Twitter robreiner I'm sure his rambling campaign speech made while Pelosi played with her Botox and dentures behind him pr… /i/web/status/1… miles_commodore It was bizarre. This entry was posted in Cisco Networks, Wireless Networking and tagged Catlayst Switch Commands, Show Switchport Interface on Februby wirednot. It’s the little things, sometimes… I like this command a lot where multiple VLANs are in use. So, the command just scrapes the surface of the actual bigger VLAN paradigm in play for interface, while brings all of the VLAN-specific information out into the open, possibly revealing parameters not obvious through the other commands. Storm-control broadcast level pps 2k 1.5k Now contrast that with the simpler command for the same port: Here’s one instance from a production switch:Īdministrative Trunking Encapsulation: dot1qĪdministrative Native VLAN tagging: enabledĪdministrative private-vlan host-association: noneĪdministrative private-vlan mapping: noneĪdministrative private-vlan trunk native VLAN: noneĪdministrative private-vlan trunk Native VLAN tagging: enabledĪdministrative private-vlan trunk encapsulation: dot1qĪdministrative private-vlan trunk normal VLANs: noneĪdministrative private-vlan trunk associations: noneĪdministrative private-vlan trunk mappings: none (It recently helped me get to the bottom of a VLAN issue involving the murky mystical VLAN 1 on a Catalyst 3650). This gem tells you a lot about an individual interface and is handy as heck when odd things might be afoot with VLANs. But at the same time, I do feel compelled to give a call-out to one command that I’ve come to truly appreciate: The list goes on, and as most of you reading this know there are also variations of the commands listed that get you more granular information- like detailed information per single interface, expanded CDP details, only the last so many log entries, etc.īig deal, right? This is pretty basic stuff, I realize. Show run (how the switch is configured).Show VLAN (VLAN database for the switch).Show mac address-table (L2 addresses of connected devices).
Show CDP neigh/show LLDP neigh (connected network devices).Show interface (status, counters, errors, etc).I won’t be telling you anything here that isn’t already in a slew of Cisco docs, but I am working up to a specific point. I’m talking about after configuration is done, and when you come back to a switch later on for whatever reason to troubleshoot or verify operational parameters. Is there any other specific command or help I may have from your side.When it comes to working with Cisco’s Catalyst switches, there are a handful of commands that get used pretty frequently to tell what’s going on. My most important task is that I have all the list of MACs with me and would like to have All the IPs with that MAC Address along with the Ports connectivity. If its 'dynamic' does it mean that we these ports are getting IPs Dynamically through DHCP or anything else. My main intention is about its types i.e. Also, multiple Mac on one port (as per above output) depicting that we may have Hub connected to that port to which multiple PCs or Printers are connected. What my understanding about this command is that it shows all the Active and Non-Active devices whether PCs etc. +-+-+-+-ġ 2 dynamic ip,ipx,assigned,other GigabitEthernet5/9ġ 0000.aabe.4adb dynamic ip,ipx,assigned,other GigabitEthernet5/9ġ 0019.bbd8.1b7c dynamic ip,ipx,assigned,other GigabitEthernet5/9ġ 0019.bbd8.1b8b dynamic ip,ipx,assigned,other GigabitEthernet5/9 Please find some part of the command output for my switch. I would like to get complete detail for the command above.
