IPv4 Source Guard is a security feature that filters IP traffic on network 

interfaces based on manually configured entries in the IP Source Guard 

table, or dynamic entries in the DHCP Snooping table when enabled (see 

"DHCP Snooping" on page 415

). IP source guard can be used to prevent 

traffic attacks caused when a host tries to use the IP address of a neighbor 

to access the network. This section describes how to configure IP Source 

Guard.

Use the Security > IP Source Guard > Port Configuration page to set the 

filtering type based on source IP address, or source IP address and MAC 

address pairs.

IP Source Guard is used to filter traffic on an insecure port which receives 

messages from outside the network or fire wall, and therefore may be 

subject to traffic attacks caused by a host trying to use the IP address of a 

neighbor.

Setting source guard mode to SIP (Source IP) or SIP-MAC (Source IP 

and MAC) enables this function on the selected port. Use the SIP option 

to check the VLAN ID, source IP address, and port number against all 

entries in the binding table. Use the SIP-MAC option to check these 

same parameters, plus the source MAC address. If no matching entry is 

found, the packet is dropped.

N

OTE

:

 Multicast addresses cannot be used by IP Source Guard.

◆

When enabled, traffic is filtered based upon dynamic entries learned via 

DHCP snooping (see 

"DHCP Snooping" on page 415

), or static 

addresses configured in the source guard binding table.

◆

If IP source guard is enabled, an inbound packet’s IP address (SIP 

option) or both its IP address and corresponding MAC address (SIP-

MAC option) will be checked against the binding table. If no matching 

entry is found, the packet will be dropped.

◆

Filtering rules are implemented as follows:

■

If DHCP snooping is disabled (see 

page 418

), IP source guard will 

check the VLAN ID, source IP address, port number, and source 

MAC address (for the SIP-MAC option). If a matching entry is found 

in the binding table and the entry type is static IP source guard 

binding, the packet will be forwarded.
