Default Port and VLAN Configuration/Behavior on Cisco IOS switches

Wednesday, January 1st, 2014

In this short lab, I use two Cisco Catalyst 3550 switches [IOS 12.2(44)SE6] to demonstrate the default port and VLAN behavior on a Cisco switch running IOS. Below is the network diagram for this lab. (more…)

Cisco Catalyst C4003

Cisco Catalyst C4003

Some of you may have an old Cisco Catalyst switch laying around that you may want to put to use. CatOS is the old Cisco operating system for Catalyst switches that predates IOS; it can still be found on some of the old Catalyst switches which are now End of Life (EOL). In this lab I connect a Cisco Catalyst 3548-XL (Model WS-C3548-XL-EN) [IOS 12.0(5)WC13] with a Cisco Catalyst 4003 chassis (Model WS-C4003) [CatOS 5.5(20)] to demonstrate basic configuration and switching between the two. Gratuitous ARP is also discussed and demonstrated in this lab. The setup is as shown in the below lab diagram. (more…)

Setting up Cisco EtherChannels – Static, PAgP, and LACP

Thursday, June 2nd, 2011

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 same for GigabitEthernet 1/0/18 and GigabitEthernet 0/18 respectively. At this point I have two GigabitEthernet connections between the switches. (more…)
