User Guidelines
This command is used to control the contents of the Binding table. This command
specifies the maximum number of dynamic entries that can be inserted in the
Binding table cache. After this limit is reached, new entries are refused, and a
Neighbor Discovery Protocol (NDP) traffic source with a 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.
Example
The following example shows how to specify globally the maximum number of
entries that can be inserted into the cache per MAC:
—Specifies a neighbor binding limit per number of VLANs.
number
—Specifies a neighbor binding limit per port.
—Specifies a neighbor binding limit per MAC address.
