The fields that can be configured in the table are described below:
Parameter
Description
MA Mode
Select the MA mode here. Options to choose from are:
•
Software
- Specifies that the MA works in the CFM software mode.
•
Hardware
- Specifies that the MA works in the CFM hardware mode.
The CFM hardware mode is used to improve the performance of the CCM
process. In the CFM hardware mode, the CCM packet is processed by
hardware and in general does not need to involve the CPU. In addition, the
CCM interval can be set to the lowest value of 3.3ms which is not supported in
the CFM software mode due to the CPU capability constraints.
The CFM hardware and software mode can be used together. The user can
configure an MA as the CFM hardware mode. Then, all MEPs in the MA will be
working in the CFM hardware mode. For some MAs, if the performance of the
CCM process is considered, e.g. requiring 3.3ms and 10ms CCM interval, and
the MEPs in the MA are down MEPs, the user can use the CFM hardware
mode; For other MAs, if the performance of the CCM process is not a problem,
or up MEPs and MIPs need to be set up, or full CFM function are required, the
CFM software mode is a better choice.
MIP Creation
This option is used to configure the MIP creation for an MA. Select one of the
following options:
•
None
- Specifies not to create the MIP on ports in an MA.
•
Auto
- Specifies that MIPs will be created on any port for this MA, when
there is no MEP configured on that port for the MAs with the same VID at
this MD level or any higher active MD levels, and at the same time there is
an MEP configured on that port for the MA with the same VID at the next
lower active MD level or there is no MA with the same VID at any lower
active MD levels. For an intermediate Switch in an MA, the setting should
be
Auto
in order for the MIPs to be created on this device.
•
Explicit
- Specifies that MIPs will be created on any port for this MA, when
there is no MEP configured on that port for the MAs with the same VID at
this MD level or any higher active MD levels, and at the same time there is
an MEP configured on that port for the MA with the same VID at the next
lower active MD level.
•
Defer
- Specifies to inherit the settings configured for the maintenance
domain that the MA is associated with. This is the default value.
CCM Interval
Select the Continuity Check Message (CCM) interval value here. Options to
choose from are
3.3ms
,
10ms
,
100ms
,
1sec
,
10sec
,
1min
, and
10min
. An
MEP will transmit a CCM packet periodically across the MA. The CCM interval
indicates the interval at which CCMs are sent by a MEP in a MA.
SenderID TLV
This option is used to configure the transmission of the sender ID TLV by MPs
for an MA. Select one of the following options:
•
None
- Specifies not to transmit the sender ID TLV. In the CFM hardware
mode, the value is fixed to none.
•
Chassis
- Specifies to transmit the sender ID TLV with the chassis ID
information.
•
Manage
- Specifies to transmit the sender ID TLV with the managed
address information.
•
Chassis_Manage
- Specifies to transmit the sender ID TLV with the
chassis ID information and the managed address information.
•
Defer
- Specifies to inherit the setting configured for the maintenance
domain that the MA is associated with. This is the default value.
MEPID List
Enter the Maintenance association End Point (MEP) ID contained in the MA
here. The range is from 1 to 8191.
