So tonight I’m working on stacking a set of switch’s I’ve never stacked before. 2x C2960X switches. I’ve done plenty of the normal 3850/9300 stacks with the stack power and stack rings so this one should be pretty much the same.
Pre-requisites for any stacking.
- Backup Backup Backup!
- Ensure IOS versions are the same
- Have your stack modules
- Have the correct stack cables
Now the switch I’m adding has been used previously so first things first.
write erase
Yes
reload
Waiting on the jet engines to slow down so I can confidently grab a cup of joe for the next parts. Also hunt down whoever took my screw driver!
Also need to upgrade the IOS to the latest gold release so another cup of coffee because SCP on the 2960X see below.
So SCP is apparently a bad idea it died before it finished, not sure if pull would be any better I’ll have to check at a later date, but pulling from http might be the best bet in the future if the software allows it.
So began my nightmare. Stack versions were different, expected. Ran the command to sync versions and instead of going to the latest .bin version it synced the master’s installed IOS and pushed it to the other switch.
FWIW – you can install stack modules hot. You can stack the switches hot as well, the new switch is going to reboot through.
No problem right. Big problem. It no longer liked the uplink SFP and I had to drive back into work to swap SFP’s and get it back up. I hate vendor SFP lock-ins. I especially when a older IOS does not recognize a newer Vendor SFP. Nobody wins.
After that I was able to see that I’m on an older IOS (A future thing to do).
