DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide Example This example shows how to clear the DAI statistics from VLAN 1. Switch# clear ip arp inspection statistics vlan 1 Switch# 35-4 ip arp inspection filter vlan This command is used to specify an ARP access list to be used for ARP inspection checks for the VLAN. Use the no command to remove the specification. ip arp inspection filter ARP-ACL-NAME vlan VLAN-ID [, | -] [static] no ip arp inspection filter ARP-ACL-NAME vlan VLAN-ID [, | -] [static] Parameters ARP-ACL-NAME vlan VLAN-ID , - static Specifies the access control list name with a maximum of 32 characters. Specifies the VLAN associated with the ARP access list. (Optional) Specifies a series of VLANs, or separate a range of VLANs from a previous range. No space is allowed before and after the comma. (Optional) Specifies a range of VLANs. No space is allowed before and after the hyphen. (Optional) Specifies to drop the packet if the IP-to-Ethernet MAC binding pair is not permitted by the ARP ACL. Default None. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline Use this command to specify an ARP access list to be used for ARP inspection checks for the VLAN. Up to one access list can be specified for a VLAN. The dynamic ARP inspection checks the ARP packets received on the VLAN to verify that the binding pair of the source IP and source MAC address of the packet is valid. The validation process will match the address binging against the entries of the DHCP snooping database. If the command is configured, the validation process will match the address binging against the access list entries and the DHCP snooping database. ARP ACLs take precedence over entries in the DHCP snooping binding database. If the packet is explicitly denied by the access control list, the packet is dropped. If the packet is denied due to the implicit deny, the packet will be further matched against the DHCP snooping binding entries if the keyword "static" is not specified. The implicit denied packet is dropped if the keyword "static" is specified. 381
