Description
For aggregated Ethernet, Fast Ethernet, Gigabit
Ethernet, Gigabit Ethernet IQ interfaces, and Gigabit Ethernet PICs
with SFPs (except the 10-port Gigabit Ethernet PIC and the built-in
Gigabit Ethernet port on the M7i router), specify the MAC addresses
from which the interface can receive packets. For this statement to
have any effect, you must include the source-filtering statement
in the configuration to enable source address filtering.
Options
mac-address—MAC
address filter. You can specify the MAC address as nn:nn:nn:nn:nn:nn or nnnn.nnnn.nnnn, where n is
a decimal digit. To specify more than one address, include multiple mac-address options in the source-address-filter statement.
If you enable the VRRP on a Fast Ethernet or Gigabit Ethernet
interface, as described in VRRP and VRRP
for IPv6 Overview, and if you enable MAC source address
filtering on the interface, you must include the virtual MAC address
in the list of source MAC addresses that you specify in the source-address-filter statement. MAC addresses ranging from 00:00:5e:00:01:00 through 00:00:5e:00:01:ff are reserved for VRRP, as defined
in RFC 3768, Virtual Router Redundancy Protocol. When you configure the VRRP group, the group number must be the
decimal equivalent of the last hexadecimal byte of the virtual MAC
address.
On untagged Gigabit Ethernet interfaces, you should not configure
the source-address-filter statement and the accept-source-mac statement simultaneously. On tagged Gigabit Ethernet interfaces,
you should not configure the source-address-filter statement
and the accept-source-mac statement with an identical MAC
address specified in both filters.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
