olPortAlertFilter

Module: CHIPCOMMIB

OID (symbolic): CHIPCOMMIB::olPortAlertFilter

OID (numeric): 1.3.6.1.4.1.49.2.3.1.4.2.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Enabling this object for a port will allow the

generation of port up (or port down) traps for port status

transitions caused by end stations powering up (or down).

Disabling this object will suppress the generation of port up

(or port down) traps for a port.

Note that this object is used in the trap generation decision

only if chipAlertMode, an object in chipAlertTable, is set

to filter(3).

Some ports, such as integrated bridge or router ports

do not support this feature. A getRequest on one of these

types of ports will return a value of other(3), and a

setRequest to enable(1) or disable(2) will return

the invalidData object.

What is olPortAlertFilter?

A read-write switch that enables or disables generation of port-up/port-down traps caused by end stations powering on or off for this port.
