Configuring ETH-CSF

Follow these steps to configure ETH-CSF and verify the configuration.

Before you begin

Note

Refer to the "802.1ag Connectivity Fault Management" chapter in the Extreme SLX-OS Layer 2 Switching Configuration Guide. For command details, see the Extreme SLX-OS Command Reference.

Procedure

Configure ETH-CSF on a physical interface.
1. Enter global configuration mode.
```
device# configure terminal
```
2. Enter the protocol cfm command to enter Connectivity Fault Management (CFM) protocol configuration mode.
```
device(config)# protocol cfm
```
3. In CFM protocol configuration mode, enter the domain-name command to specify a Maintenance Domain, ID, and level.
```
device(config-cfm)# domain-name md1 id 1 level 3
```
4. Enter the ma-name command to specify an MA name, ID, VLAN, and priority.
```
device(config-cfm-md-md1)# ma-name ma1 id 1 vlan 10 priority 7
```
5. Enter the mep command to specify an MEP ID, state, and interface.
```
device(config-cfm-ma-ma1)# mep 1 down ethernet 1/1
```
6. Enter the client-interface command to specify a client interface, CSF type, and transmission period.
```
device(config-cfm-ma-mep-1)# client-interface ethernet 1/1 csf-type loss-of-signal tx-period 1-minute
```

To configure ETH-CSF on a port-channel interface, configure it as follows.

device# configure terminal
Entering configuration mode terminal
device(config)# protocol cfm 
device(config-cfm)# domain-name md1 id 1 level 3
device(config-cfm-md-md1)# ma-name ma1 id 1 vlan 10 priority 7
device(config-cfm-md-ma-ma1)# mep 1 down port-channel 100
device(config-cfm-md-ma-mep-1)# client-interface port-channel 200 csf-type loss-of-signal tx-period 1-minute

Enter the show cfm y1731 client-signal-fail command to verify the configuration.

device# show cfm y1731 client-signal-fail

Enter the clear cfm y1731 client-signal-fail statistics command to clear the statistics.
```
device# clear cfm y1731 client-signal-fail statistics
```
