RE: ARP timeout issue

I think there is no issues with the config part as it was working fine
previously. It's a pre-configured switch for one of our customers whom we
manage.

Thank you,

Sorry....

I did not see this at first:

switchport port-security aging time 2

Why?

Remove this command and try it:

Hi All,

(I am a member of groupstudy but as we don't have access to yahoo inside
here I am sending from my cisco ID.)

I have a switch 3750.scenario is like this:

Port fa1/0/14 of the switch is connected to a printer whose ip is
10.101.25.141. I am able to ping the printer from switch and after pinging
it I can see it in the arp table but within couple of seconds or when I do
clear arp I loose the printer from my arp table and left with only two
entries.

sALBEles70#sh arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 10.101.25.26 - 0025.46fe.5641 ARPA Vlan25

Internet 10.101.25.141 0 0007.4d2d.ee88 ARPA Vlan25

sALBEles70#sh run int fa1/0/14
Building configuration...

Current configuration : 473 bytes

end

I have tried increasing the arp timeout of the interface to 1 min but no
joy. TAC has replaced the switch two times but still no joy. Wonder why the
arp table is not holding the printer's entry. Any Clue????

Thank you,
