Setting up Cisco EtherChannels – Static, PAgP, and LACP
In this lab I used a Cisco Catalyst WS-C3750G-24TS switch [IOS 12.2(25)SEE3] and a Cisco Catalyst WS-C3560G-24TS switch [IOS 12.2(40)SE]. I also physically connected GigabitEthernet 1/0/17 on the Catalyst 3750G to GigabitEthernet 0/17 on the Catalyst 3560G; I did the … Continue reading
Cisco Port Security with Dynamic MAC Address Learning
In this lab I used a Cisco Catalyst WS-C3560G-24TS switch [IOS Version 12.2(40)SE]. Using Cisco Port Security it is possible to associate a static MAC address to a physical port on a switch. This only allows one host with that … Continue reading
