Usage Guidelines PandV is a TCAM region containing entries which mask in both the port and VLAN tag portions of the
flow label.
PorV is a TCAM region containing entries which mask in either the port or VLAN tag portion of the
flow label, but not both.
A balance of 1 allocates the minimum number of PandV region entries and the maximum number of
PorV region entries. A balance of 99 allocates the maximum number of PandV region entries and the
minimum number of PorV region entries. A balance of 50 allocates equal numb ers of PandV and PorV
region entries in the specified TCAM.
Balances for the four TCAMs can be modified independently.
Examples This example shows how to enable the MAC notification trap when a MAC address is added to a port:
Switch# configure terminal
Switch(config)# access-list hardware region feature input balance 75
Switch(config)#
