Extreme EXOS by SNMP

Overview

ExtremeXOS is the software or the network operating system used in newer Extreme Networks network switches. It is Extreme Networks second generation operating system after the VxWorks based ExtremeWare operating system. ExtremeXOS is based on the Linux kernel and BusyBox.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • Extreme EXOS

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Refer to the vendor documentation.

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.

MIB: IF-MIB

The total number of octets received on the interface, including framing characters. This object is a 64-bit version of ifInOctets. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.

Interface {#IFNAME}({#IFALIAS}): Speed

MIB: IF-MIB

An estimate of the interface's current bandwidth in units of 1,000,000 bits per second. If this object reports a value of n' then the speed of the interface is somewhere in the range of n-500,000' to`n+499,999'. For interfaces which do not vary in bandwidth or for those where no accurate estimation can be made, this object should contain the nominal bandwidth. For a sub-layer which has no concept of bandwidth, this object should be zero.

Interface {#IFNAME}({#IFALIAS}): Link down

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.

Preprocessing

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

Item prototypes for EtherLike-MIB Discovery

Name Description Type Key and additional info
Interface {#IFNAME}({#IFALIAS}): Duplex status

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.
