set arpinspection filter

set arpinspection filter

Use this command to create an ARP ACL and then to assign an ACL to a VLAN, optionally as a static mapping.

Syntax

set arpinspection filter name {permit ip host sender-ipaddrmac host sender-macaddrvlan vlan-range[static]}

Parameters

name

Specifies the name of the ARP ACL.

permit

Specifies that a permit rule is being created.

 

 

ip host sender‐ipaddr

Specifies the IP address in the rule being created.

 

 

mac host

Specifies the MAC address in the rule being created.

sender‐macaddr

 

 

 

vlan vlan‐range

Specifies the VLAN or VLANs to which this ARP ACL is assigned.

 

 

static

(Optional) Specifies that this ARP ACL configures static mappings for

 

the VLAN or VLANs.

 

 

Defaults

None.

Mode

Switch command, read‐write.

Usage

ARP ACLs are used to define static mappings for DAI. ARP ACLs are completely independent of ACLs used for QoS. A maximum of 100 ARP ACLs can be configured. Within an ACL, a maximum of 20 rules can be configured.

A static mapping associates an IP address to a MAC address on a VLAN. DAI consults its static mappings before it consults the DHCP snooping bindings database — thus, static mappings have precedence over DHCP snooping bindings.

Example

This example creates an ACL named staticARP and creates a permit rule for IP address 192.168.1.10. Then, the ACL is assigned to a VLAN as a static mapping.

C3(su)->set arpinspection filter staticARP permit ip host 192.168.1.10 mac host 00:01:22:33:44:55

C3(su)->set arpinspection filter staticARP vlan 10 static

show arpinspection access-list

Use this command to display ARP access list configuration information.

Syntax

show arpinspection access-list [acl-name]
