Maintenance
Domain (MD)
Level
Select a level (0-7) under which you want to create an MA.
MD Name
Enter a descriptive name for the MD (Maintenance Domain). This field only appears if the
Y.1731
field is disabled.
MA ID
Enter a descriptive name to identify the Maintenance Association. This field only appears if the
Y.1731
field is disabled.
MEG ID
Enter a descriptive name to identify the Maintenance Entity Group. This field only appears if the
Y.1731
field is enabled.
802.1Q VLAN ID
Type a VLAN ID (1-4094) for this MA.
Local MEP ID
Enter the local Maintenance Endpoint Identifier (1~8191).
CCM
Select
Enable
to continue sending MEP information by CCM (Connectivity Check Messages).
When CCMs are received the Zyxel Device will always process it, whether
CCM
is enabled or
not.
Remote MEP ID
Enter the remote Maintenance Endpoint Identifier (1~8191).
Test the connection to another Maintenance End Point (MEP)
Destination
MAC Address
Enter the target device’s MAC address to which the Zyxel Device performs a CFM loopback and
linktrace test.
Test Result
Loopback
Message (LBM)
This shows
Pass
if a Loop Back Messages (LBMs) responses are received. If LBMs do not get a
response it shows
Fail
.
Linktrace
Message (LTM)
This shows the MAC address of MEPs that respond to the LTMs.
Apply
Click this button to save your changes.
Send Loopback
Click this button to have the selected MEP send the LBM (Loop Back Message) to a specified
remote end point.
Send Linktrace
Click this button to have the selected MEP send the LTMs (Link Trace Messages) to a specified
remote end point.
