| Bug ID |
Description |
| Headline: GX2A 100GPSM4 steady state flap post 6/4th ite port flap, 1st reload Symptoms: On N9K-C9332D-GX2B, when we flap 100G PSM4 link in a loop multiple times, on some occurrence we will see a steady state flap after 50 secs of link up. After this steady state flap, the link remains stable. Workarounds: NA |
|
| Headline: ENH: link local IPv6 BGP CoPP support Symptoms: IPv6 link local BGP classification on CoPP not hit on GX/GX2 PIDs. LLA IPv6 addressing is defined as an address within prefix FE80::/10. Workarounds: NA |
|
| Headline: Credit Loss Recovery is not triggered for FC interface with no transmit credits. Symptom: A Fibre Channel interface that stays at 0 transmit credits is not recovered by the Credit Loss Recovery agent. Workaround: If the interface has switchport ignore bit-errors configured, then remove it with the no switchport ignore bit-errors interface configuration command. |
|
| Headline: Custom COPP causing transit traffic to be punted to the CPU on Nexus 9300-GX2 Symptoms: When custom-COPP policy contains ACL rules which match on Layer 4 destination or source port, transit traffic also hits the COPP and the packets are copied to CPU. This causes duplication of traffic as CPU also routes the copied packets to the destination. Workarounds: Custom COPP policy using src/dst match mitigates punt for transit traffic. |
There are no resolved bugs listed for this release.
● Default bootup mode is LXC and this release supports only LXC mode.
