Table 75: SOAM MA/MEG Configuration Parameters
Parameter
Definition
MD (ID, Name)
Select the MD to which you are assigning the MEP.
MA/MEG short name
Enter a name for the MEG (up to 44 alphanumeric characters).
MEG Level
Select a MEG level (0-7). The MEG level must be the same for MEGs
on both sides of the link. Higher levels take priority over lower levels.
If MEGs are nested, the OAM flow of each MEG must be clearly
identifiable and separable from the OAM flows of the other MEGs. In
cases where the OAM flows are not distinguishable by the Ethernet
layer encapsulation itself, the MEG level in the OAM frame
distinguishes between the OAM flows of nested MEGs.
Eight MEG levels are available to accommodate different network
deployment scenarios. When customer, provider, and operator data
path flows are not distinguishable based on means of the Ethernet
layer encapsulations, the eight MEG levels can be shared among them
to distinguish between OAM frames belonging to nested MEGs of
customers, providers and operators. The default MEG level
assignment among customer, provider, and operator roles is:
•
The customer role is assigned MEG levels 6 and 7.
•
The provider role is assigned MEG levels 3 through 5.
•
The operator role is assigned MEG levels: 0 through 2.
The default MEG level assignment can be changed via a mutual
agreement among customer, provider, and/or operator roles.
The number of MEG levels used depends on the number of nested
MEs for which the OAM flows are not distinguishable based on the
Ethernet layer encapsulation.
CCM Interval
The interval at which CCM messages are sent within the MEG. Options
are:
•
1 second (default)
•
10 seconds
•
1 minute
•
10 minutes
It takes a MEP 3.5 times the CCM interval to determine a change in
the status of its peer MEP. For example, if the CCM interval is 1
second, a MEP will detect failure of the peer 3.5 seconds after it
receives the first CCM failure message. If the CCM interval is 10
minutes, the MEP will detect failure of the peer 35 minutes after it
receives the first CCM failure message.
Service ID
Select an Ethernet service to which the MEG belongs. You must define
the service before you configure the MEG.
