3Com 3031 Command Reference Manual page 353

The above information will be displayed after entering the command series, in
which the contents in boldface are those related to X.25 and LAPB protocols. The
main parameters are described as follows:
Link-protocol is X.25 DCE Ietf: Current encapsulation protocol of this interface
is X.25 protocol that works in DCE mode, and the data packet encapsulation
format is IETF.
address is: X.121 address of this X.25 interface; this field will be empty if there
is no address.
state: Current status of this X.25 interface.
modulo: Data packets and traffic control packets sent by this X.25 interface are
numbered in modulo 8 mode.
input/output: Window sizes 7/7, packet sizes 256/256: Flow control
parameters of this X.25 interface, including receiving window size, sending
window size, maximum received packet size (in bytes), and maximum sent
packet size (in bytes).
Channels: Channel range division of this X.25 interface, sequentially as
incoming-only channel section, two-way channel section, outgoing-only
channel section; if both demarcating values of an section are 0, this section is
disabled.
Timers: Delay values of various timers of this X.25 interface, in unit of second.
New Configuration: New configuration of this X.25 interface taking effect after
next restart; if this configuration is wrong, the default value will be restored.
Restarts 0 ( Restart Collision 0): Statistics of this X.25 interface, including times
of restart (including restart collision).
Refused Incoming Call: Statistics information of this X.25 interface: times of
call refusals. times of call failures.
Failing Outgoing Call: Statistics information of this X.25 interface:
input/output: RESTART 1/1 ... REJ 0/0:Statistics information of this X.25
interface: quantities of received and sent packets, format: received
quantity/sent quantity.
Invalid Pr: Error statistics information of this X.25 interface: total of received
data packets and traffic control packets carrying erroneous acknowledgement
numbers.
Invalid Ps: Error statistics information of this X.25 interface: total of received
data packets carrying erroneous sequence numbers.
Unknown: Error statistics information of this X.25 interface: total of received
irresolvable packets.
Link-protocol is LAPB: Current encapsulation protocol of this interface is LAPB
protocol.
LAPB DCE: LAPB of this interface works in DCE mode.
module 8: Information frame and monitoring frame sent by this interface LAPB
are numbered in the modulo 8 view.
window-size 7: Window size of this interface LAPB is 7.
