Use "set port host" slot/port - port , such as 2/1-48 . The 2948G is a catos box.

Hello Glen,

in the attached sh ver:

System image file is "bootflash:cat2948g-in-mz.120-25.W5.27.bin"

this is an IOS box, isn't it?

Hope to help

In one of cisco's smarter marketing moves they made a 2948G-L3 and 2948G layer 2 box which was based on the L2 cat 4000 box so you have basically have one or the other , the user would have to tell us what exactly he has. The L2 box actually runs Cat 4000 code. I went by the notion it said 2948G and not 2948G-L3 .

Hello Glen,

thanks

the scenario is the same as a C6500 in Hybrid mode there are actually two "devices" in the same box.

Best Regards

Giuseppe
