Introduction

The Cisco 892F ISRs have an SFP port that supports auto-media-detection, auto-failover, and remote fault indication (RFI), as described in the IEEE 802.3ah specification.

This is a basic customer configuration for Cisco C892F SFP port. It includes the following elements:

  1. Media Type Selection
  2. Auto-Failover Mode
  3. Speed & Duplex Settings
  4. Configure Backup Port
  5. Ethernet CFM Configuration

Configuration

1. Media Type Selection

SFP Mode:

C892F(config)#int gigabitEthernet 0
C892F(config-if)#media-type ?
  rj45  Use RJ45 connector
  sfp   Use SFP connector
  <cr>
C892F(config-if)#media-type sfp 
GigabitEthernet0: Changing media to SFP.
You may need to update the speed and duplex settings for this interface.
C892F(config-if)#

RJ45 Mode:

C892F(config)#int gigabitEthernet 0
C892F(config-if)#media-type ?
  rj45  Use RJ45 connector
  sfp   Use SFP connector
  <cr>
C892F(config-if)#media-type rj45 
GigabitEthernet0: Changing media to RJ45.
You may need to update the speed and duplex settings for this interface.
C892F(config-if)#

Auto-Detect Mode:

C892F(config)#int gigabitEthernet 0
C892F(config-if)#no media-type 
GigabitEthernet0: Setting default media-type to UNKNOWN
GigabitEthernet0: Changing media to UNKNOWN.
You may need to update the speed and duplex settings for this interface.
C892F(config-if)#


2. Auto-Failover Mode

RJ45 Mode Switchover if SFP fails:

C892F(config)#int gigabitEthernet 0
C892F(config-if)#media-type sfp auto-failover 
GigabitEthernet0: Changing media to SFP.
You may need to update the speed and duplex settings for this interface.

SFP Mode Switchover if RJ45 fails:

C892F(config)#int gigabitEthernet 0
C892F(config-if)#media-type rj45 auto-failover 
GigabitEthernet0: Changing media to RJ45.
You may need to update the speed and duplex settings for this interface.

3. Speed & Duplex Settings

In RJ45 Mode:

C892F(config-if)#int gig0
C892F(config-if)#media-type rj45 
GigabitEthernet0: Changing media to RJ45.
You may need to update the speed and duplex settings for this interface.
C892F(config-if)#speed ?
  10    Force 10 Mbps operation
  100   Force 100 Mbps operation
  1000  Force 1000 Mbps operation
  auto  Enable AUTO speed configuration
C892F(config-if)#speed 100
C892F(config-if)#duplex ?
  auto  Enable AUTO duplex configuration
  full  Force full duplex operation
  half  Force half-duplex operation
C892F(config-if)#duplex full 

In SFP Mode (Only for GLC-GE-100FX):

C892F(config-if)#int gig0
C892F(config-if)#media-type sfp 
GigabitEthernet0: Changing media to SFP.
You may need to update the speed and duplex settings for this interface.
C892F(config-if)#speed ?
  100   Force 100 Mbps operation
C892F(config-if)#speed 100
C892F(config-if)#duplex ?
  full  Force full duplex operation
  half  Force half-duplex operation
C892F(config-if)#duplex full 

4. Configure Backup port

SFP mode with failover option to RJ45 prior switching to backup Fe8 Port:

C892F(config)#int gigabitEthernet 0 
C892F(config-if)#media-type sfp auto-failover 
GigabitEthernet0: Changing media to SFP.
You may need to update the speed and duplex settings for this interface.
C892F(config-if)#backup interface fastEthernet 8 

5. Ethernet CFM Configuration

C892F(config)#ethernet cfm ieee
C892F(config)#ethernet cfm global
C892F(config)#ethernet cfm traceroute cache
C892F(config)#ethernet cfm domain Customer_Domain level 7
C892F(config-ecfm)#service SID_CE1 vlan 711 direction down
C892F(config-ecfm-srv)#continuity-check
C892F(config-ecfm-srv)#service SID_CE2 vlan 721 direction down
C892F(config-ecfm-srv)#continuity-check
C892F(config-ecfm-srv)#continuity-check loss-threshold 2
C892F(config-ecfm-srv)#ethernet cfm logging
C892F(config)#interface gig0
C892F(config-if)#media-type sfp 
GigabitEthernet0: Changing media to SFP.
You may need to update the speed and duplex settings for this interface.
C892F(config-if)#ethernet cfm mep domain Customer_Domain mpid 921 vlan 721
C892F(config-if-ecfm-mep)#ethernet cfm mep domain Customer_Domain mpid 911 vlan 711
C892F(config-if-ecfm-mep)#interface gig0.100
C892F(config-subif)#encapsulation dot1Q 711
C892F(config-subif)#ip address 4.0.0.1 255.0.0.0
C892F(config-subif)#interface gig0.200
C892F(config-subif)#encapsulation dot1Q 721
C892F(config-subif)#ip address 2.0.0.1 255.0.0.0
C892F(config-subif)#end
