Re: loop-protect

Very useful. Some devices do not forward BPDU's so even with spanning-tree enabled there is a potential for a loop to exist.

Loop-protect uses a different multicast address which regular devices should forward. As soon as a loop-protect enabled port sees this packet it will disable the port preventing a loop.

Re: loop-protect

What would be the sintax for the command to fully protect a network, switch by switch...

Re: loop-protect

Generally speaking, you only want to enable this on your edge ports (not switch to switch links otherwise you may block off entire switches if a loop is detected - still you may want to do this if the other switch does not support loop-protect)

5300(config)# loop-protect

Check the release notes for more information o using this feature as well as BPDU Protection
