metrobility-optical-syste radiance r231-49 User Manual

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.

Through SNMP management, NetBeacon or WebBeacon, you can view Remote
Monitoring (RMON) and Ethernet statistics for the Radiance access line card.

Each port on the card supports the complete RMON Group 1 statistics outlined
in RFC 1757 and listed below.

For the card’s fiber port, you can obtain the Ethernet statistics listed in the table
below. For a copper port, only the Port Link Status is reported.

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
