Default level
2: System level
Parameters
auto: Specifies the automatic mode.
default-gateway gateway-ip: Specifies the IP address of the default gateway in the manual mode.
Description
Use the mac-forced-forwarding command to enable MFF and specify an MFF operating mode. To
enable the manual mode, you need to specify a default gateway.
Use the undo mac-forced-forwarding command to disable MFF.
By default, MFF is disabled.
If you execute this command repeatedly, the last configuration takes effect.
If the automatic mode is specified, make sure that DHCP snooping works normally; if the manual mode
is configured, make sure that ARP snooping works normally.
For a network (or VLAN) with IP addresses manually configured, the gateway IP address should be
manually configured with the mac-forced-forwarding default-gateway gateway-ip command; for a
network (or VLAN) running DHCP, the gateway IP address can be manually configured with the
mac-forced-forwarding default-gateway gateway-ip command, or can be resolved from the Option field
in the DHCP messages.
Examples
# Enable MFF in the automatic mode for VLAN 1.
