I have transitioned some of the projects I am working on out to trusted lieutenants to make things more scalable. Still a very small focused team but that's a good thing.
I am now focusing on networking. Started by setting up a cisco 1841 integrated services router and a catalyst 2924 switch. Was relatively easy and excellent documentation (both tutorial and reference) was available. Of course it helped that I knew what I wanted to do (NAT/port forwarding/dhcp client). If you don't have a basic understanding of networking and some solid end goals (preferably following the MGOT methodology I have created or something similar) you'll end up in the deep end very quickly.
Ok. So I have an ADSL connection from AT&T (or SBC as many of you may be familiar with).
My modem is a Motorola Netopia 2210-02 ADSL Modem. Its rather boring. It's a layer2 device more or less with a very simple management interface.
I looked at the technician readout from it, and am researching it. Here is the readout with lots of links/comments etc:
Some basic stuff:
1 Manufacturer Motorola, Inc.
2 Vendor ID 001d6b
3 Model Number 2210-02
4 Friendly Name Motorola Netopia 2210-02 ADSL Modem
5 Model Description Single Port Ethernet Modem
6 Model Name 2210-02
7 Serial Number 41080152
8 Hardware Version 1.0
9 Model DSL Firmware Version DSP 7.2.3.0, HAL 7.2.1.0
10 Model Software Version 7.7.3r5
11 Hardware Options
12 Software Options
13 Modem Configured true
Online manual for the modem can be found at broadband.motorola.com/consumers/
Not much there. Just basic config info.
Some basic stats:
14 Time Since Last Boot 013 days 15:28:45
15 Current Time 2008/06/11 21:32:16 GMT
16 Time Servers 68.94.156.17
68.94.157.2 ntp1.sbcglobal.net
ntp2.sbcglobal.net
17 First Time Use 2008/05/28 15:32:06 GMT
30 Modem Health Status ok
31 DSL Link Status up
32 Time Since Last Sync 000 days 20:26:23
33 Loss of Signal false
34 Loss of Framing false
First item of interest to me:
35 ATM Cell Delineation true
What is ATM Cell Delineation? Wow.... no wikipedia article. Interesting.
One reference here: http://www.cisco.com/en/US/tech/tk39/tk49/technologies_tech_note09186a00800d73b7.shtml
Protocol overview here:
http://www.javvin.com/protocolATM.html
Interesting. Not much to go on.
36 Internet Status up
37 Ethernet Link Status up
38 PPP Connection Status connected
39 PPP Last Connection Error none
40 PPP Uptime 000 days 20:26:40
50 Test ADSL Line Sync pass
51 Test ATM Cell Delineation pass
52 Test ATM Signal pass
More interesting stuff:
53 Test ATM OAM Segment Ping pass
54 Test ATM OAM End to End Ping pass
Paydirt on OAM: http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/12satmpng.html (Stands for Operation, Administration, and Maintenance).
The ATM OAM Ping feature sends an ATM Operation, Administration, and Maintenance (OAM) packet to confirm the connectivity of a specific permanent virtual circuit (PVC). The status of the PVC is displayed when a response to the OAM packet is received. The ATM OAM Ping feature allows the network administrator to verify PVC integrity and facilitates ATM network troubleshooting.
Cool. PVC will be used later on in this post. So remember what it stands for.
55 Test DSL Ethernet to ATM pass
56 Test LAN Ethernet Connection pass
57 Test Mac Bridge to LAN Ethernet pass
60 Test PPPoE to Ethernet pass
61 Test PPP to PPPoE pass
62 Test PPPoE Server Connect pass
63 Test PPPoE Server Session pass
64 Test Authentication with PPP server pass
I presume that 62 to 64 are related to the DSLAM/Radius server....
65 Test IP to WAN pass
66 Test IP to LAN Ethernet pass
68 Test IP to PPP pass
69 Test Validate WAN IP address pass
70 Test Gateway Ping pass
71 Test DNS Well Known Host Query pass
72 Test Primary DNS Ping pass
73 Test Secondary DNS Ping pass
74 Test Mail Srvr 1 Ping skipped
75 Test Mail Srvr 2 Ping skipped
76 Test News Srvr 1 Ping skipped
77 Test News Srvr 2 Ping skipped
78 Test Web Portal 1 Ping skipped
79 Test Web Portal 2 Ping skipped
80 Test PPPoE Connect to Gateway pass
Ok. So a healthy overall connection. A bit of research needed to figure everything out and I'm mostly satisifed. :)
90 Active VCs provisioned 1
Hmmm.... interesting. Wonder if there is a way to get more then one active VC provisioned..... probably not over the same copper/fiber (PON) circuit but who knows?
91 DSLAM Vendor Id 4244434d (BDCM)
So 91 is interesting. A quick search reveals some tables with various DSLAM vendor IDs. This one is a broadcom. See http://www.broadcom.com/products/applications/DSLAMs for more on their offerings.
92 DSL Line Mode DMT
93 DSL Training Mode multimode
Hmmmm..... line mode and training mode.... very interesting.
Lots of tech readouts but nothing explaining what DSL line mode actually is. Also some hits on vendor manuals for the term as well.
How bout training mode? More or less the same type results as line mode.
94 Conf VPI 0
95 Conf VCI 35
96 Conf PVC Search List 0/35, 8/35, 0/43, 0/51, 0/59, 8/43, 8/51, 8/59
97 VPI 0
98 VCI 35
99 VC Encapsulation LLC
So 94 to 99 is interesting. See http://www.tekelec.com/ss7/protocols/atm10.asp for more info. Searching for atm vpi or atm vci returns lots of results.

Good technical blog article. Please post the same article to the site: http://www.networkdictionary.com

I went to the ip on the bottom of my modem same as the one of his readouts. Instead it went to my modem acount were i can manage it. Even download upgrades for software and check status and other things. Logs can be erased to.
did you ever find out how to turn on the NAT firewall. mine also says disabled. i did NOT run the CD (and hope never to have to)- is that the only way to turn it on, perhaps?
thanks
