Hi all,
On a couple of C9500 40x in VSS I need to replace the 10Gb VSL links with 40Gb links. So I need to go from here:
stackwise-virtual
domain 255
interface TenGigabitEthernet1/0/39
stackwise-virtual link 1
!
interface TenGigabitEthernet1/0/40

Hi. On a big industrial plant we've replaced an old HP switch with a brand new couple of C2960x switches in stack configuration and ever since then, every 6/8 hours or so, the two fiber optics links of switch #2 go down at once. These are connected t...
Hi all, we got a weird problem with a couple of IE5000 switches in horizontal stack configuration. If one and only one of the two members is reloaded, the configuration under a couple of ports is completely lost on reloading, all configuration lines ...
Hi all,note that this is not a real life scenario, I'm just tinkering with my home lab. SWA_C2950_24P#show interfaces trunkPort Mode Encapsulation Status Native vlanFa0/11 on 802.1q trunking 1Fa0/12 on 802.1q trunking 1Fa0/21 on 802.1q trunking 1Fa0/...
Hey all. I'm trying to understand how EIGRP works regarding the best path selection and I can't figure out why it uses the lowest bandwidth in the path from A to B: according to the formula, the highest the bandwidth, the highest the metric. I'd expe...
Hi. What if I use different VSL link IDs? Would creating an additional links set, and then removing the existing links, minimize downtime?

By sheer chance. Last night out of the blue the fiber link of that specific PLC went down, and with it both fiber uplinks on the switch as usual. So, suspecting an issue on that specific PLC, I kept it disconnected, and it's been two days without iss...
SOLVED. This is mental. There was a PLC connected to a fiber optic port on stack switch ONE that somehow managed to disrupt the functionality of the rx side of the optical controller on stack switch TWO, and that for some reason never bothered the pr...
I have disabled the auto recovery, but errdisable itself does not detect anything. It never did.
It just happened again after roughly 8 hours of uptime, both links went down at the same time:
