Enable IPv6 source guard on a port for the Switch to check incoming IPv6 packets on that port. A
packet is allowed when it matches any entry in the IPSG binding table. If a user tries to send IPv6 packets
to the Switch that do not match an entry in the IPSG binding table, the Switch will drop these packets.
The Switch forwards matching traffic normally.
26.12 IPv6 Source Binding Status
Use this screen to look at the current IPv6 dynamic and static bindings and to remove dynamic bindings
based on IPv6 address and/or IPv6 prefix. Bindings are used to distinguish between authorized and
unauthorized packets in the network. The Switch learns the bindings by snooping DHCP packets
(dynamic bindings) and from information provided manually by administrators (static bindings). To open
this screen, click Advanced Application > IP Source Guard > IPv6 Source Binding Status.
