The Show Local OAM Information Menu items and options are
described below:
Line Card Operation Mode
Indicates whether the selected port is configuring as OAM visible or
bypass mode.
OAM Bypass Mode – In this mode, the line card receives
OAMPDU packets, but forwards them onto the other port. This
allows Converteon to be used in a network where the Converteon
chassis is not part of the IEEE802.3ah end points. (i.e. in this
mode, the OAM function of the line card is disabled). To configure
as OAM bypass mode, the module will pass all OAMPDUs whose
vendor OUI is not Allied Telesyn.
OAM Visible Mode – In this mode, the line card does respond to
OAMPDU packets. In an unmanaged chassis, the line card will be
in passive mode. In a managed chassis, the line card can either be
in passive or active mode depending on how it is software
configured. For detailed information, refer to “OAM Active and
Passive Mode Behaviors” on page 89. To configure as OAM
visible mode, the module will respond to all OAMPDUs.(default)
Operation Status
Indicates the OAM operational status. Possible values are:
Disabled – The OAM operation has been disabled.
Passive Wait – A station configured in Passive mode waits until
receiving information OAMPDUS with Local Information TLVs
before sending any Information OAMPDU with Local Information
TLVs. By waiting until first receiving an Information OAMPDU with
the Local Information.
Active Send Local – A station configured in Active mode sends
Information OAMPDUs that only contain the Local Information
TLV. While in this state, the local station waits for Information
OAMPDUs received from the remote station.
Send Local and Remote – The flow of frames is generated within
the local and remote stations and across the link during loopback.
OAM Peering Locally Rejected – The configuration of the peer
OAM entity has been rejected by the remote station.
OAM Peering Remotely Rejected – The configuration of the peer
OAM entity has been rejected by the local station.
