Radiance 10/100Mbps Access Optical Network Unit 15
Disabling a port stops the data flow to and from that port. Although data is
neither sent nor received, the disabled port continues to accept, process and
transmit management packets. However, if LLCF is enabled and the opposite
port has no link, management packets will not be transmitted.
Remote Management Statistics
Through SNMP management, NetBeacon or WebBeacon, you can view Remote
Monitoring (RMON) and Ethernet statistics for the Access ONU.
RMON Statistics
Each port on the Access ONU supports the complete RMON Group 1 statistics
outlined in RFC 1757 and listed below.

Ethernet Statistics
The Ethernet statistics listed in the table below are provided for the Access
ONU’s fiber port. For the copper port, only the Port Link Status is reported.
Statistic Name Description
Port Link Status Indicates whether or not the port has a valid link.
Link Transition Counter Number of times link was lost since power-up.
The value is 0 after the card is reset, even without a link.
Management Counter Number of management packets received.
Discovery Count Number of remote devices discovered on the network.
