Issue the command to verify trunk settings. Record the command used in the space provided below. f. Issue the command to verify that the port channels are functioning. Record the command used in the space provided below. Step 4: Verify EtherChannel and Connectivity. a. Use the show interfaces etherchannel command to verify full functionality of the port channels. b. Verify connectivity of the management VLAN. Can S1 ping S2? Yes Can S1 ping S3? Yes Can S2 ping S3? Yes c. Verify connectivity of PCs. Can PC-A ping PC-C? Yes If EtherChannels are not fully functional, connectivity between switches does not exist, or connectivity between hosts does not exist. Troubleshoot to resolve any remaining issues. Note : It may be necessary to disable the PC firewall for pings between the PCs to succeed. © 2013 Cisco and/or its affiliates. All rights reserved.
