrectly behave as trust dscp. - If traffic is ingress untrusted port, dscp may be incorrectly retained on egress. - If traffic is ingress trust cos port, packet may be incorrectly treated as trust dscp, thus modifying COS on egress per the DSCP->COS mapping table. Conditions: - Untrusted interface config and QOS enabled globally. - Trust Cos interface config and QOS enabled globally. - This issue is observed in Cat6500 running 12.2(33)SX train and on Cat7600 running 12.2(33)SR train.
