Hi All
We have two 5548UP which are in a vpc. Both of them have two connected FEX, single homed.
ISSU check failed on the secondary switch, while it worked on the primary. The failure is caused by the keepalive port?!?
Any ideas?
First primary then secondary switch.

For ISSU to Proceed, Check the Following Criteria :
1. No Topology change must be active in any STP instance
2. Bridge assurance(BA) should not be active on any port (except MCT)
3. There should not be any Non Edge Designated Forwarding port (except MCT)
4. ISSU criteria must be met on the VPC Peer Switch as well
Following are the statistics on this switch
No Active Topology change Found!
Criteria 1 PASSED !!
No Ports with BA Enabled Found!
Criteria 2 PASSED!!
No Non-Edge Designated Forwarding Ports Found!
Criteria 3 PASSED !!
ISSU Can Proceed! Check Peer Switch.
