Chapter 6: Security
• Age/Hold: If at least one user module has decided to block this MAC address, it will stay in the blocked state until the hold time
(measured in seconds) expires. If all user modules have decided to allow this MAC address to forward, and aging is enabled, the
Port Security module will periodically check that this MAC address still forwards traffic. If the age period (measured in seconds)
expires and no frames have been seen, the MAC address will be removed from the MAC table. Otherwise a new age period
will begin.
If aging is disabled or a user module has decided to hold the MAC address indefinitely, a dash (-) will be shown.
