Nexus 5548 config sync switch-profile works in only one direction

Heiko Kelling

Hi all,

I use a switch profile to keep the configuration of two Nexus 5548 in sync. That always worked. Now I have the problem that the synchronization only works in one direction. Sync from sw2 is ok, sync from sw1 is not ok. I've already tried a few things, maybe someone can help me.

 

Nexus5548 Chassis ("O2 32X10GE/Modular Universal Platform Supervisor")

kickstart: version 7.3(2)N1(1)
system: version 7.3(2)N1(1)

 

sw1# sh vpc
Legend:
(*) - local vPC is down, forwarding via vPC peer-link

vPC domain id : 1
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status : success
Per-vlan consistency status : success
Type-2 consistency status : success
vPC role : secondary
Number of vPCs configured : 298
Peer Gateway : Enabled
Peer gateway excluded VLANs : -
Dual-active excluded VLANs : -
Graceful Consistency Check : Enabled
Operational Layer3 Peer-router : Disabled
Auto-recovery status : Enabled (timeout = 360 seconds)

 

sw2# sh vpc
Legend:

vPC domain id : 1
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status : success
Per-vlan consistency status : success

sw2 (conf sync is working fine)

sw2# conf sync
sw2(config-sync)# switch-profile Nexus
Switch-Profile started, Profile ID is 1
sw2(config-sync-sp)# interface Ethernet117/1/9
sw2(config-sync-sp-if)# no description
sw2(config-sync-sp-if)# verify
Verification Successful
sw2(config-sync-sp)# comm
Verification successful...
Proceeding to apply configuration. This might take a while depending on amount of configuration in buffer.
Please avoid other configuration changes during this time.
