WebSW3 (config-if)#spanning-tree guard loop. The other protocol we can use to deal with unidirectional link failures is called UDLD (UniDirectional Link Detection). This protocol is not part of the spanning tree toolkit but it does help us to prevent loops. Simply said UDLD is a layer 2 protocol that works like a keepalive mechanism. WebThe Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails. As the name suggests, STP …

The STP operates at Layer 2 of the Open System Interconnection (OSI) model. By means of bridge protocol data units (BPDUs) that exchange between bridges, the STP elects the ports that eventually forward or block traffic.

WebJul 10, 2012 · My LMS (cisco prime 4.1) reported (through discrepancy reports) that loopguard is enabled on ports with "spanning-tree portfast". Theory states: Loop guard cannot be enabled for ports on which portfast is enabled. Since BPDU guard works on portfast-enabled ports, some restrictions apply to BPDU guard. WebUpon a power-cycle, a broadcast storm took down the network and originated from these two switches. channel-group 1 mode on was configured on all ports. From my research L2 etherchannel links should be configured with only channel-group 1 mode desirable L3 links can be configured w/ channel-group 1 mode on as STP isn't running over them.
