2318 CHAPTER 153: RMON CONFIGURATION COMMANDS
Description Use the display rmon history command to display RMON history control entry
and last history sampling information, including bandwidth utilization, number of
bad packets, and total packet number.
Related command: rmon history.
Example # Display RMON history entry information for interface Ethernet 1/0.
<Sysname> display rmon history ethernet 1/0
History control entry 1 owned by user1 is VALID
Samples interface : Ethernet1/0<ifEntry.642>
Sampling interval : 10(sec) with 10 buckets max
Latest sampled values :
Dropevents :0 , octets :0
packets :0 , broadcast packets :0
multicast packets :0 , CRC alignment errors :0
undersize packets :0 , oversize packets :0
fragments :0 , jabbers :0
collisions :0 , utilization :0
Table 611 Description on the fields of the display rmon history command
Field Description
History control entry Index of the history control entry for the interface, 1 in this
example
owned by Owner of the entry
VALID Status of the entry identified by the index (VALID means the entry
is valid, and UNDERCREATION means invalid. You can use the
display rmon command to view the invalid entry and with the
display current-configuration and display this commands you
cannot view the corresponding rmon commands.)
Samples Interface The sampled interface
Sampling interval Sampling interval
buckets max History table size for the entry, if the specified value of the
buckets argument exceeds the history table size supported by
the device the latter is displayed.
Latest sampled values The latest sampled values
Dropevents Dropped packets during the sampling period
octets The number of octets received during the sampling period
packets The number of packets received during the sampling period
broadcastpackets The number of broadcasts received during the sampling period
multicastpackets The number of multicasts received during the sampling period
CRC alignment errors The number of packets received with CRC alignment errors
during the sampling period
undersize packets The number of undersize packets received during the sampling
period
oversize packets The number of oversize packets received during the sampling
period
fragments The number of fragments received during the sampling period
jabbers The number of jabbers received during the sampling period. (The
support for the field varies with devices.)
collisions The number of colliding packets received during the sampling
period
