Last Modified

Products (1)

  • Cisco Nexus 7000 Series Switches

Known Affected Releases

6.2(8)S17

Description (partial)

Symptom:
PVLAN list is not seen in the "show vpc consistency-parameters vpc " CLI after copy r s reload of the switch.

switch-two(config)# show vpc consistency-parameters vpc 1 | grep Pvlan
Pvlan list                  2     -                      (2,3)

Conditions:
1. 
In a VPC setup where VPC legs have private-vlan configuration is up and the consistency list is populated correctly and the VPC is up. The VPC legs could be configured in one of the PVLAN modes namely:
private-vlan host, private-vlan promiscuous, private-vlan trunk promiscuous, private-vlan trunk secondary

vPC status
----------------------------------------------------------------------
id   Port      Status Consistency Reason                  Active vlans
--   ----      ------ ----------- ------                  ------------
1    Po10      up     success     success                    2

switch-two(config)# show vpc consistency-parameters vpc 1 | grep Pvlan
Pvlan list                  2     (2,3)                      (2,3)

2. Do a copy r s reload of the local switch (one of the vpc peers of the vpc peers).

And after copy r s reload, the VPC comes back and is formed correctly. But the consistency list does not show the pvlan list which consists of the PVLAN pairs for the current VPC leg port mode.
