This example looks at the number of OAM packets transferred on port 1.
Info. revision 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.
Parser state This field indicates the current state of the parser.
Forward: The packet is forwarding packets normally.
Loopback: The Switch is in loopback mode.
Discard: The Switch is discarding non-OAMPDUs because it is trying to or
has put the remote device into loopback mode.
Discovery state This field indicates the state in the OAM discovery process. OAM-enabled
devices use this process to detect each other and to exchange information
about their OAM configuration and capabilities. OAM discovery is a
handshake protocol.
Fault: One of the devices is transmitting OAM PDUs with link fault
information, or the interface is not operational.
Active Send Local: The Switch is in active mode and is trying to see if the
remote device supports OAM.
Passive Wait: The Switch is in passive mode and is waiting for the remote
device to begin OAM discovery.
Send Local Remote: This state occurs in the following circumstances.
•
The Switch has discovered the remote device but has not accepted or
rejected the connection yet.
• The Switch has discovered the remote device and rejected the
connection.
Send Local Remote OK: The Switch has discovered the remote device
and has accepted the connection. In addition, the remote device has not
accepted or rejected the connection yet, or the remote device has rejected
the connected.
Send Any: The Switch and the remote device have accepted the
connection. This is the operating state for OAM links that are fully
operational.
