• You can configure multiple history control entries for one interface, but must make sure their entry
numbers and sampling intervals are different.
• The device supports up to 100 history control entries.
• You can successfully create a history control entry, even if the specified bucket size exceeds the
history table size supported by the device. However, the effective bucket size will be the actual value
supported by the device.
To configure the RMON history statistics function:
Step Command
1. Enter system view. system-view
2. Enter Layer 2 Ethernet interface view. interface interface-type interface-number
3. Create an entry in the RMON history
control table.

Configuring the RMON alarm function
Follow these guidelines when you configure the RMON alarm function:
• To send traps to the NMS when an alarm is triggered, configure the SNMP agent as described in
"Configuring SNMP."
• If the alarm variable is a MIB variable defined in the history group or the Ethernet statistics group,
make sure the RMON Ethernet statistics function or the RMON history statistics function is
configured on the monitored Ethernet interface. Otherwise, even if you can create the alarm entry,
no alarm event can be triggered.
• You cannot create a new event, alarm, or private alarm entry that has the same set of parameters
as an existing entry. For parameters to be compared for duplication, see
Table 8 .
• After the maximum number of entries is reached, no new entry can be created. For the table entry
limits, see
Table 8 .
To configure the RMON alarm function:
