SNMP configuration on CISCO routers with IOS older then 12.2
I have some problem. I configured several snmp commands on router with IOS 12.3(5d). I tried it on CISCO 1701 and Cisco 2621XM. These are the commands:
snmp-server community test1 RO 10
snmp-server community test2 RW 11
access-list 10 permit 10.10.10.10
access-list 11 permit 10.10.10.10
Then I try to make snmp request to this router using some ip tool from computer with ip 10.20.20.20 (for example) and i get response from the router. It doesn't matter what is the response the most important is that I get response. When I used IOS 12.4 (7) I had got the same response. But when I used 12.2 version, router did not reply to my snmp packets - and I think it should be the right behaviour. Anyway may be it is new IOS feature - to reply to the PC's snmp request though it's ip is not allowed in access-lists. Could you help me and clarify this. Thanks in advance.
