Description (partial)

Symptom:

On 3560 of various models the command "show inventory" sometimes will not display 1000Base-SX SFP or other SFP types. Instead "Not Present" is shown under the description. Also EnitityMIB will not report these SFPs.

This affects different switch models and SFP types, but doesn't occur 100% of the time (i.e. sometimes the SFPs can be seen in the output)

Conditions:

Issue has been reported on various switch models including G series running IOS 12.2(50)SE1 and 12.2(50)SE3. Known affected models:
WS-C3560-48TS
WS-C3560-48PS
WS-C3560G-48PS-S
