Configuring Gigabit Ethernet Remote Failure Indication (RFI)
Example 4-2 shows how to do an initial configuration of a Gigabit Ethernet interface with
autonegotiation and an IP address.
Example 4-2 Initial Configuration of a Gigabit Ethernet Interface
Router(config)# interface gigabitethernet 0
Router(config-if)# ip address 10.1.2.3 255.0.0.0
Router(config-if)# negotiation auto
Router(config-if)# no shutdown
Router(config-if)# end
Router# copy running-config startup-config
Configuring Gigabit Ethernet Remote Failure Indication (RFI)
Remote Failure Indication (RFI) is part of the IEEE 802.3z standard and is sent to exchange failure
information as part of link negotiation. This feature improves communication between non-Cisco
equipment and the ML1000-2. RFI is not on by default but can be turned on by the user. Disabling RFI
is sometimes necessary when a non-Cisco piece of equipment does not support the IEEE 802.3z standard
implementation of RFI.
RFI on the ML-Series card supports bi-directional RFI. When there is a a local fault on the ML-Series
card, the ML-Series card will raise a local CARLOSS alarm and send its link partner an RFI. If an
ML-Series card receives an RFI from its link partner, it raises the AUTONEG-RFI alarm and shuts down
the Gigabit Ethernet port.
To enable RFI on a Gigabit Ethernet interface, perform the following procedure, beginning in global
configuration mode:
Example 4-3 shows how to do an initial configuration of RFI on a Gigabit Ethernet interface.
Example 4-3 RFI Configuration of a Gigabit Ethernet Interface
Router(config)# interface gigabitethernet 0
Router(config-if)# rfi auto
Router(config-if)# end
Step 6 Router(config)# end Returns to privileged EXEC mode.
Step 7 Router# copy running-config startup-config (Optional) Saves configuration changes to
TCC2/TCC2P flash database.
Command Purpose
Command Purpose
Step 1 Router (config)# interface gigabitethernet
number
Activates interface configuration mode to
configure the Gigabit Ethernet interface.
Step 2 Router(config-if)# [no] rfi auto Enables IEEE 802.3z standard RFI.
The no form of the command disables RFI.
Step 3 Router(config)# end Returns to privileged EXEC mode.
Step 4 Router# copy running-config startup-config (Optional) Saves configuration changes to
TCC2/TCC2P flash database.
