Each MA name must be unique within the CFM domain.
Primary VLAN – Service VLAN ID. (Range: 1-4094)
This is the VLAN through which all CFM functions are executed for this MA.
MIP Creation Type – Specifies the CFM protocol’s creation method for
maintenance intermediate points (MIPs) in this MA:
Default – MIPs can be created for this MA on any bridge port through
which the MAs VID can pass.
Explicit – MIPs can be created for this MA only on bridge ports through
which the MAs VID can pass, and only if a maintenance end point (MEP) is
created at some lower MA Level.
None – No MIP can be created for this MA.
Configuring Detailed Settings for a Maintenance Association
MD Index – Domain index. (Range: 1-65535)
MA Index – MA identifier. (Range: 1-2147483647)
MA Name Format – Specifies the name format for the maintenance
association as IEEE 802.1ag character based, or ITU-T SG13/SG15 Y.1731 defined
ICC-based format.
Character StringIEEE 802.1ag defined character string format. This is an
IETF RFC 2579 DisplayString.
ICC BasedITU-T SG13/SG15 Y.1731 defined ICC based format.
Interval Level – The delay between sending CCMs. The setting for this
parameter is expressed as levels 4 through 7, which in turn map to specific
intervals of time. (Options: 4 - 1 second, 5 - 10 seconds, 6 - 1 minute, 7 - 10
minutes)
Connectivity Check – Enables transmission of CCMs. (Default: Disabled)
Cross Check – Enables cross-checking between a static list of MEPs assigned to
other devices within the same maintenance association and the MEPs learned
through CCMs.
Before starting the cross-check process, first configure the remote MEPs that
exist on other devices inside the maintenance association using the Remote
MEP List (see "Configuring Remote Maintenance End Points"). These remote
MEPs are used in the cross-check operation to verify that all endpoints in the
specified MA are operational.
The cross-check start delay, which sets the maximum delay this device waits for
a remote MEP to come up before starting the cross-check operation, is a
domain-level parameter. To set this parameter, use the CFM MD Configuration
screen (see "Configuring CFM Maintenance Domains").
