Help Error Analysis 11/15/93
≤Counters:≥
For each station the number of
- all sent packets,
- correct packets,
- error packets,
- too long packets (more than 1514 bytes without
preamble and CRC),
- packets with collision,
- packets mit wrong CRC and
- packets with alignment error (dribble-error).
is shown.
It is possible, that an error packet has more than one of the
errors above (long, collision, CRC or dribble). That means that
the number of error packets must not be the sum of the packtets
in the individual error classes.
All counters are incremented permanently. To ⌠reset⌡ them use ⌠<F2>⌡.
≤Commands:≥
≤Switching Screens:≥
⌠<F5>⌡ or ⌠<B>⌡ - Switch between the lists of known and new
and ⌠<N>⌡ addresses. This is only possible, if the new
address-mode is activated:
⌠<Alt>-<F5>⌡ - Activate new address-mode.
⌠<F6> bzw. ⌠<P>⌡ - Switch between absolute values and percentage
values.
⌠<F7>⌡/⌠<F8>⌡
bzw. ⌠#026⌡/⌠#027⌡ - Sort entries:
┌── for hardwareaddresses #017──┐
└──#016 the number of all sent packets │
└──#016 the number of correct packets │
└──#016 the number of error packets │
└──#016 the number of too long packets │
└──#016 the number of collision packets │
└──#016 the number of CRC errors │
└──#016 the number of dribble errors ───┘
≤Orientation in the address lists:≥
By ⌠#024⌡, ⌠#025⌡, ⌠<PgUp>⌡, ⌠<PgDn>⌡, ⌠<Home>⌡ und ⌠<End>⌡
or by the ⌠<S>⌡earch-command:
Input (a part of) a hardwareadress or a station name to search for.
≤Receiver mode of the Ethernet Box: ≥
If the net traffic is too intensive to analyse, or if you are
interested only in special classes of errors, you can program
the box to monitor only a specified class of ethernet packets.
This is done by programming the receiver mode.
Command: Toggle receiving of:
-------- --------------------
⌠<G>⌡ - Correct packets.
⌠<L>⌡ - Too long packets.
⌠<O>⌡ - Collision packets.
⌠<C>⌡ - Packets with CRC errors.
⌠<D>⌡ - Packets with dribble errors.
The programmed receiver mode is shown in the second line on the
screen.
≤Misc. Commands:≥
⌠<F2>⌡ - Reset all counters.
⌠<F3>⌡ - Save all values to a text file (NET-ANA.PRN).
⌠<F4>⌡ - Toggle: Showing the output of the ethernet box.
⌠<F9>⌡ - Terminal.
⌠<Ctrl>-<F1>⌡ - Save screen contents into a file.
⌠<Alt>-<F3>⌡ - Switch between dirct and indirect video mode.
Stop the error analysis mode by ⌠<Esc>⌡.
