set dhcpsnooping binding

Example

This example configures port ge.1.1 as a trusted port.

C3(rw)->set dhcpsnooping trust port ge.1.1 enable

set dhcpsnooping binding

Use this command to add a static DHCP binding to the DHCP snooping database.

Syntax

set dhcpsnooping binding mac-address vlan vlan-id ipaddr port port-string

Parameters

mac‐address	Specifies the MAC address of the binding entry.
vlan vlan‐id	Specifies the VLAN of the binding entry.
ipaddr	Specifies the IP address of the binding entry.
port port‐string	Specifies the port of the binding entry.

Defaults

None.

Mode

Switch command, read‐write.

Usage

When enabled globally and on VLANs, DHCP snooping builds its bindings database from DHCP client messages received on untrusted ports. Such entries in the database are dynamic entries which will be removed in response to valid DECLINE, RELEASE, and NACK messages or when the absolute lease time of the entry expires.

You can add static entries to the bindings database with this command.

Example

This example creates a static entry, associating MAC address 00:01:02:33:44:55 with IP address 192.168.10.10 and VLAN 10, port ge.1.1.

C3(rw)->set dhcpsnooping binding 00:01:02:33:44:55 vlan 10 192.168.10.10 port ge.1.1

set dhcpsnooping verify

Use this command to enable or disable DHCP snooping to filter on source MAC address.

Syntax

set dhcpsnooping verify mac-address {enable disable}
