2810 11.48 firmware, unable to access after applied

[MikeMay]

I having some trouble figuring out why after I applied 11.48 to one of my 2810, I was unable able to access it. the switch became isolated.

any help would be great, here is the config of the 2810, as well as the config for the 5400 that is it plugged into. From looking at the logs I am thinking that spanning-tree blocked the trunk port, but I cant see why.

i had the same problem, ones it work after i reset the switch and applied the saved config file, but only for a few minutes.

i solved the problem, with the old firmware.

=> reset

=> simple setup with IP address

=> downgrade with firmware N.11.25.swi

=> deploy old config file

work again :-)

Good luke

Hi Mike

Please call support. This looks like a bug which should be fixed - but the only way to get that done is making a support case.
