200-301 V1 Part 3: VLANs, STP
Config Lab: L2 EtherChannel 1
EtherChannel takes a big step towards improving STP. With two links between switches, but without using EtherChannel, each instance of STP could use only one of the links blocking the other link. With a layer 2 EtherChannel, STP treats the
Config Lab: RSTP Config 2
LAN switches use many default settings that work without you having to do anything, and oftentimes, you can leave those default settings as-is. However, with Spanning Tree Protocol (STP), and its better cousin Rapid STP (RSTP), you should configure some

Config Lab: Trunking for Only Some VLANs
VLAN trunks between Cisco Catalyst switches support all VLANs known to the switches. As time progresses, each time the switch learns of a new VLAN, the VLAN trunk also allows traffic in the VLAN to use the trunk. Is that
Config Lab: Basic VLANs
Configuring VLANs on access switches may be the most common repetitive configuration task in many networks. So what do you configure when adding new access devices to new VLANs? This lab gives you a chance to remember and exercise those
Config Lab: Trunking Puzzle 1
You can memorize VLAN trunking commands by staring at a table – but you will remember them much better if you try different combinations in sample labs, especially if you try them from the CLI of some gear or simulator.
Config Lab: Data and Voice VLAN 2
Ready to prepare some access switches to support IP phones? This latest config lab sets up the problem for that specific task. The lab shows the common access switch configuration required when you connect a switch port to a phone,
Config Lab: Data and Voice VLANs 1
Creating a VLAN is simple: just configure the vlan number command. However, even in a small network with four switches, like the one used in this next lab, a VLAN config lab can give you a few things to think
