|
|
|
|
|
## Overview
|
|
|
|
|
|
### Known Issues
|
|
|
|
|
|
Description: no if(in|out)(Errors|Discards) are available for vlan ifType
|
|
|
Version: IOS for example: 12.1(22)EA11, 15.4(3)M2
|
|
|
Device: C2911, C7600
|
|
|
|
|
|
## Requirements
|
|
|
|
|
|

|
|
|
|
|
|
## Tested versions
|
|
|
|
|
|
This template has been tested on:

|
- Cisco IOS Software releases 12.2(3.5)
|
|
|
|
|
|
## Configuration
|
|
|
|
|
|
> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.
|
|
|
|
|
|
## Setup

# Cisco IOS versions 12.0_3_T-12.2_3.5 by SNMP
|
|
|
|
|
|
## Overview
|
|
|
|
|
|
This template is designed for the effortless deployment of Cisco IOS versions 12.0_3_T-12.2_3.5 monitoring by Zabbix via SNMP and doesn't require any external scripts.
|
|
|
|
|
|
## Requirements
|
|
|
|
|
|
Zabbix version: 7.0 and higher.
|
|
|
|
|
|
## Tested versions
|
|
|
|
|
|
This template has been tested on:
|
|
|
- Cisco IOS Software releases later to 12.0(3)T and prior to 12.2(3.5)
|
|
|
|
|
|
## Configuration
|
|
|
|
|
|
> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.
|
|
|
|
|
|
## Setup
|
|
|
|
|
|
Refer to the vendor documentation.

# Cisco IOS prior to 12.0_3_T by SNMP
|
|
|
|
|
|
## Overview
|
|
|
|
|
|
This template is designed for the effortless deployment of Cisco IOS prior to 12.0_3_T monitoring by Zabbix via SNMP and doesn't require any external scripts.
|
|
|
|
|
|
## Requirements
|
|
|
|
|
|
Zabbix version: 7.0 and higher.
|
|
|
|
|
|
## Tested versions
|
|
|
|
|
|
This template has been tested on:
|
|
|
- Cisco IOS Software releases prior to 12.0(3)T
|
|
|
|
|
|
## Configuration
|
|
|
|
|
|
> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.
|
|
|
|
|
|
## Setup
|
|
|
|
|
|
Refer to the vendor documentation.
|
|
|
