changed native vlan, now can't access switch

[ChuckHaynes]

Greetings,

Switch A has an ethernet interface trunked (manually set to native vlan 20) and it was communicating with Switch B (also an ethernet interface that is trunked - which was still using the default native vlan 1). During some testing/troubleshooting, I changed the native vlan on Switch B to vlan 20 as well. When doing this, I lost access to Switch B. I can still see it from Switch A if I do a 'sh cdp nei'. Is there any way that I can gain access back to Switch B - without power cycling it?

Thanks

What is the management VLAN in switchB? Please share the cdp neighbor details from switch A.

We got the issue resolved. Sorry for the long delay. It turns out the initial problem started as the result of an IP address conflict. Thanks for the help.
