RMON Statistics Screen
10-10 Device Statistics Menu Screens
Table 10-4 RMON Statistics Screen Field Descriptions
Use this field… To
RMON Index
(Read-Only) See the current Ethernet interface for which statistics are being shown.
The SmartSwitch device has an embedded RMON agent that gathers
statistics for each interface on the device.
Data Source
(Read-Only) See the source of the statistics data that is currently being displayed on
the screen. Figure 10-4 shows that the data source for this RMON
index is Port 1 by displaying the name IfIndex.1. If the screen was
displaying RMON statistics for Port 4, the name displayed would be
IfIndex.4.
Owner
(Read-Only) See the name of the entity that configured this entry.
Status
(Read-Only) See the current operating status of the displayed interface. This field
displays “valid” or “invalid”.
Drop Events
(Read-Only) See the total number of times that the RMON agent was forced to
discard frames due to the lack of available switch resources.
NOTE: The Drop Events field does not display the number of
frames dropped, it only displays the number of times that the
RMON agent was forced to discard frames.
Collisions
(Read-Only) See the total number of collisions that have occurred on this interface.
Broadcast Pkts
(Read-Only) See the total number of good frames that were directed to the broadcast
address. The value of this field does not include multicast frames.
Multicast Pkts
(Read-Only) See the total number of good frames received that were directed to a
multicast address. The value of this field does not include frames
directed to the broadcast address.
CRC Align Errors
(Read-Only) See the number of frames with bad Cyclic Redundancy Checks (CRC)
received from the network. The CRC is a 4-byte field in the data frame
that ensures that the data received is the same as the data that was
originally sent.
Undersized Pkts
(Read-Only) See the number of frames received whose size was less than the
minimum Ethernet frame size of 64 bytes, not including preamble, but
have a valid CRC.
