I was using a 2948G L3 and it was giving me problems. I was told by someone that I need to upgrade the IOS as the IOS I was using gives problem. I was also told that this model of switch is not a good one
Can somebody enlighten me with more information on this particular model

Its an entry level layer 3 swtich, its been "around the block a while" .
I have used em, with no problem....what particular issue are you running into ?
Which version of the IOS are you using ?

Sorry for the late reply. Was out of the office. Anyway, I was using it to connect all our routers and servers. Do some etherchannel and two BVI's.
Here is my config and the current IOS version

What issues are you having on this switch? Also the software you are running is very old. I suggest that you upgrade to 12.0(18)W5(22b) which has lot of bug fixes compared to 120-7.WX5.15a
http://www.cisco.com/cgi-bin/tablebuild.pl/cat2948g-l3
I suggest that you also read the release notes for any known issues
12-17-2002 01:33 PM
version 12.0(7)WX5(15a) RE - was the first version it was released. You def. need to upgrade to the latest 12.0(18)W5(22b). There are many memory leaks bug and other critical bugs on the version you are running.
