Mode This parameter specifies the mode of the OAM client on
the line card. The possible values are:
ˆ Passive – This sets the client’s mode to Passive.
Clients in the Passive mode can not initiate the
Discovery process or send Loopback Control
OAMPDUs or Variable Request OAMPDUs. This is
the default setting.
ˆ Active – This setting sets the client’s mode to Active.
Clients in this mode can initiate the Discovery
process. This is the appropriate setting for the OAM-
based features on the AT-CM Line Cards.
Maximum
OAMPDU
Size This parameter specifies the maximum size in octets of
the OAMPDUs. The OAM clients negotiate the maximum
OAMPDU size during the Discovery process. If a client
receives an Information OAMPDU from its OAM
counterpart with a different value for the maximum
OAMPDU size, it uses the smaller value. For instance, if
a client receives from its remote OAM counterpart an
Information OAMPDU that has a smaller value for the
maximum OAMPDU size than its own value, the client
uses the remote client’s value. The range of this value is
64 to 1518 octets. The default value is 1518 octets.
Unidirec-
tional
Support This parameter controls whether or not the OAM client
sends OAMPDUs if the receiver connector on the fiber
optic port of Port A is not receiving a signal or network
traffic. The possible values are:
ˆ Yes – The OAM client sends OAMPDUs even when
the receive fiber optic connector on the fiber optic
port on port A is not receiving a signal or network
traffic. This is the default setting.
ˆ No – The OAM client sends OAMPDUs only when
the receive fiber optic connector on the fiber optic
port on port A is receiving a signal or network traffic,
and the port has established a link with its remote
counterpart.
