Configuring Ip Source Guard For Static Hosts - Cisco Catalyst 3750-E Software Configuration Manual

Configuring IP Source Guard
To delete a static IP source binding entry, use the no ip source global configuration command.
This example shows how to enable IP source guard with source IP and MAC filtering on VLANs 10
and 11:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# ip verify source port-security
Switch(config-if)# exit
Switch(config)# ip source binding 0100.0022.0010 vlan 10 10.0.0.2 interface
gigabitethernet1/0/1
Switch(config)# ip source binding 0100.0230.0002 vlan 11 10.0.0.4 interface
gigabitethernet1/0/1
Switch(config)# end

Configuring IP Source Guard for Static Hosts

Configuring IP Source Guard for Static Hosts on a Layer 2 Access Port
You must configure the ip device tracking maximum limit-number interface configuration command
Note
globally for IPSG for static hosts to work. If you only configure this command on a port without enabling
IP device tracking globally or by setting an IP device tracking maximum on that interface, IPSG with
static hosts rejects all the IP traffic from that interface. This requirement also applies to IPSG with static
hosts on a private VLAN host port.
Beginning in privileged EXEC mode:
Command
Step 1 configure terminal
Step 2
ip device tracking
Step 3
interface interface-id
Step 4
switchport mode access
Step 5 switchport access vlan vlan-id
