Cisco Bug: CSCvt53089 - Blade switch MAC entry absent for port channels connected to FI in End-Host mode with CDP enabled
Apr 16, 2020
- Cisco Nexus 9000 Series Switches
Known Affected Releases
Symptom: If a Cisco UCS fabric interconnect is deployed in the end host mode and is a peer to a Cisco ACI ToR switch, and CDP is enabled without LLDP, Blade switch MAC address move tracking is not feasible because CDP does not advertise the peer's MAC address. The blade switch MAC address entry for the fabric interconnect port MAC addresses is not seen in the output of the "show system internal epmc bladeswitch_mac all" command. Conditions: This issue is observed when a Cisco UCS fabric interconnect is deployed in the end host mode and is a peer to a Cisco ACI ToR switch, and CDP is enabled without LLDP.
