Lab – Troubleshooting EtherChannel troubleshoot and correct the configuration errors and document your work. Using your knowledge of EtherChannel and standard testing methods, find and correct the errors. Ensure that all of the EtherChannels use Port Aggregation Protocol (PAgP), and that all hosts are reachable. Note : The switches used are Cisco Catalyst 2960s with Cisco IOS Release 15.0(2) (lanbasek9 image). Other switches and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and output produced might vary from what is shown in the labs. Note : Make sure that the switches have been erased and have no startup configurations. If you are unsure, contact your instructor. Required Resources 3 Switches (Cisco 2960 with Cisco IOS Release 15.0(2) lanbasek9 image or comparable) 2 PCs (Windows 7, Vista, or XP with a terminal emulation program, such as Tera Term) Console cables to configure the Cisco IOS devices via the console ports Ethernet cables as shown in the topology Part 1: Build the Network and Load Device Configurations In Part 1, you will set up the network topology, configure basic settings on the PC hosts, and load configurations on the switches. Step 1: Cable the network as shown in the topology. Step 2: Configure the PC hosts. Step 1: Erase the startup and VLAN configurations and reload the switches. Step 3: Load switch configurations. Load the following configurations into the appropriate switch. All switches have the same passwords. The privileged EXEC password is class . The password for console and vty access is cisco . As all switches are Cisco devices, the network administrator decided to use Cisco’s PAgP on all port channels configured with EtherChannel. Switch S2 is the root bridge for all VLANs in the topology.
