Parameters
interface-type interface-number: Specifies an interface by its type and number. If you do not specify
an interface, the command displays history samples for all interfaces that have an RMON history
control entry.
Usage guidelines
RMON uses the etherHistoryTable object to store the history samples of Ethernet statistics for
Ethernet interfaces.
To collect history samples for an Ethernet interface, you must first create a history control entry on
the interface.
To configure the number of history samples that can be displayed and the history sampling interval,
use the rmon history command.
Examples
# Display the RMON history control entry and history samples for GigabitEthernet 1/0/1.
<Sysname> display rmon history gigabitethernet 1/0/1
HistoryControlEntry 6 owned by user1 is VALID.
Sampled interface : GigabitEthernet1/0/1<ifIndex.117>
Sampling interval : 8(sec) with 3 buckets max
Sampling record 1 :
dropevents : 0 , octets : 5869
packets : 54 , broadcast packets : 9
multicast packets : 23 , CRC alignment errors : 0
undersize packets : 0 , oversize packets : 0
fragments : 0 , jabbers : 0
