I have a CRS328 PoE switch [1] running a basic port based VLAN with a trunk port to a router and IP access for switch admin purposes. This works fine with ROS 6.48.6 LTS.
But I tried an upgrade to ROS 7.1.1 and it did not work. I could SSH into the switch and ping any host on the same subnet/vlan but not the router gateway accessed through the trunk port.
Spent hours and lots of RTFM but could not find a solution. Does anyone have insight what is happening here?
It can be many things (one possibility is that configuration converter barfed at something during upgrade) … so why don’t you post current configuration for review?
I spent way too much checking the configuration. It was all still there.
Its not like a router where I had to go and setup BGP from scratch after the major version update.
Should have been straight forward on the switch.
In that case there is little to be gained by installing v7 anyway…
But without showing a config export, there is little that can be done.
