|
|
### Known Issues
|
|
|
- Description: no IF-MIB::ifAlias is available
|
|
|
- version: v6.3.1c, v7.0.0c, v7.4.1c
|
|
|
|
|
|
## Requirements
|
|
|
|
|
|
Zabbix version: 7.0 and higher.
|
|
|
|
|
|
## Tested versions
|
|
|
|
|
|
This template has been tested on:
|
|
|
- Brocade 6520 v7.4.1c
|
|
|
- Brocade 300 v7.0.0c
|
|
|
- Brocade BL 5480 v6.3.1c
|
|
|
|
|
|
## 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.
