brocade interface won't talk to cisco interface

unknown

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 ?

unknown

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

Problem solved with your holp. default vlan wasnt being routed added dual-mode and all is well. Thanks for your help. The arp suggestion is what led my to the solution. Not sure of why it was working and then not...Thanks again.
