Usage Guidelines
The ipv6 neighbor binding max-entries command is used to control the content of the binding table. This
command specifies the maximum number of entries that are allowed to be inserted in the binding table cache.
Once this limit is reached, new entries are refused, and the Neighbor Discovery Protocol (NDP) traffic source
with the new entry is dropped.
If the maximum number of entries specified is lower than the current number of entries in the database, no
entries are cleared, and the new threshold is reached after normal cache attrition.
The maximum number of entries can be set globally per VLAN, interface, or MAC addresses.
Examples The following example shows how to specify globally the maximum number of entries inserted into the cache:
switch(config)# ipv6 neighbor binding max-entries 100
Number of entries that can be inserted into the cache.
(Optional) Specifies a neighbor binding limit per
number of VLANs.
(Optional) Specifies a neighbor binding limit per
interface.
(Optional) Specifies a neighbor binding limit per
number of Media Access Control (MAC) addresses.
