Recently, I emulate an firewall (asav9121) in GNS3 with the latest asav9-12-1.qcow2 image. When getting information from device with SNMP protocol, I always get no response with snmp version v2c. It works well with snmp version v1.
gns3@gns3vm:~$ snmpwalk -v1 -c public 192.168.110.99 .1.3.6.1.2.1.1.1 iso.3.6.1.2.1.1.1.0 = STRING: "Cisco Adaptive Security Appliance Version 9.12(1)" gns3@gns3vm:~$ snmpwalk -v2c -c public 192.168.110.99 .1.3.6.1.2.1.1.1 Timeout: No Response from 192.168.110.99
Also, I have tested this in asav9101.qcow2. It works well.
gns3@gns3vm:~$ snmpwalk -v1 -c public 192.168.110.99 .1.3.6.1.2.1.1.1 iso.3.6.1.2.1.1.1.0 = STRING: "Cisco Adaptive Security Appliance Version 9.10(1)" gns3@gns3vm:~$ snmpwalk -v2c -c public 192.168.110.99 .1.3.6.1.2.1.1.1 iso.3.6.1.2.1.1.1.0 = STRING: "Cisco Adaptive Security Appliance Version 9.10(1)"
The snmp-server configurations in these two devices are same.
asav9121# show running-config | in snmp snmp-server host outside 192.168.110.1 community ***** snmp-server location aaaa snmp-server contact 1111 snmp-server community *****
So what else should I do to make it work with snmp version v2c in asav9-12-1.qcow2?
Thanks! Any help would be appreciated!

- You are least very ambitious to expect that these virtual implementations on GNS3 would fully offer all SNMP services from the real world box. I doubt it.

Thanks for your reply.
In my opinion, it should support both snmp v1 and v2c, for it's a basic capability. I have emulated other devices such as asav962, asav981, asav992 and asav9101 on GNS3, all of which support that. As to the asav9121, it was released two weeks ago. So I am not sure what new features have been added about SNMP. I got nothing useful from its release notes.
