Configuring Static MAC Addresses
Cisco Small Business SG200 Series 8-port Smart Switch 128

• MAC Address— Enter the static MAC address.
• Status—Select a status for this static MAC address:
- Permanent—When this status is selected, the static MAC address does
not expire. Note, however, that if the switch is rebooted, the entry is not
restored unless the Running Configuration file type was copied to the
Startup Configuration file type. See Copying and Saving Configuration
Files.
- Delete on Timeout—When this status is selected, the static MAC
address is static but may expire due to inactivity. In this respect, it is
treated like a dynamically learned MAC address. See the Dynamic
Address Settings to set the aging period.
- Secure—When this status is selected, the MAC address is secured and
is used in conjunction with the Port Security feature. When a MAC
address is secured at a port, packets that originate from the MAC
address can only be ingressed from the secured port. Otherwise, the
packets are discarded. If port security is disabled on the port, the MAC
address is deleted from the static MAC address list. When Port Security
is enabled at a port, the port can support a maximum of 256 static and
dynamic MAC addresses. (For more information, see Enabling Port
Security).
STEP 4 Click Apply and then click Close. Your changes are saved to the Running
Configuration.
NOTE To delete a static MAC address, select it in the table and click Delete.
