CHAPTER 4
WEB OPERATION & CONFIGURATION
Out of Order:
The number of LBR PDU received from this “Reply MAC” with incorrect “Transaction ID”.
Link Trace
Enable:
Select the checkbox to enable Link Trace based on transmitting and receiving LTM/LTR PDU. Link Trace is
automatically disabled when all 5 transactions are done with 5 sec. interval - waiting 5 sec. for all LTR in the end. The
LTM PDU is always transmitted as Multi-cast Class 2.
Priority:
The priority to be inserted as PCP bits in TAG (if any).
Peer MEP:
This is only used if the “Unicast MAC” is configured to all zero. The Link Trace Target MAC will be taken
from the “Unicast Peer MAC” configuration of this peer.
Unicast MAC:
This is only used if NOT configured to all zero. This will be used as the Link Trace Target MAC. This is the
only way to configure a MIP as Target MAC.
Time To Live:
This is the LTM PDU TTL value as described in Y.1731. This value is decremented each time forwarded by
a MIP. PDU will not be forwarded when the TTL value reaches zero.
Link Trace State
Transaction ID:
The transaction id is incremented for each LTM send. This value is inserted the transmitted LTM PDU
and is expected to be received in the LTR PDU. Received LTR with wrong transaction id is ignored. There are five
transactions in one Link Trace activated.
Time To Live:
This is the TTL value taken from the LTM received by the MIP/MEP sending this LTR - decremented as if
forwarded.
Mode:
This indicates if it was a MEP/MIP sending this LTR.
Direction:
This indicates if MEP/MIP sending this LTR is ingress or egress.
Relayed:
This indicates if MEP/MIP sending this LTR has relayed or forwarded the LTM.
Last MAC:
The MAC identifying the last sender of the LBM causing this LTR - initiating MEP or previous MIP forwarding.
Next MAC:
The MAC identifying the next sender of the LBM causing this LTR - MIP forwarding or terminating MEP.
Test Signal
Tx/Rx:
Enable or disable test signal to send or receive TST PDU.
Dei:
The DEI to be inserted as PCP bits in TAG (if any).
Priority:
The priority to be inserted as PCP bits in TAG (if any).
Peer MEP:
The TST frame destination MAC will be taken from the “Unicast Peer MAC” configuration of this peer.
Rate:
The TST frame transmission bit rate - in Mega bits pr. second. Limit on Caracal is 400 Mbps. Limit on Serval is
1Gbps.
Size:
The TST frame size. This is entered as the wanted size (in bytes) of a un-tagged frame containing TST OAM PDU -
including CRC (four bytes).
