DESCRIPTION
The remote device uses this information to determine what functions are supported.
This field displays the OAM mode. The device in active mode (typically the service
provider's device) controls the device in passive mode (typically the subscriber's
device).
Active: The Switch initiates OAM discovery; sends information PDUs; and may send
event notification PDUs, variable request/response PDUs, or loopback control PDUs.
Passive: The Switch waits for the remote device to initiate OAM discovery; sends
information PDUs; may send event notification PDUs; and may respond to variable
request PDUs or loopback control PDUs.
The Switch might not support some types of PDUs, as indicated in the fields below.
This field indicates whether or not the Switch can send information PDUs to transmit
fault information when the receive path is non-operational.
This field indicates whether or not the Switch can use loopback control PDUs to put the
remote device into loopback mode.
This field indicates whether or not the Switch can interpret link events, such as link fault
and dying gasp. Link events are sent in event notification PDUs and indicate when the
number of errors in a given interval (time, number of frames, number of symbols, or
number of errored frame seconds) exceeds a specified threshold. Organizations may
create organization-specific link event TLVs as well.
This field indicates whether or not the Switch can respond to requests for more
information, such as requests for Ethernet counters and statistics, about link events.
This field displays the maximum size of PDU for receipt and delivery.
This field indicates that the link is up or down.
This field displays the current version of local state and configuration. This two-octet
value starts at zero and increments every time the local state or configuration
changes.
