
If assigned source MEP is invalid, ping unsuccessfully. For example, assigned
source MEP is not existing or CFM of the source MEP interface is disabled;

If assigning destination MEP ID to perform ping operation, ping unsuccessfully
when fail to find destination MEP MAC address according to MEPID;

Operation unsuccessful if other users are using the assigned source MEP to
perform ping operation.
8.2.8 Configuring fault location
Configure CFM fault location for the A10E/A28E as below.
Step
Configuration
Description
1
Alpha-A28E#config
Enter global configuration mode.
2
Alpha-
A28E(config)#ethe
rnet cfm
traceroute cache
enable
(Optional) enable fault location database function. In
enable status, system trace route information via database
storing protocol, the command of show ethernet cfm
traceroute cache can show at any time. In disable status,
result of traceroute will be cleared after executing
traceroute. Disable by default, the command of ethernet
cfm traceroute cache disable can disable it.
3
Alpha-
A28E(config)#ethe
rnet cfm
traceroute cache
hold-time minute
(Optional) configure data hold time for fault location
database. You can set data hold time when fault location
database function is enabled. Hold time is 100 minutes
by default.
4
Alpha-
A28E(config)#ethe
rnet cfm
traceroute cache
size size
(Optional) configure saved data amount. You can set the
saved data amount when the function is enabled. It is 100
by default; does not save data if the function is disabled.
5
Alpha-
A28E(config)#serv
ice cisid level
level
Enter service instance configuration mode.
6
Alpha-
A28E(config-
service)#tracerou
te { mac-address
| mep mep-id }
[ ttl ttl ]
[ source mep-id ]
Execute Layer 2 Traceroute function for fault locating.
By default, packets TLV size is 64, search an available
source MEP by automation.
CFM should find MAC address of destination MEP by
mep-id to complete traceroute operation if Layer 2
traceroute operation is operated by specified destination
mep-id. Users can find the following content by data
base of RMEP: data information of RMEP is saved in
RMEP database in MEP after source MEP found RMEP
and it is stable, you can find MAC address of RMEP
according to mep-id in RMEP database.

Make sure global CFM function enable before executing this command, otherwise
the command will be executed unsuccessfully;
