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.
