By default, no RMON history control
entries exist.
You can create multiple RMON history
control entries for an Ethernet interface.
You can create a maximum of 200
RMON history control entries on a
device. When the limit is reached, you
cannot add new entries.
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 "Configuring SNMP" before config
uring the RMON alarm function.
• 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.
