[c-nsp] Nexus 56xx switch-profile problem after upgrade

[Christophe Fillot]

Hello,

We have upgraded a pair of Nexus 5672 from 7.2(1)N1(1) to 7.3(0)N1(1).
We now have a switch-profile commit error related to spanning-tree.

In the running configuration (sh run) we have:

  spanning-tree pseudo-information
    vlan 1-3967, 4048-4093 root priority 0

In the switch-profile configuration (sh run switch-profile) we have:

  spanning-tree pseudo-information
    vlan 1-3967, 4050-4093 root priority 0

The problem is that VLANs 4048-4049 now seem to be reserved and the
parser does not accept them:

n5k-bf-b(config-sync-sp)# spanning-tree pseudo-information
n5k-bf-b(config-sync-sp-pseudo)# no vlan ?
  <1-3967,4050-4093>  Vlan range, Example: 1,3-5,7,9-11

n5k-bf-b(config-sync-sp-pseudo)# no vlan 4048 root priority 0
                                         ^
invalid vlans (reserved values) at '^' marker.

It won't accept a commit even with an empty buffer:

Status: Verify Failure
Error(s):
Following commands failed parsing: If the error is 'Command Parsing
Failed', please check if some conditional feature(s) needs to be enabled
vlan 4048 root priority 0 (Command Parsing Failed)
vlan 4049 root priority 0 (Command Parsing Failed)

I cannot modify the local configuration (conf t) because of the
Exclusive Mutual error message.

Is there a way to fix this without breaking anything ?

Thanks,

Christophe
