Usage guidelines
If an Ethernet interface has a history control entry, RMON periodically samples packet statistics on
the interface and stores the samples to the history table. When the bucket size for the history control
entry is reached, RMON overwrites the oldest sample with the most recent sample.
You can create multiple history control entries for one interface, but you must make sure their entry
numbers and sampling intervals are different.
You can create a maximum number of 200 history control entries on a device. After the limit is
reached, you cannot add new entries.
You can create RMON history control entries only for Layer 2 and Layer 3 Ethernet interfaces.
Examples
# Create RMON history control entry 1 for FortyGigE 1/0/1.
<Sysname> system-view
[Sysname] interface fortygige 1/0/1

Parameters
entry

number
: Specifies a private alarm entry index in the range of 1 to 65535.
prialarm-formula
: Configures a private alarm variable formula, a string of 1 to 255 characters. The
variables in the formula must be represented in OID format that starts with a dot (.), for example,
(.1.3.6.1.2.1.2.1.10.1)*8. You can configure a formula to perform the basic math operations of
addition, subtraction, multiplication, and division on these variables. To ensure a correct calculation
result, the values of the variables in the formula must be positive integers, and the result of each
calculating step must be in the value range for long integers.
prialarm-des
: Configures an entry description, a case-sensitive string of 1 to 127 characters.
