Cisco Systems 3560 Manual De Usuario

To disable IP source guard with source IP address filtering, use the no ip verify source interface 
configuration command. 

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 gigabitethernet0/1

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 

Switch(config)# ip source binding 0100.0230.0002 vlan 11 10.0.0.4 interface 

Switch(config)# end

or 

Enable IP source guard with source IP address filtering.

Enable IP source guard with source IP and MAC address filtering.

When you enable both IP Source Guard and Port Security by 
using the ip verify source port-security interface configuration 
command, there are two caveats:

The DHCP server must support option 82, or the client is not 
assigned an IP address.

The MAC address in the DHCP packet is not learned as a secure 
address. The MAC address of the DHCP client is learned as a 
secure address only when the switch receives non-DHCP data 
traffic. 

Return to global configuration mode.

ip source binding mac-address vlan 
vlan-id ip-address inteface interface-id

Add a static IP source binding.

Enter this command for each static binding.

Return to privileged EXEC mode.

show ip verify source [interface 
interface-id]

Display the IP source guard configuration for all interfaces or for a 
specific interface.

show ip source binding [ip-address] 
[mac-address] [dhcp-snooping | static] 
[inteface interface-id] [vlan vlan-id] 

Display the IP source bindings on the switch, on a specific VLAN, or on 
a specific interface.

(Optional) Save your entries in the configuration file.
