Chapter 49 Configuring Port Security
Configuring Port Security on Access Ports
Step 4
Switch(config-if)# [no] switchport port-security
maximum value
(Optional) Sets the maximum number of secure MAC
addresses for the interface. The range is 1 to 3072; the
default is 1.
To return the interface to the default number of secure
MAC addresses, use the no switchport port-security
maximum value.
Step 5
Switch(config-if)# switchport port-security
[aging {static | time aging_time | type {absolute
| inactivity}]
Sets the aging time and aging type for all secure addresses
on a port.
Use this feature to remove and add PCs on a secure port
without manually deleting the existing secure MAC
addresses while still limiting the number of secure
addresses on a port.
The static keyword enables aging for statically
configured secure addresses on this port.
The time aging_time value specifies the aging time for this
port. Valid range for aging_time is from 0 to 1440 minutes.
If the time is equal to 0, aging is disabled for this port.
The type keyword sets the aging type as absolute or
inactive.
• absolute—All the secure addresses on this port ago
out exactly after the time (minutes) specified and are
removed from the secure address list.
• inactive—The secure addresses on this port age out
only if there is no data traffic from the secure source
address for the specified time period.
To disable port security aging for all secure addresses on
a port, use the no switchport port-security aging time
interface configuration command.
