CCNP SWITCH Lab show commands

Second post of this little series. While I was using my CCNP SWITCH lab for testing many different protocols , I “showed” and saved the output of those protocols as well. Refer to the lab overview of my last post in order to understand those outputs.

I basically saved them as a reference for myself in case I am interested in the information revealed by them. I won’t explain any details of the protocols nor the outputs here. Just many listings. Fly over them and reflect yourself whether you would understand anything. :wink: Here we go:

At first here are the show running-config outputs of all 7 involved Cisco devices for download. Please note that there are some more configuration commands present that are not related to the pcap trace such as port-security, storm-control, dhcp snooping, etc.

And here are the various show commands for many different protocols, dependent on the router/switches I used them in my lab.

Router R1a: show standby brief, show cdp neighbors, show ntp associations, show snmp, show ip sla responder

Note the Root ID Cost of 23 which is 19 + 4 since it has a 100 Mbps link to S1 and then a 1 Gbps link to S2 which is root. Also note that this is a PoE switch with two connected devices.
