Managing RMON Statistics

Cisco Small Business 200 Series Smart Switch Administration Guide 15

• Collisions—Number of collisions received. If Jumbo Frames are enabled, the

threshold of Jabber Frames is raised to the maximum size of Jumbo Frames.

• Frames of 64 Bytes—Number of frames, containing 64 bytes that were

received.

• Frames of 65 to 127 Bytes—Number of frames, containing 65-127 bytes

that were received.

• Frames of 128 to 255 Bytes—Number of frames, containing 128-255 bytes

that were received.

• Frames of 256 to 511 Bytes—Number of frames, containing 256-511 bytes

that were received.

• Frames of 512 to 1023 Bytes—Number of frames, containing 512-1023

bytes that were received.

• Frames greater than 1024 Bytes—Number of frames, containing 1024-

1632 bytes, and Jumbo Frames, that were received.

STEP 4 Select another interface in the Interface field. The RMON statistics are displayed.

- Log (Event Log Table)—Add a log entry to the Event Log table when the

alarm goes off.

- Trap(Syslog Ser ver)—Send a trap to the remote log server when the

alarm goes off.

- Log and Trap—Add a log entry to the Event Log table and send a trap to

the remote log server when the alarm goes off.

RMON alarms provide a mechanism for setting thresholds and sampling intervals.

Exception events can be generated on remote log servers maintained by the

agent. Both the rising and falling thresholds must be configured in the alarm. After

a rising threshold is crossed, another rising event is not generated until the

companion falling threshold is crossed. After a falling alarm is issued, the next

alarm is issued when the rising threshold is crossed.
