IP Source Guard

IP Source Guard

IP Source Guard is a security feature that restricts IP traffic on untrusted ports. IP Source Guard filters traffic based on the DHCP snooping binding database or the manually configured IP source bindings.

When IP Source Guard is first enabled, only DHCP packets are allowed and all IP traffic is blocked. When the system learns a valid IP address, IP Source Guard then allows IP traffic. Only the traffic with valid source IP addresses is permitted.

SNMP IP Source Guard MIB objects manage information for the configuration of the IP Source Guard feature. There are three tables for IP Source Guard:

fdryIpSrcGuardIfConfigTable - enables or disables IP Source Guard on each physical interface.

fdryIpSrcGuardPortVlanConfigTable - enables or disables IP Source Guard on a port on a VLAN. (Not provided by this switch.)

fdryIpSrcGuardBindTable - provides the IP addresses used for IP Source Guard purposes at each physical interface, with or without specific VLAN memberships. (To be provided at a later date.)

physical interface.

 

 

 

fdryIpSrcGuardIfConfigEntry

N/A

A row indicates if IP Source Guard is enabled or

brcdIp.1.1.3.37.1.1.1

 

disabled on each physical interface. It is indexed by

 

 

ifIndex.

 

 

 

fdryIpSrcGuardIfEnable

Read-write

This object indicates whether IP Source Guard is

brcdIp.1.1.3.37.1.1.1.1

 

enabled on this interface.

Syntax: TruthValue

 

If this object is set to “true”, IP Source Guard is

 

 

enabled. Traffic coming to this interface will be

 

 

forwarded if it is from the list of IP addresses obtained

 

 

from DHCP snooping. Otherwise it is denied.

 

 

If this object is set to “false”, IP Source Guard is

 

 

disabled.
