I have IOS Version 15.2(4)S4 on my router, and "show control-plane host open-ports" does not work, is there any other command to generate such output? the "show tcp brief" and "show ip sockets" are not that good!

IOS Version: 7200 Software (C7200-ADVIPSERVICESK9-M), Version 15.2(4)S4, RELEASE SOFTWARE (fc2)

  • show tcp-small-servers and show udp-small-servers ? Nov 30, 2015 at 21:30

This is not exactly the same but may help, as it shows the far end peer address. Original command did not. But if you use "bgp listen", you then lose the foreign address! Interesting question for an exam maybe.

R5#show tcp brief all
TCB       Local Address               Foreign Address             (state)
6792B388  *.179             *                   LISTEN

For UDP you can use

Router# show udp

and if you want to see detail of a particular socket then

Router# show socket <PID> detail

I don't know which router you use, but on IOS 15, I only know the "show control-plane host open-ports" command, so there is no equivalent to that, as far as I know.
