Usage Guidelines

This command displays selected WAN PHY OAM overhead for the specified WAN PHY ports. The overhead number comes directly from the WAN PHY framing; for each overhead, both transmit and receive numbers are displayed.



Overhead values display in hexadecimal format.

If you do not specify a port number, range of ports, or tag value, the errors are displayed for all WAN PHY ports. The default display is a constantly refreshing real-time display. If you specify the no-refresh parameter, the system displays a snapshot of the data at the time you issue the command.

The tag value may be associated with either a VMAN or a VLAN.
