4948 or 4948E based on Show outputs

Hi Guys,

I have 4948 switch but i am unaable to determine its 4948E or Just 4948 as there is some confusion between BOQ and actual delivered material. In Boq its mentioned 4948E but as per switch show commands output its looks like just 4948.

I need to run EVN features on it but it supports only on 4948E and 4900M switch but not on just 4948

please look at the below show outputs.

In addition is this image is fine to support EVN feature as Cisco feature tool is still not update for 4500 switch.

4948 or 4948E based on Show outputs


Judging from the outputs posted my view is that your box is NOT Cat4948E switch. For that type the switch should be identified as WS-C4948E model. In the "sh ver" output you should see WS-4948E (MPC8548) ... Also the PSU units for the 4948E type are identified as PWR-C49E-300AC-R. Also the IOS file at your version should read cat4500e-entservices-mz.150-2.SG4.bin for the 4948E unit and the minimum ROMMON release should be  12.2(44r)SG8 while your is 12.2(31r)SGA2.

Finally I do hope you are referring to WS-4948E box and NOT WS-4948-E which would be a different story.

Best regards,
