SWITCH CONFIGURATION — SNMP v2c

NetPol uses SNMP v2c to poll your switches. Enable it on each Cisco switch:

snmp-server community YOUR_COMMUNITY_STRING RO
snmp-server location Your Site Name
snmp-server contact your@email.com

Replace YOUR_COMMUNITY_STRING with your chosen community string. Use the same string when adding switches in NetPol.
