domain-name – Domain name. (Range: 1-43 alphanumeric
characters)
ma-name – Maintenance association name. (Range: 1-43
alphanumeric characters)
interval-level – The transmission delay between connectivity check
messages. The setting for this parameter is expressed as levels 4
through 7, which in turn map to specific intervals of time.
(CCM lifetime field options: 4 - 1 second, 5 - 10 seconds,

Port State Port states include:
Up – The port is functioning normally.
Blocked – The port has been blocked by the Spanning Tree Protocol.
No port state – Either no CCM has been received, or nor port status
TLV was received in the last CCM.

Up – The interface is ready to pass packets.
Down – The interface cannot pass packets.
Testing – The interface is in some test mode.
Unknown – The interface status cannot be determined for some
reason.
Dormant – The interface is not in a state to pass packets but is in a
pending state, waiting for some external event.
Not Present – Some component of the interface is missing.
isLowerLayerDown – The interface is down due to state of the lower
layer interfaces.
Crosscheck Status Shows if crosscheck function has been enabled.
