Parameter
entry - number : History entry index, in the range of 1 to 65535.
buckets number : Specifies the size of the history table that corresponds to the entry, in
the range of 1 to 65535. Currently the device only supports 1 to 10. If you enter an
argument greater than 10, the actual table size is still 10.
interval sampling - interval : Specifies the sampling interval (in seconds). The
sampling-interval argument ranges from 5 to 3,600.
owner text : Specifies the owner of the entry, a string comprising 1 to 127 characters.
Description
Use the rmon history command to add an entry to a history control table.
Use the undo rmon history command to delete an entry from a history control table.
You can use the rmon history command to sample a specific port. You can also set the
sampling interval and the number of the samples that can be saved. After you execute
this command, the RMON system samples the port periodically and stores the samples
for later retrieval. The sampled information includes utilization, the number of errors,
and total number of packets.
You can use the display rmon history command to display the statistics of the history
control table.
Example
# Create the history entry numbered 1 for Ethernet1/0/1 port, with the table size being
