I’ve just got SNMP working on my Thomson SpeedTouch 510 ADSL router, so I can better
monitor my bandwidth in order to decide whether to move from a 512 unlimited account
to a Max DSL 20GB capped one.
For the benefit of future googlers, here are some solutions to issues
I ran into:
1) I’m running the latest 4.3.2.6.0 firmware – I upgrading in the hope
that it might support multicast, but I haven’t had any success with
it.
2) The username you log in as with this firmware is « Administrator ».
3) You need to turn on the SNMP client
telnet to the router,
then service = system = list
….
13 SNMP_AGENT udp 161 disabled
….
enable it
| {Administrator}[service system]=modify
| name = SNMP_AGENT
| [state] = enabled
| [log] =
6) Set community names – RO = public and RW = private:
snmp = community
{Administrator}[snmp community]=modify
securityname = ROCommunity
communityname = public
Please retype communityname for verification.
communityname = public
:snmp community modify securityname=ROCommunity communityname=_DEV_435BF38718FA44D1
{Administrator}[snmp community]=modify
securityname = RWCommunity
communityname = private
Please retype communityname for verification.
communityname = private
:snmp community modify securityname=RWCommunity communityname=_DEV_8F162D13A059CB2D
Then save the config
{Administrator}=config
{Administrator}[config]=save
filename = user
:config save filename=user
5) I have the router configured not to do NAT – I need to address the
router with its internal address – if I use the external address it
replies with the internal one:
# tcpdump -n -vv -i eth1 udp port 161
tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 68 bytes
