Nexus 5K VPC saving config

wwwillster07
Beginner
Beginner

We have a Nexus 5K setup as a vPC pair.   I can log into the "primary" do a config update and copy run start saves the config.

 

If I log into the Secondary and make a config change, doing a copy run start results in:

 

Sec# copy run start
[########################################] 100%
Configuration update aborted: request was aborted

 

My secondary is 192.168.203.4 and here's the relevant vpc config:

 

vpc domain 10
role priority 65535
peer-keepalive destination 192.168.203.3
delay restore 150

interface port-channel10
description VPC Peer-Link to NEX5KPRI
switchport
switchport mode trunk
no lacp suspend-individual
spanning-tree port type network
no snmp trap link-status
vpc peer-link

 

 

 

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

vPC domain id : 10
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 : 212
Peer Gateway : Disabled
Dual-active excluded VLANs : -
Graceful Consistency Check : Enabled
Auto-recovery status : Enabled (timeout = 240 seconds)

vPC Peer-link status
---------------------------------------------------------------------
id Port Status Active vlans
-- ---- ------ --------------------------------------------------
1 Po10 up  xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

 

 

It's an inherited system

 

To this point when I've had to make a config change I just made the appropriate change on both.  Which I still don't actually have a problem doing, but what concerns me is the number of updates done to the secondary without the config being saved..

 

Not a whole lot of experience with the NX-OS so any help is appreciated.

 

Thanks@

Hi,

Even with having a vPC between the 2 switches and making one primary and the other secondary, you still have to save the config manually on each switch. Also, based on that output, you may be hitting this bug:

I think you're right.

 

So my option here is reload the switch and lose my latest changes, and re-apply them after?  Then try saving the config again?

You can try that, and see if it helps. If it doesn't you would have to upgrade to a different version of Nexus-OS.

Also, you should open a ticket with TAC on this in case they have more info regarding this issue.

I agree with Reza that you might hitting to a bug but do you have any relevant logs in the log file?
