We have around a dozen Catalyst 3560 and 2960 switches in a ring topology. We are considering adding storm control to our trunk ports. Up until now we have only used it on edge ports with default values and without error-disable.
I am proposing that we also add storm control to trunk ports at a lower level and that we error-disable only the redundant links that make up our loops.
storm-control broadcast level 25.00 20.00
storm-control multicast level 2.00 1.00
storm-control action shutdown[only on redundant links]
In a storm all links will restrict broadcast which should help accessing remote switches, but the redundant links should errdisable and block the redundant path. It is important that the action line is not applied to links that are not redundant as we could isolate parts of the network.
Does anyone know of a reason not to use storm control on trunks? Also, I would be interested in views on the level I have suggested (25%).
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
