How to check ARP table of Cisco ISE

Hi there,

 

What is the CLI command in Cisco ISE that shows us the ARP table? I run ISE version 2.1, "show arp" and "show ip arp" are unavailable!

 

Thanks!

Sadly it doesn't exist.  the ADE-OS is just a very limited IOS style subset.  To see the arp tables you'd need to install the root application and then get root access to the Linux OS.  This is reserved for TAC people only (unless you recently had a TAC engineer install this on your ISE deployment ... ;-)

 

The only other way around this would be to run a TCPdump on your ISE node and then filter on ARP replies.  That might give you a hint.

Hello Anas-

 

Unfortunately, it appears that a command to check the ARP table in ISE does not exist. Here is the link for the latest ISE CLI Guide that you can reference for all of the available CLI commands:
