DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Usage Guideline When a VLAN is enabled for ARP inspection, the ARP packets, including both the ARP request and response packet belonging to the VLAN arriving at the untrusted interface will be validated. If the IP-to-MAC address binding pair of the source MAC address and the source IP address is not permitted by the ARP ACL or the DHCP snooping binding database, the ARP packet will be dropped. In addition to the address binding check, the additional check defined by the IP ARP inspection validate command will also be checked. Example This example shows how to enable ARP inspection on VLAN 2. Switch#configure terminal Switch(config)# ip arp inspection vlan 2 Switch(config)# 23-10 ip arp inspection vlan logging This command is used to control the type of packets that are logged. Use the no form of this command to revert to the default settings. ip arp inspection vlan VLAN-ID [, | -] logging {acl-match {permit | all | none} | dhcp-bindings {permit | all | none}} no ip arp inspection vlan VLAN-ID [, | -] logging {acl-match | dhcp-bindings} Parameters VLAN-ID , - acl-match acl-match permit acl-match all acl-match none dhcp-bindings dhcp-bindings permit dhcp-bindings all dhcp-bindings none Specifies the VLAN to enable or disable the logging control function.
