Matt, I bet with mac-move-notification and some eem magic, it might be possible to get that happening on some switches :)
However as you say, the question is too general to suggest an appropriately detailed response. Pradip, from a 1000 foot view I can only guess these things may be worth initially considering without more detail: Layer 1 could include things like UDLD Layer 2 could include a raft of measures such as STP, various Loop/Root/BPU guard, storm control measures, mac-move notifications Layer 3 could certainly use neighbour/event logging in your routing protocols Layer 3-7 could use IP SLA to probes connectivy/services Certainly an EMS may be helpful - polling devices to track memory/cpu/link utilisation having baselines and thresholds, as well as supporting syslog/snmp traps from network elements that can prompt a network operator to investigate a problem Cheers, Adam On Thu, Jul 29, 2010 at 1:29 PM, Matt Hill <[email protected]> wrote: > Wow... > > What sort of loop?
