Retrun erros when clickin interface in Switch->Ports menu with NEC production firmware

For NEC swtich running Production firmware, the interface name of the switch appears as "GBE0/n" (where n is the physical port number). When clicking interface name in Switch->Port menu, SNAC returns error. This won't happen with NEC prototype firmware whose interface name is just a interface number. Probably due to this issue, we cannot specify the port on NEC siwtch in defining policy.
