IPv6 source guard maximum bindings must be set to a value higher

than DHCPv6 snooping maximum bindings and ND snooping maximum

If IPv6 source guard, ND snooping, and DHCPv6 snooping are enabled

on a port, the dynamic bindings used by ND snooping, DHCPv6

snooping, and IPv6 source guard static bindings cannot exceed the

maximum allowed bindings set by the ipv6 source-guard max-

binding command. In other words, no new entries will be added to the

IPv6 source guard binding table.

If IPv6 source guard is enabled on a port, and the maximum number of

allowed bindings is changed to a lower value, precedence is given to

deleting entries learned through DHCPv6 snooping, ND snooping, and

then manually configured IPv6 source guard static bindings, until the

number of entries in the binding table reaches the newly configured

maximum number of allowed bindings.

This example sets the maximum number of allowed entries in the binding

table for port 5 to one entry.

Console(config)#interface ethernet 1/5

Console(config-if)#ipv6 source-guard max-binding 1

Console(config-if)#

This command shows whether IPv6 source guard is enabled or disabled on

each interface, and the maximum allowed bindings.
