How to check CP FW ARP age timeout currently? Can CP display it as Cisco device?

Address         Age        Hardware Addr   State      Type  Interface
10.4.9.2        00:35:55   0030.7131.abfc  Dynamic    ARPA  MgmtEth0/RP1/CPU0/0

No, I do not want to know cache timeout value. I want to know real time ARP age timeout value. default is 60s, but after some seconds, how long does it leave? Ths is my question.

You could try something like that to check values, in Expert mode.

ip -statistics neighbour | awk {'print $1; print $5;print"last used/confirmed/updated"; print $9; print"-----------------"'}

You will get something along the lines of this.

a.a.a.a
00:11:22:33:44:55a
last used/confirmed/updated
7/1/7
-----------------
b.b.b.b
aa:cc:22:bb:33:cc
last used/confirmed/updated
0
-----------------
c.c.c.c
ee:55:ff:66:77:ab
last used/confirmed/updated
0
-----------------
d.d.d.d
32:25:15:cc:dd:aa
last used/confirmed/updated
1310219/0/1310218
-----------------

With real IP and MAC of course.

Could you please explain which value is age timeout? I do not understand the meaning of the output argument.
