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

1. Configure SNMP community public for read-only access at devices

   config t
   snmp-server community public ro
   snmp-server server

2. 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

3. Optionally create host group for network devices
4. Add host to Zabbix with appropriate SNMP template. For example for Cisco try "Template Net Cisco IOS SNMPv2"
5. 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.
