SNMP Objects used in Highlight
Overview
Highlight uses SNMP v1, v2c, or v3 to collect information. Please contact us for more detail on using SNMPv3 in Highlight.
Please note that the Objects list is summarised and not exhaustive. Due to intellectual property issues we cannot release the full list without a signed NDA. Please speak to your Account Manager.
MIB-2 Compliant devices
This document describes all Highlight functionality as it pertains to generic (MIB-2 compatible) devices, and some function-specific items for Cisco and Juniper devices. Some parallel functionality exists within the product for other vendors i.e. Zyxel and Lucent, and these equivalent OIDs are available on request.
Different sets of SNMP Objects are used for different Highlight features: note that Highlight requires READ ONLY access to these areas of the MIB.
| SNMP Object | Function |
|---|---|
| system | Basic system details |
| interfaces | Collect Traffic Statistics |
| ifMib | Interface structure, fullnames, high-capacity counters |
| transmission | Traffic / congestion, stats and line rates for DSL |
| cisco.local.lcpu | CPU Load on Cisco Devices |
| ciscoProcessMIB | CPU extended Load and Process info on Cisco Devices (if available) |
| jnxOperatingCpu | CPU Load on Juniper Devices |
Highlight Class of Service Monitoring
Highlight Class of Service discovers Classes associated with a policy attached to the interface being monitored (used for Quality of Service applications), and provides statistics on these streams of data. These variables are specific to Cisco QoS: note that Highlight requires READ ONLY access to this area of the MIB.
| SNMP Object | Function |
|---|---|
| ciscoCBQosMIB | Individual Class Definitions & statistics (traffic pre and post, drops, etc) |
Highlight Application Awareness functionality
Application Awareness uses Cisco Network-Based Application Recognition technology (NBAR): note that Highlight requires READ ONLY access to this area of the MIB.
| SNMP Object | Function |
|---|---|
| ciscoNbarProtocolDiscoveryMIB | Application statistics on the chosen interface |
Performance Analysis functionality
Performance Analysis uses the Cisco ipSLA or Juniper RPM features to create recurring performance tests. Test packets can be tagged with a given Type of Service (TOS) setting to measure performance for a given class of service across the network (i.e. mark the performance test so it ‘looks like’ a particular class of traffic) additionally a VRF marker can be added : note that Highlight requires READ WRITE access to these areas of the MIB.
| SNMP Object | Function |
|---|---|
| ciscoRttMonMib | Performance testing functionality on Cisco devices |
| pingMib, jnxPingMib | Performance testing functionality on Juniper devices |
ADSL Bandwidth Discovery functionality
Highlight dynamic bandwidth discovery uses two OIDs from the adslMIB : note that Highlight requires READ ONLY access to these areas of the MIB.
| SNMP Object | Function |
|---|---|
| adslAtucChanCurrTxRate | Inbound ADSL bandwidth |
| adslAturChanCurrTxRate | Outbound ADSL bandwidth |
