Configuring maximum learn entries on a port
Configures the maximum number of ND Snooping entries that can be learned on a port.
If the maximum bindings value is configured before enabling ND Snooping, the limit is immediately applied and the bindings are not allowed to exceed the max-bindings value. If the max-bindings value is set after enabling ND Snooping, the following applies:
-
The current bindings are greater than the max-binding value, the configuration is applied as and when the ND Snooping entry ages out.
-
Current bindings are less than that of the value entered, the configuration is immediately applied.
NOTE:
This is similar to DHCP-snooping and DHCPv6–snooping in switches.
