we have some network trouble with our main Dell Stack.
Stacked are 4 PowerConnect 6248P, in ring (1->2->3->4->1), all with the latest firmware.
At night we had a lot of Network diconnections with the syslog message:
traputil.c(610) 528463 %% 0/3/3 is transitioned from the Forwarding state to the Blocking state in instance 0
This message is logged 100 times per hour in night.
What is interface 0/3/3?
Hi, Can you check disable spanning tree or make it portfast on that interface and check if it has made any changes?
# spanning-tree disable
# spanning-tree portfast
Hope that helps!
could I, but what kind of interface is it?
I don´t find that interface on switch.
Is it an ethernet Port, XG Port, Port-Channel, ...?
That`s the main question, what kind of interface is 0/3/3?
Hi, I believe it should be gigabit ethernet port, gi0/3/3
if you check # show logging does it show in detailed?
on PowerConnect 6248 there are not such commands. But
#show interfaces switchport,
#interface ethernet 0/3/3
show any interface.
Logging shows the message in my first post:
TRAPMGR: traputil.c(610) 528462 %% 0/3/3 is transitioned from the Forwarding state to the Blocking state in instance 0
That´s what makes us a little nervous. Nobody, not even Dell partners, knows whats that for an interface on PowerConnect 6248.
Last week we spend over 3 hours with Dell partners, but nobody could help us.
Hi, I expected to "show logging" command works. Reference pg 1272 https://dell.to/3MHE60z
hmm... You're right I'm also confused about which port is it. It's hard to correlate which physical port with the above log. (at first, I thought it might be port is 0/g3) I'll try to figure out.
Hi helldunkel, I wasn't able to find how to determine it. Might be some devshell command that might help to figure out it but I'm not sure how to do that kind of I feel stucked. Just thinking loudly. Did you find something with partners?
nope. Nobody knows what Dell makes here.
At the next years we must renew our datacenter infrastructure. I thinks it´s time to use an other switch manufacturer. Blackbox devices at this critical places isn´t really good.
Hi, I saw your post now. Sorry for the inconvenience you've experienced. While I would like to assist you with this, I might have to recommend that you contact the support hotline to check if they can assist you.
