brocade interface won't talk to cisco interface

[david_wheeler_e]

ICX6450-48p stack of 6 switches (one uplink port) no longer communicate with cisco layer 3 switch.  It was working but just stopped.  The only thing that changed was removing a port channel from the cisco and a lag from the ruckus (brocade).

Hi Dave,

When you remove the Port channel, the associated ports might get disabled to prevent a potential loop, Pls get this verified.



Thanks

I appreciate the reply but we did in fact check the port status on the cisco and the brocade...all are up...

Hi Dave,

Ok, I believe Cisco L3 is the gateway switch, Do you see any arps learned on it from the 6450 ?

I did a show arp and I dont see the ip for the brocade...
