[c-nsp] difference between "WS-X4306" and "WS-X4306-GB"(Cisco 4500 platform) modules

[Martin T]

Hi,

any ideas what is the difference between "WS-X4306" and "WS-X4306-GB"
modules? "sh module" output from WS-C4506 switch:

WS-C4506#sh module 3
Mod Ports Card Type                              Model              Serial No.

WS-C4506#


I checked the "sh platform chassis" and "sh platform hardware"
information plus compared "sh int Gi3/3 capabilities" and "sh int
Gi4/3 capabilities" output, but there seems to be no difference
between "WS-X4306" and "WS-X4306-GB"..
