BT Voyager 2100/2110/2091 CLI

adsl bar


*Use caution when exploring the router CLI - you do so at your own risk.*

The BT Voyager 2100/2110/2091 all use the same/similar firmware and you can explore the contents of the CLI using the telnet command.

To open Telnet from the Start Menu > Run and type in "telnet".

This will open a new window type: open
Enter your login name (usually admin) and the password.

Voyager 2100 CLI

Main menu gives the following options

Main Menu

1. ADSL Link State
2. LAN
3. WAN
4. DNS Server
5. Route Setup
6. NAT
7. Firewall
8. Quality Of Service
9. Management
10. Passwords
11. Reset to Default
12. Save and Reboot
13. Exit

From here we can get some information that may not available from the web interface.

Voyager 2100 telnet

For example 1. ADSL Link State gives us a bit more information about our connection than the web interface such as the estimated Maximum speed of our line and a few other error reporting details

-> 1

Firmware CLI

The Voyager CLI firmware is remarkably similar to the USRobotic 9105 and many of the same commands are available.
You can see which commands are available by using the "help" command

-> help


To find sub commands use "<dir> --help" eg

-> adsl --help
Usage: adsl start [--up] [--mod <a|d|l|t|2|p|e|m>] [--lpair <(i)nner|(o)uter>]
[--trellis <on|off>] [--snr <snrQ4>] [--bitswap <on|off>] [--sra <on|off>]
adsl stop
adsl connection [--up] [--down] [--loopback] [--reverb]
[--medley] [--noretrain] [--L3] [--diagmode]
[--tones <xmtStart xmtNum xmtMap rcvStart rcvNum rcvMap>]
adsl configure [--mod <a|d|l|t|2|p|e|m>] [--lpair <(i)nner|(o)uter>]
[--trellis <on|off>] [--snr <snrQ4>] [--bitswap <on|off>] [--sra <on| off>]
adsl bert [--start <#seconds>] [--stop] [--show]
adsl info [--state] [--show] [--stats] [--SNR] [--QLN] [--Hlog] [--linedi ag] [--reset]
adsl adslstatus
adsl --version
adsl --help

So from this we could say get info about the connection

-> adsl info --show

-> adsl info --SNR
Gives us information about the Tone number (BIN) and the SNR value (more info).

More info can about the firmware commands can be obtained from the USR 9105 CLI manual which can be downloaded from the USR website.

BusyBox Shell commands

Using the command "sh" you can enter the linux BusyBox Shell to get further options

-> sh
BusyBox v0.60.4 (2006.03.27-01:43+0000) Built-in shell (msh)
Enter 'help' for a list of built-in commands.

By using the echo command we can see which directories are available

# echo *
bin dev etc lib linuxrc mnt proc sbin usr var webs

Contents of directories can also be viewed in a similar way

# echo proc/*
proc/1 proc/13 proc/2 proc/207 proc/215 proc/216 proc/222 proc/223 proc/227 proc
/3 proc/310 proc/315 proc/32285 proc/32375 proc/4 proc/48 proc/5 proc/6 proc/694
9 proc/7 proc/74 proc/8243 proc/8254 proc/8255 proc/bus proc/cmdline proc/cpuinf
o proc/devices proc/dma proc/driver proc/execdomains proc/filesystems proc/fs pr
oc/interrupts proc/iomem proc/ioports proc/irq proc/kcore proc/kmsg proc/ksyms p
roc/loadavg proc/locks proc/meminfo proc/misc proc/modules proc/mounts proc/mtd
proc/net proc/partitions proc/pptp proc/self proc/slabinfo proc/stat proc/swaps
proc/sys proc/sysvipc proc/tty proc/uptime proc/var proc/version

By combining the cat and proc command we can get certain info from the router.

# cat /proc/cpuinfo
system type : RTA770W
processor : 0
cpu model : BCM6345 V0.0
BogoMIPS : 92.97
wait instruction : no
microsecond timers : yes
tlb_entries : 32
extra interrupt vector : no
hardware watchpoint : no
VCED exceptions : not available
VCEI exceptions : not available
