switchport port-security
[maximum value [vlan {vlan-list |
{access | voice}}]]
(Optional) Set the maximum number of secure MAC addresses for the
interface. The maximum number of secure MAC addresses that you can
configure on a switch stack is set by the maximum number of available MAC
addresses allowed in the system. This number is set by the active Switch
Database Management (SDM) template. See Chapter 8, “Configuring the
Switch SDM Template.”This number is the total of available MAC addresses,
including those used for other Layer 2 functions and any other secure MAC
addresses configured on interfaces.
(Optional) vlan—set a per-VLAN maximum value
Enter one of these options after you enter the vlan keyword:
• vlan-list—On a trunk port, you can set a per-VLAN maximum value on
a range of VLANs separated by a hyphen or a series of VLANs separated
by commas. For nonspecified VLANs, the per-VLAN maximum value is
used.
• access—On an access port, specify the VLAN as an access VLAN.
• voice—On an access port, specify the VLAN as a voice VLAN.
Note The voice keyword is available only if a voice VLAN is configured on
a port and if that port is not the access VLAN. If an interface is
configured for voice VLAN, configure a maximum of two secure
MAC addresses.
