Diagnostic Parameters and Commands
Using diagnostics-related DO commands
A call is noted as “bad” if modem handshaking fails at any point in the initial call set-up, or if
the dial-in user does not successfully log in.
The
dir
parameter indicates the direction of the last call into each modem. It can have the
following settings:
1—Call direction unknown.
2—Call was outgoing.
3—Call was incoming.
A modem is moved to the suspect list if its first four calls are bad, or if it experiences eight bad
calls in a row. Modems on the suspect list can still be used if all free modems are in use. Any
subsequent successful call to a suspect modem places that modem back on the free list.
Note:
A call that has been categorized as bad does not necessarily indicate a modem problem
with the MAX unit. Poor line quality, software problems with the calling modem, wrong
numbers, and forgotten passwords all can generate calls that appear as bad calls but have
nothing to do with modems on the MAX unit.
Usage: Enter
lanport modem
at the command prompt.
Example: In the following display, an 8-mod modem card is located in slot 8 of the MAX
unit. Modems 8:5 and 8:6 are in use. Modems 8:2, 8:3, 8:4, 8:7, and 8:8 are idle and available
to accept calls. Modem 1 has been disabled by the V.34 Modem > Modem Diag > Modem #1
parameter.
> lanport modem
Modems on free list:
Modem 8:4, 70 calls, 6 bad, last 32 calls = ffdffbfc dir=3
Modem 8:8, 54 calls, 1 bad, last 32 calls = ffffffff dir=3
Modem 8:3, 63 calls, 1 bad, last 32 calls = fffbffff dir=3
Modem 8:2, 74 calls, 1 bad, last 32 calls = ffffffff dir=3
Modem 8:7, 64 calls, 2 bad, last 32 calls = ffbfffbf dir=3
Modems on suspect list:
Modem 8:1, 57 calls, 0 bad, last 32 calls = ffffff00 dir=3
Modems on disabled list:
Modems on dead list:
Modems on busy list:
Modem 8:5, 65 calls, 2 bad, last 32 calls = fffffffd dir=3
Modem 8:6, 58 calls, 1 bad, last 32 calls = ffffffff dir=3
Looking at modem 4 on slot 8 (designated 8:4), the eight-digit hexadecimal number has to be
converted to binary to indicate how many of the last 32 calls were successful:
ffdffbfc = 11111111110111111111101111111100
The zeroes show that modem 8:4 has had four unsuccessful calls, including the last two calls.
After the hexadecimal number,
dir=3
indicates that the last call was an incoming call.
Lcstate
Description: Displays the LANCORE state of incoming traffic processed on the MAX unit.
Usage: Enter
lcstate
at the command prompt.
