Creating An Rmon History Control Entry; Configuring The Rmon Alarm Function - HP 5920 Configuration Manual

Step
3. Create an entry for
the interface in the
RMON statistics
table.

Creating an RMON history control entry

You can configure multiple history control entries for one interface, but you must make sure their entry
numbers and sampling intervals are different.
You can create a history control entry successfully even if the specified bucket size exceeds the available
history table size. RMON will set the bucket size as closely to the expected bucket size as possible.
To create an RMON history control entry:
Step
1. Enter system view.
2. Enter Ethernet
interface view.
3. Create an entry for
the interface in the
RMON history
control table.

Configuring the RMON alarm function

When you configure the RMON alarm function, follow these guidelines:
• To send notifications to the NMS when an alarm is triggered, configure the SNMP agent as
described in
For a new event, alarm, or private alarm entry to be created:
•
The entry must not have the same set of parameters as an existing entry.
The maximum number of entries is not reached.
Table 17 shows the parameters to be compared for duplication and the entry limits.
