SNMP syntax question

Hello,

I need to create an snmp.comf file that defines 2 IPs to the same community string.
Do I need to have 2 community strings with the same name and diff't IPs?
Or should I have 1 string and list the IPs? (comma seperated?)

Example:

rocommunity EC_8000_RO

arguments EC_8000_RO 192.xx.xx.1 10.xx.xx.2

rwcommunity EC_8000_RW 

arguments EC_8000_RW 192.xx.xx.1 10.xx.xx.2

#EC_8000_RO EC_8000_RW 192.xx.xx.1 10.xx.xx.2

I found this helper;

Man Page for snmpconf (All Section 1) - The UNIX and Linux Forums

Thanks

I've seen that before and I dont feel like it fully answers my question
