Connectivity Fault Management
– 526 –
◆ 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 String – IEEE 802.1ag defined character string format.
This is an IETF RFC 2579 DisplayString.
■
ICC Based – ITU-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").
◆ AIS Status – Enables/disables suppression of the Alarm Indication
Signal (AIS). (Default: Disabled)
◆ AIS Period – Configures the period at which AIS is sent in an MA.
(Range: 1 or 60 seconds; Default: 1 second)
◆ AIS Transmit Level – Configure the AIS maintenance level in an MA.
(Range: 0-7; Default is 0)
AIS Level must follow this rule: AIS Level >= Domain Level
◆ AIS Suppress Alarm – Enables/disables suppression of the AIS.
(Default: Disabled)
