Hi

I have a MX7000 blade solution with two MX9116N switches running in a VLT domain.

The issue I have is when we reboot the one of the switches its partner seems to think there is an issue and brings down its edge ports -- I have no idea why this is happening.

When checking the configurations, I can see that for some reason whoever configured the switches didn't enable spanning-tree on the switches.  Its configured globally but set to disabled.  So I am making an assumption that this is the reason for it.

This is the spanning tree configuration on both switches (the config is the same on both switches)

spanning-tree mode rstpspanning-tree rstp priority 61440spanning-tree disable

My questions is can I safely enable spanning tree globally and then apply stp to the port-channels without causing any downtime to those port-channels, or will spanning tree put them into blocking mode before getting to forwarding mode?

To confirm this would be the command I would add to the port-channels:

spanning-tree port type edge

Thank you in advance and any help/advice is appreciated.
