MIB: EtherLike-MIB

The current mode of operation of the MAC

entity. 'unknown' indicates that the current

duplex mode could not be determined.

Management control of the duplex mode is

accomplished through the MAU MIB. When

an interface does not support autonegotiation,

or when autonegotiation is not enabled, the

duplex mode is controlled using

ifMauDefaultType. When autonegotiation is

supported and enabled, duplex mode is controlled

using ifMauAutoNegAdvertisedBits. In either

case, the currently operating duplex mode is

reflected both in this object and in ifMauType.

Note that this object provides redundant

information with ifMauType. Normally, redundant

determine the duplex status of an interface

without having to know every possible value of

ifMauType. This was felt to be sufficiently

valuable to justify the redundancy.

This trigger expression works as follows:
1. It can be triggered if the operations status is down.
2. {$IFCONTROL:"{#IFNAME}"}=1 - a user can redefine context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.
3. {TEMPLATE_NAME:METRIC.diff()}=1 - the trigger fires only if the operational status was up to (1) sometime before (so, do not fire for the 'eternal off' interfaces.)

WARNING: if closed manually - it will not fire again on the next poll, because of .diff.

The utilization of the network interface is close to its estimated maximum bandwidth.

Discovering interfaces from IF-MIB and EtherLike-MIB. Interfaces with up(1) Operational Status are discovered.

Preprocessing

• JavaScript: The text is too long. Please see the template.

MIB: EtherLike-MIB

The current mode of operation of the MAC

entity. 'unknown' indicates that the current

duplex mode could not be determined.

Management control of the duplex mode is

accomplished through the MAU MIB. When

an interface does not support autonegotiation,

or when autonegotiation is not enabled, the

duplex mode is controlled using

ifMauDefaultType. When autonegotiation is

supported and enabled, duplex mode is controlled

using ifMauAutoNegAdvertisedBits. In either

case, the currently operating duplex mode is

reflected both in this object and in ifMauType.

Note that this object provides redundant

information with ifMauType. Normally, redundant

objects are discouraged. However, in this

instance, it allows a management application to

determine the duplex status of an interface

without having to know every possible value of

ifMauType. This was felt to be sufficiently

valuable to justify the redundancy.

This trigger expression works as follows:

1. Can be triggered if operations status is down.

2. {$IFCONTROL:"{#IFNAME}"}=1 - user can redefine Context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.

3. {TEMPLATE_NAME:METRIC.diff()}=1) - trigger fires only if operational status was up(1) sometime before. (So, do not fire 'ethernal off' interfaces.)

Discovering interfaces from IF-MIB.

MIB: IF-MIB

The current operational state of the interface.

- The testing(3) state indicates that no operational packet scan be passed

- If ifAdminStatus is down(2) then ifOperStatus should be down(2)

- If ifAdminStatus is changed to up(1) then ifOperStatus should change to up(1) if the interface is ready to transmit and receive network traffic

- It should change todormant(5) if the interface is waiting for external actions (such as a serial line waiting for an incoming connection)

- It should remain in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state

- It should remain in the notPresent(6) state if the interface has missing(typically, hardware) components.
