Re: Comcast / RCN Issues in Boston

[Andy Grosser]

There was an issue during much of the day on Friday 2/24 due to a code
error on a Harvard Internet2 router at NOX.  It was bounced around 4:35 pm
and everything has been fine since.

weirdness with Extreme

[Andy Grosser]

Has anyone else seen this kind of thing before?

2 Extreme Black Diamond 6804s (ExtremeWare 7.2.0b37) at the core 
(active/standby) start to fight over which of them is master for a
particular VLAN.  They go back and forth for maybe a minute, and for a 
brief period, the master switch seems to fight with itself over which will 
cede master status.  The log messages indicate either high/low port count,
or high/low priority, for that particular vlan.  ESRP then forces access 
switches hanging off the cores to flush their forwarding databases.  All 
activity takes place within a span of just over a minute, then dies.


Extreme doesn't have anything to report yet.  Just wondering if anyone has 
seen behavior like this in an Extreme environment.


Thanks,

Andy
