ARP address for the management IP

When I run the command show ip arp | i a.b.c.d, where a.b.c.d is the management ip of the vcmp system (7200v in this case), it gives me a mac address which I am not able to find on the device. It is vertainly not the base mac address of the device which can be seen from Device management -> Devices -> properties. I tried running few commands on cli but no joy. Please suggest.

Use the linux command with the user "root" or with a user account which has access to advance shell

ip a | grep -A 2 mgmt

link/ether shows the MAC address of the mgmt port.

Or you can try this one

show sys mac-address | grep -i mgmt

To get the management MAC use the following command on tmsh:

tmsh show sys hardware | grep 'Base MAC'

Also the VIPRION chassis has a virtual interface behind the physical management interfaces of each blade.

On BASH try running the following to get management interface details:

ip addr show mgmt

It still does not give the mac-address which I got after running ARP of the management ip.

This is likely because you're getting the MAC of the linux mgmt interface.
Try from bash: ifconfig mgmt or ifconfig eth0

You should see the same MAC you see in the upstream L3 device ARP table.
