Parameters DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide 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 interfaces, or separate a range of interfaces from a previous range. No space is allowed before and after the comma. (Optional) Specifies a range of interfaces. 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 binding against the entries of the DHCP snooping database. If the command is configured, the validation process will match the address binding 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. Example This example shows how to apply the ARP ACL static ARP list to VLAN 10 for DAI. Switch# configure terminal Switch(config)# ip arp inspection filter static-arp-list vlan 10 Switch(config)# 26-5 ip arp inspection limit This command is used to limit the rate of incoming ARP requests and responses on an interface. Use the no form of the command to return to the default settings. ip arp inspection limit {rate VALUE [burst interval SECONDS] | none} no ip arp inspection limit Parameters 234
