SwOS

Hello
we have recently bought few CRS317 and CRS328-24p-4S+, 10G links between both switches are not working but the uplink from CRS317 to CCR1009 works.
Tried updating the software but no luck. Any help will be much appreciated.

Thanks

Hello

I have another CRS328 siwtch that has SwOS 2.7 and 10G works here.
Trying to find the older version but cant find in the software downloads or archives.
where can we download the older swos versions.

Thanks

Just manually change the filename in the URL. If the URL shows 2.8 for instance, just change the 8 to 7.

Not sure if there is a better method, but that’s how I’ve done it in the past and it works fine.

Hello

Not sure what you meant, In the SwOS system and upgrade menu there is not any options for changing parameters.
Only 2 options , Download & upgrade and Upload manually.

Thanks
