Wasn't this a bug that was fixed with a software upgrade? Does the 1546 MTU
come back after a wr erase and a reload?

Subject: Cat 3550 MTU

a ways back a poster was talking about an OSPF
Adjacency problem on his Cat 3550 - dbd retrans and
all of that because of MTU size mismatch.

I just got my 3550 and installed it in my home lab
last night and surprise, surprise... what do you think
happened.

Stuck in Exstart. But what I found is that the VLAN
int. had a bizar MTU size so I changed it to 1500 on
the VLAN interface and everything was fine.

Just kind of strange. I bought it second hand from a
guy who passed CCIE and need to check the config to
see why all of the VLAN interfaces have a 1546 MTU??

Maybe delete the vlan.dat??

comments??
