CentOS 8.x Zabbix add network switches for SNMP based monitoring

To add network switches for SNMP based monitoring use following steps:

Configure SNMP community public for read-only access at devices
```
config t
snmp-server community public ro
snmp-server server
```
If we use any other community name instead of public then modify default community string for all devices in Zabbix
For this go to Administration -> General and select Macros from drop down in top right corner
Optionally create host group for network devices
Add host to Zabbix with appropriate SNMP template. For example for Cisco try "Template Net Cisco IOS SNMPv2"
To get the host interfaces discovered quickly go to Configuration -> Hosts and click on switch name. Then go to discovery. Select all rules and choose "Check now" to get interfaces discovered immediately.
