Making Changes to an Access Profile
You can make a change to an access profile, after the change has
been applied, to form an access policy. However, the propagation of
the change depends on the protocol and policy involved.
Propagation of changes applied to RIP, DVMRP, and PIM access
policies depend on the respective protocol timers to age-out entries.
Changes to profiles applied to OSPF typically require rebooting the
switch, or disabling and re-enabling OSPF on the switch.
