ES-1528 User’s Guide

SNMP communities are used to define the security parameters of SNMP clients in an SNMP 
v1 and SNMP v2c environments. The default SNMP community is “public” for both SNMP 
v1 and SNMP v2c before SNMP v3 is enabled. Once SNMP v3 is enabled, the communities of 
SNMP v1 and v2c have to be unique and cannot be shared. Use the SNMP Community 
screen to create SNMP communities and associate SNMP groups to them. Click SNMP > 
Community to view the screen as shown.
