Cisco Bug: CSCvv72527 - Port-channel gets added as a SPAN destination in monitor session for EX/FX based LC in EOR
Oct 12, 2020
- Cisco Nexus 9000 Series Switches
Known Affected Releases
Symptom: So basically there is a limitation, FEX and SPAN port-channel destinations are not supported on the Cisco Nexus 9500 platform switches with -EX or -FX line cards. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/93x/system-management/b-cisco-nexus-9000-series-nx-os-system-management-configuration-guide-93x/b-cisco-nexus-9000-series-nx-os-system-management-configuration-guide-93x_chapter_011011.html However, when you configure the interface first with "switchport monitor" and then put it in a channel-group the config is getting imported from the interface to the port-channel and allowing it in the SPAN destination port EX based LC. This needs to be blocked. Conditions: When you have "switchport monitor" configured first in the interface and then add it into the channel-group. The monitor session then allow the port-channel as the destination of SPAN.
