display in SHOW IP ARP is blank under interface

[calopez]

Hello,

I issued a SHOW IP ARP command on a router and noticed the field under the interface was "blank" and under Age column had a (-) hyphen.. Does this represent an issue or is this "normal" , all other addresses displayed had the entries filled with the proper router LAN interface and there was a numeric value in the Age column:

Routerabc#show ip arp

Protocol Address Age (min) Hardware Addr Type Interface

Internet 10.1.0.31 4 xxxx.xxxx.xxxx ARPA FastEthernet0/0

Internet 10.1.0.30 - yyyy.yyyy.yyyy ARPA

Any information in the above display on the "blank" interface entry is appreciated.

Regards,

Carlos.

I presume that you are looking at the routers interface adresss.

I think you have a static entry like this

arp A.A.A.A yyyy.yyyy.yyyy ARPA
