28.4 IPv6 So urc e Binding Sta tus
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 Adva nc e d Applic a tio n > IP Sourc e G ua rd > IPv6 So urc e Binding Sta tus.

Specify how you want the Switch to remove dynamic IPv6 source binding entries when you
click Flush.
• Select All to remove all of the dynamic entries from the IPv6 source binding table.
• Select IPv6 Addre ss and enter an IPv6 address to remove the dynamic entries snooped
with the specified IPv6 address.
• Select IPv6 Pre fix and enter a Prefix address to remove the dynamic entries snooped with
the specified Prefix address.
Flush Click this to remove dynamic IPv6 source binding entries according to your selections.
Cancel Click this to reset the values above based or if not applicable, to clear the fields above.
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, 2d3h4m 5s 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.
