Catalyst 2960-L (WS-C2960L-24TS-LL) Web UI unavailable after upgrade

robcowart · ‎02-04-2021

I have a brand new Catalyst 2960-L (WS-C2960L-24TS-LL). After upgrading to the latest IOS and Web UI tar file (c2960l-universalk9-tar.152-7.E3.tar) the Web UI is no longer functioning. It can be reached and I get a basic HTTP login popup, but the page itself never renders. It remains a blank white window. The CLI is still available and works fine.

The upgrade was first completed via the UI, with a subsequent attempt using...

archive download-sw /overwrite /reload tftp://SERVER/c2960l-universalk9-tar.152-7.E3.tar

Neither methods results in a working Web UI.

Does anyone have any insights on how to get the Web UI working again?

This is not the first time we have seen this behaviour in the forum.

The issue is the browser, particularly, the "age".
Try looking for an old browser and see if works.

From the cli, Can you post the output of "sh run"
