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).

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.
