ARP Inspection
– 402 –
◆ ARP Inspection uses the DHCP snooping bindings database for the list of valid
IP-to-MAC address bindings. ARP ACLs take precedence over entries in the
DHCP snooping bindings database. The switch first compares ARP packets to
any specified ARP ACLs.
◆ If Static is specified, ARP packets are only validated against the selected ACL –
packets are filtered according to any matching rules, packets not matching any
rules are dropped, and the DHCP snooping bindings database check is
bypassed.
◆ If Static is not specified, ARP packets are first validated against the selected ACL;
if no ACL rules match the packets, then the DHCP snooping bindings database
determines their validity.
Parameters
These parameters are displayed:
◆ VLAN – Selects any configured VLAN. (Range: 1-4094; Default: 1)
◆ DAI Status – Enables Dynamic ARP Inspection for the selected VLAN.
(Default: Disabled)
◆ ACL Name – Allows selection of any configured ARP ACLs. (Default: None)
◆ ACL Status – When an ARP ACL is selected, and static mode also selected, the
switch only performs ARP Inspection and bypasses validation against the DHCP
Snooping Bindings database. When an ARP ACL is selected, but static mode is
not selected, the switch first performs ARP Inspection and then validation
against the DHCP Snooping Bindings database. (Default: Disabled)
Web Interface
To configure VLAN settings for ARP Inspection:
1. Click Security, ARP Inspection.
2. Select Configure VLAN from the Step list.
3. Enable ARP inspection for the required VLANs, select an ARP ACL filter to check
for configured addresses, and select the Static option to bypass checking the
DHCP snooping bindings database if required.
4. Click Apply.
