5.5.11.2.1 Modem

This command is useful for interrogating the quality of connection of a particular user.

The modem command is available once you login as superuser. It is best to first use the

who command and determine the user you are interested in. The users identification will

be the asy number. For example a user amcacct is using asy35 can be queried by typing:

annex# modem -s35

asy30 States: loader 0, protocol 5, link 5, control 10, pump 0xff

Error correction 5 (V.42), compression 0 (none)

Drops: from 0, to 0; HDLC under 0, over 0; event 48

Rcv: errs 0, pkts 200; Tx resent 80, pkts 143

Rrn: rcvd 0, init 0; train rcvd 0, init 0, disc 0 (unknown)

V.34 rx precoding 0, non-linear 0, shaping 0, carrier 0, pre-emphasis 0

X2 status 0x7, RBS 0, PAD 0, speed reduction 0 (0 kb)

K56flex ver 0 (none), status 0xff, RBS 0, PAD 0, speed reduction 0 kb

V.90 status 0x14bf, c.i. 0x12345, PAD 0, shaping 1

V.90 lookahead 0, c.pwr -12 dBm, half duplex RRN rx 0

Delay 7ms, snr 32dB, qual 0, chan freq 0Hz

Echo offs 90Hz, lvl -34dBm; osc freq 15PPM; Rcv lvl -22dBm

Baud rx 4 (3200), tx 6 (8000); speed rx 14 (26400), tx 25 (29333)

Connect status 3 (connected), modulation 6 (V.90)

As you can see the modem command provides extensive information on the characteris-

tics of the modem connection. This information can be very useful in verifying and trou-

bleshooting a customers modem problems.

See Section 1 of the “Remote Access Concentrator Software Reference for more Detail.

5.5.11.2.2 Netstat

Netstat is a very useful command. It can be confusing since it has 30 options. I wish to

cover a couple of the more useful commands. Refer to Bay Publication “Managing

Remote Access Concentrators Using Command Line Interface” section 16 for a complete

list.

5.5.11.2.3 PPP Statistics (netstat -ip)

Netstat -ip displays the connection parameters associated with the PPP session. It can be

used for both synchronous connections (ISDN) and asynchronous connections (analog

Note: User names will not show up, unless you have the appropriate

security turned on. For example for PPP names, PPP security must

be enabled.
