Linux smpwalk tool reports timeout querying Cisco 877 DSL router

I am trying to set up Cacti to plot the ADSL values for investigation of systematic dropped carrier.

What am I doing wrong?


In IOS:

#sh run | inc snmp

access-list 11 permit 10.10.10.3
access-list 100 permit udp 10.10.10.0 0.0.0.255 host 10.10.10.1 eq snmp

snmp-server community secretword RO 11

snmp-server community public RO

snmp-server host 10.10.10.3 secretword


In Linux console:

$ snmpwalk -v1 -c secretword 10.10.10.1
Timeout: No Response from 10.10.10.1

$ ifconfig eth0 : 0
eth0 : 0    Link encap:Ethernet  HWaddr 6C:F0:49:E3:0E:A7 
          inet addr:10.10.10.3  Bcast:10.10.10.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          Interrupt:31 Base address:0x8000

There's nothing wrong with the config snippets you provide, but this doesn't show the whole picture.  How is ACL 100 applied?  What other ACLs are on this router?  Is the router otherwise reachable from the NMS (e.g. ping, telnet, SSH, etc.)?  Is there a host-based firewall on this Linux host that is blocking outgoing or incoming udp/161 traffic?  Post the output of "show snmp" from the router.

Apparently I can ping and ssh into the router. There are no firewalls anywhere in this infrastructure.

Please post the "show snmp" output as well as the full config (less credentials) if you can.

public community works though. As I don't have time for this I'll simply give up.
