Ports on this switching module may be oversubscribed, depending on utilization.
For further information on these ports, see the
Ports" section on page
The 48 ports can be configured with any combination of small, form-factor
pluggable (SFP) modules. For a description of SFP modules, see the
SFP Modules" section on page
Problem
Insertion of unsupported SFPs (small form-factor pluggable optics) into
a WS-X4448-GB-LX module can cause undetected communication failures
between the supervisor engine and the corresponding module. Subsequent
insertion or removal of SFPs from the module is not recognized by the system.
This activity can be observed on a Catalyst 4500 series switch using Release
12.1(12c)EW1 or later releases.
Reset the module with the hw-module module reset command.
