75.8 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
SECURITY > IPv6 Source Guard > IP Static Binding > IP Source Binding Status .
Figure 372 SECURITY > IPv6 Source Guard > IP Static Binding > IP Source Binding Status
The following table describes the labels in this screen.

Index This field displays a sequential number for each binding.
Source Address This field displays the source IP address in the binding. If the entry is blank, this field will not be
checked in the binding.
MAC Address This field displays the source MAC address in the binding. If the entry is blank, this field will not
be checked in the binding.
VLAN This field displays the source VLAN ID in the binding. If the entry is blank, this field will not be
checked in the binding.
Port This field displays the port number in the binding. If this field is blank, the binding applies to all
ports.
Lease This field displays how many days, hours, minutes, and seconds the binding is valid; for
example,
2d3h4m5s means the binding is still valid for 2 days, 3 hours, 4 minutes, and 5
seconds. This field displays infinity if the binding is always valid (for example, a static binding).
Type This field displays how the Switch learned the binding.
S : This static binding was learned from information provided manually by an administrator.
DH : This dhcp-snooping binding was learned by snooping DHCP packets.
