Usage Guidelines

Use the hardware profile ucast6 max-limit command to limit the maximum number of host entries in the host table.

After setting the limit for multicast and IPv6 in the host table, the remaining number of entries are allocated for IPv4 host entries.

Note A limit set by using the hardware profile multicast max-limit command overrides the limit set by using the hardware profile ucast6 max-limit command.

This example shows how to set the maximum number of unicast IPv6 entry limit in the host table: 

switch# configure terminal

switch(config)# hardware profile ucast6 max-limit 2500

Warning!!: The host (v4 & v6) unicast route limits have been changed.

switch(config)#
