I used to be able to do a "show arp vrf all | inc x.x.x.x in the 9000 series routers. We recently switched over to 8500 series. It appears I can't do that command. Is there a work around?

Try use
Show arp vrf *
If "all" not work

Sorry, That doesn't work. If someone has experience with the 8500 series, that would be great.

Hello @steven-l-letterly-civ ,
use
show ip vrf
to get a list of configured VRFs on the device then you need to issue
show arp vrf <vrf-name> | inc x.x.x.x
for each vrf-name in the list
Hope to help

Thank you. But, I want to include the mac address instead of IP address. I should have posed question differently. There is no way to know which VRF with just a MAC address.

Good day to you @steven-l-letterly-civ
In the Cisco 8500 series routers, the command syntax might differ slightly from the 9000 series. If you are looking for ARP entries in a specific VRF and you used to use show arp vrf all | inc x.x.x.x, you can try the following alternative commands to achieve similar results:
The exact command can vary depending on the software version and specific configurations on your 8500 series routers.
Now, If these commands do not work, you may want to refer to the following websites (
Both versions maintain a professional tone and clear direction):
Additionally, you can try exploring available commands by using the help feature: show ip arp ?
Hope this was helpful, and feel free to reach out if the issue persists.

Hello. So, when I do "show ip arp summary" it shows 15446 IP ARP entries, 233 of them incomplete. That is all. No table. When a do a "show ip arp <vrf-name> | inc <IP address>, that doesn't work either.

friend
I will give you a trick here
do
show ? <<- do you see arp ? if no then do
show ip ? <<- you see arp here sure if above not show that then do
show ip arp ? <<- do you see ALL or vrf if vrf do
show ip arp vrf ? <<- are router ask name enter name then do
show ip arp vrf <> ? <<- do you see | if yes add it
show ip arp vrf <> | etc....
this trick you can use in any cisco platfrom no need more ask about command anymore
