IP source guard

35

IP source guard is used on client ports to prevent IP source address spoofing. Generally, IP source 
guard is used together with DHCP snooping and Dynamic ARP Inspection on untrusted ports. 

When IP source guard is first enabled, the client port allows only DHCP packets, and blocks all 
other IP traffic. When the system learns a valid IP address on the port, the client port then allows IP 
traffic. Client ports permit only the traffic with valid source IP addresses.

The system learns of a valid IP address from ARP. (For information on how the ARP table is 
populated, refer to 

“ARP entries”

 on page 1002) When it learns a valid IP address, the system loads 

a per-port IP ACL entry permitting the learned source IP address on the port. 

When a new IP source entry binding on the port is created or deleted, the per-port IP ACL will be 
recalculated and reapplied in hardware to reflect the change in IP source binding. 

By default, if the IP source guard is enabled without any IP source binding on the port, an ACL that 
denies all IP traffic is loaded on the port. Similarly, when the IP source guard is disabled, any IP 
source per-port IP ACL will be removed from the interface.

Limits and restrictions

Current implementation with this feature has the following limitations:

•

Works only on routing and virtual interface ports, and does not support Layer 2 switching-only 
ports in VLANs without an assigned IP address on the router.

•

Does not support auto-saving of the learnt ARP entries when DAI is enabled. You must 
manually save the ARP entries before a reboot.

•

Does not provide CLI to disable check for source MAC and source IP in DAI.

Enabling IP source guard

DHCP Snooping should be configured before you enable the IP source guard feature. 

The default setting is disabled. To enable IP source guard on an untrusted port, enter the following 
commands.

BigIron RX(config)# interface ethernet 1/4

BigIron RX(config-if-e10000-1/4)# source guard enable

The commands change the CLI to the interface configuration level for port 1/4 and enable IP 
source guard on the port.

Syntax: [no] source guard enable

Displaying learned IP addresses

To display all IP source bindings configured on all interfaces on a switch, enter a command such as 
the following.

Syntax: show ip source guard ethernet <

port-num

>

BigIron RX#show ip source guard eth 5/20

IP source guard on ethernet 5/20: Enabled
