Can't do on a trunk port! Set port security 3/4 enable [0c3a.0043.ab32] The specified mac address is optional. Otherwise the switch will use the first mac it encounters. This clears any static cam entries for that port. You can add a mac address to the port: Set port security 2/4 00c8.5643.ab45 To verify: show port 2/4 Set the max number of macs on port: Set port security 2/4 maximum 3 Specify the age (how long it will be secure) Set port security 3/4 age [10-1440 minutes, 0 disab] Clear port security 3/4 [mac|all] To set security violation action: Set port security 3/4 violation [shutdown|restrict Restrict: drops all packets from insecure host But remains active. To set the shutdown time: set port security 3/4 shutdown [10-1440 min, 0 disa] Broadcast suppression (within 1 sec interval) Set port broadcast 3/4 75% <- bandwidth based Set port broadcast 3/4 500 < packet based, 500 p/sec Broadcast-based will filter all broadcasts for remainder of the 1 sec interval. Packet-based will filter ALL packets (including unicasts) beyond threshold for remainder of the 1 sec interval.

Check for ports enabled too. • Check the “set vlan” command for additional stuff like: type, state, mtu, said, bridge, • Do a visual on the switch and look for green lights across the board. • When doing a “set trunk 2/9 on 1,4 isl” instead of 1-1005, you HAVE to do a “clear trunk 2/9”. • When doing a “set logging level all 3 default” Make sure the “default” keyword is there, otherwise that whole command is removed on reload or end console session. .
