IPv6 Source Guard
IPv6 Source Guard is a security feature that filters IPv6 traffic on non-routed, Layer 2
network interfaces based on manually configured entries in the IPv6 Source Guard
table, or dynamic entries in the Neighbor Discovery Snooping table or DHCPv6
Snooping table when either snooping protocol is enabled (refer to the DHCPv6
Snooping commands in the CLI Reference Guide). IPv6 source guard can be used to
prevent traffic attacks caused when a host tries to use the IPv6 address of a
neighbor to access the network. This section describes how to configure IPv6
Source Guard.
Configuring Ports for
IPv6 Source Guard
Use the Security > IPv6 Source Guard > Port Configuration page to filter inbound
traffic based on the source IPv6 address stored in the binding table.
IPv6 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 IPv6 address of a neighbor.
Command Usage
◆ Setting source guard mode to SIP (Source IP) enables this function on the
selected port. Use the SIP option to check the VLAN ID, IPv6 global unicast
source IP address, and port number against all entries in the binding table.
◆ After IPv6 source guard is enabled on an interface, the switch initially blocks all
IPv6 traffic received on that interface, except for ND packets allowed by ND
snooping and DHCPv6 packets allowed by DHCPv6 snooping. A port access
control list (ACL) is applied to the interface. Traffic is then filtered based upon
dynamic entries learned via ND snooping or DHCPv6 snooping, or static
addresses configured in the source guard binding table. The port allows only
IPv6 traffic with a matching entry in the binding table and denies all other IPv6
traffic.
