Hello,

Does anyone know how to enable or configure Dynamic ARP Inspection on a 2360? I have reviewed all the documentation with no results.

Thanks

look for dhcp snooping and dhcp binding. It is the same feature.
best regards
Silvio

Hello,

Thank you.

I just implemented this configuration.

dhcp-snooping admin-state enable
dhcp-snooping binding admin-state enable
dhcp-snooping port 1/1/24 trust
dhcp-snooping port 2/1/24 trust


Is it complete?
Is there anything else missing?

Can anybody help me ?

[silvio]

you need an isf (ip-source-filter) for all your client-ports. The isf compared the binding table with the arp from the client. If anybody is sending wrong arp (with wrong ip), than he will filtered.
best regards

Hello Silvio,

it works.
THANKS.
sometimes, the dhcp binding table is not filled in the switch while the computer is configured in dynamic dhcp. Which causes the switch to block this computer.
Should I enable dhcp-snooping binding persistency admin-state enable?

I prefere to use this option.
