Hi Folks, Can someone please guide me on the usage of "Spanning-tree GUARD" and UDLD (Uni-directional Link Detection) features in the Catalyst switches? My specific question is would there be a need to use both in a situation, as they seem to serve the same basic purpose ? Or is "Spanning-tree GUARD" feature superior as it checks certain software features such as "Ether-channel" and "trunks" also ? Aziz S.
