I have an SNMP issue with the community name.

The default name is "public" . When I tried to change it to anther one, I find that I can walk the SNMP with two name "public" and "loreal" (giving the command snmpwalk) without apparent errors, like in lines below :

C:\>snmpwalk -v1 -c LOREAL 128.86.201.207 enterprises.683.3.3.0
SNMPv2-SMI::enterprises.683.3.3.0 = STRING: "LOREAL"

C:\>snmpwalk -v1 -c public 128.86.201.207 enterprises.683.3.3.0
SNMPv2-SMI::enterprises.683.3.3.0 = STRING: "LOREAL"

But when I use the command snmpSET, I can't use the new name ("LOREAL") to change value 

C:\>snmpset -v1 -c LOREAL 128.86.201.207 enterprises.683.3.3.0 s SWAT
Timeout: No Response from 128.86.201.207

C:\>snmpset -v1 -c public 128.86.201.207 enterprises.683.3.3.0 s SWAT
SNMPv2-SMI::enterprises.683.3.3.0 = STRING: "SWAT"

Why this happens, how can I definitively change or delete the "public" and use only "LOREAL" for the snmpset/get commands?

Notes:

  • the MIB tree for zebra printer
  • I change the community Name with ZPL II commands
  • my OS win10

I found solution for this issue, my problem was with the version firmware for this printers.

the model of printers is ZT230-200dpi ZPL and the version of firmware was V72.19.1Z

so when I try to change community Name with zpl commands , the commands were execute incorrectly.

I did upgrade the firmware to V72.20.1Z and I tried to send zpl commands

now I have response from SNMP get/set and I can change the values with the chosen community Name
