Has anyone else noticed that on X695 (and probably VSP7400 as it’s the same hardware), SFPs can be impossible to remove? The same SFP can work with no problem in other switches but in X695, they are often stuck. Hopefully this is a problem with only ...

Hi!Has anyone used the micro-B USB port on the 5520, x465 or x870 for console? Is the serial device in the switch “generic” so any operating system will recognize it or is a special driver needed? From the hardware guide (for 5520):“There is one Micr...

Hi!We have a few X620-10X at a customer’s and they and the SFPs in them get very, very hot. They have ambient temperatures in the 25 C range even if some may be in slightly warmer rooms so nothing really out of the ordinary. Still the fans only indic...

Hi!I’ve come across a way to read the optical receive values in X450e switches, something Extreme has told us won’t work. The usual “show port 47 transceiver information detail” will only show the media type (SX/LX/...), vendor and perhaps some more ...

Hi!I have customers that have ordered the new 5520 (funny name as Avaya/Nortel had a 5520 in the past). They all say that they’d like to know the specs for the smaller siblings 5420 and 5320 as soon as possible. I know they’re not released but perhap...

I'm afraid I don't have a solution, but I'm very curious as to why you run the commands this way. Do you execute the "echo "show vlan" | ssh switch" from a Linux/Mac/*nix station or from the switch itself?

As a side-note, all examples in the user's guide I have seen (in the past) have shown a full mesh topology. That is not necessary and employing a "straight down" structure can significantly reduce complexity and is (!) supported by Extreme:Core1 === ...

In addition to Stephens input, if you see any pause frames whatsoever, disable flow control all together. A host (or worse, a switch!) that is sending pause frames will cause the switches to buffer packets and waste buffer memory. That is never good ...

Hi Sam!We’re sending one of the problematic switches in for analysis. I’m done with mine and my conclusion is that the cages are out of tolerance, probably in at least one batch of switches. We have used Extreme original SFPs and had them stick in th...

Will do! Ping me in a month unless I’ve answered here!

X695 SFP cage problems, will not release SFPs

Micro-USB console on 5520 (and others?), are drivers widely available?

Fan speed in X620-10X not increasing despite high temperature, switch and SFP gets very hot

Showing DDMI optical values in X450e that's not supposed to work!

Specs for the new 5420 and 5320???
