Cisco Nexus Checkpoint feature, does it backup vlan database?

[Khoa Pham]

When you create a checkpoint with Cisco Nexus (7010) , does it also backup vlan database?

If you

1. Create checkpoint

2. Remove 10 vlans

3. Roll back to checkpoint

Will it recover the 10 vlans you removed ?

Thanks

Hello Khoa.

I would suggest you to keep vlan config in running/startup config. That will keep vlans in safe and avoid any unexpected delete/restore issues.

Hi,

Not sure what you mean by keep vlan config in running config ? I thought vlan database is in vlan.dat file ?

Hello

I just created a checkpoint within my nexus lab to see if my svi's will still be there after I rollback to that check and they were there.  I only have have two SVI's and two Port-Channel and they both were there in my running-config.

So my answer will be yes it backs up the vlans and SVI

Hope this helps and if so please don't forget to rate

Hi,

Sorry I meant VLAN not SVI interface. Can you please try this

1. show vlan

2. Create checkpoint

3. Remove 2 vlans (not SVI , by using "no vlan #)

4. Roll back to checkpoint

5. show vlan again

And see if you still have 2 vlans that you removed ?

Thanks

Hi

Just wanted to let you know the following:

Create to new vlans

Created checkpoint

did a no vlan (for both new vlans)

Performed a rollback

After this again my vlan's were back in the running-config like it was before I deleted them.

Hope this helps and again don't forget to rate.

I just want to make one more thing clear

Because this is not an SVI, your 2 VLANs does not show up in running-config , only in "show vlan" command. Correct?

This is what I see when I rollback:

So yes you are correct I had to do the sh vlan brief command to see it.

Hope this helps
