DESCRIPTION

The ntx_chinfo command gives network connection information for each channel on the specified channel range. The range may be specified in any of the following formats :

i. -<end_chan>

The start channel is assumed to be zero. the display ends at channel number end_chan.

ii. <start_chan>-

The end channel is assumed to be the last configured channel. The display begins at <start_chan> and ends at the last configured channel id on the ntx board.

iii. <start_chan>-<end_chan>

The entire range is specified. The display begins at <start_ chan> and ends at <end_chan>.

If no range is specified, the entire range as configured on the board is assumed. The display information shows the following parameters:

−Minor#
The minor device number of the port corresponding to the channel

−chan#
The channel number on the MVME339

−call_type
shows whether the channel is CALL_IN or CALL_OUT type

−service
The service assigned when a connection is established

−client_address

TCS_OPEN - The channel has been opened by the host

TCS_CLSD - The channel has been closed by the host ( may or may not yet have a network connection... See NET_CONN below )

TCS_CLOSI - The channel is closing .... waiting for the output data to drain

NET_RDERR - The network error on the input side of the connection

NET_WRERR - The network error on the output side of the connection

NET_CONN - The channel has a network connection although either or both sides of the connection may have been lost ( See NET_RDERR and NET_WRERR above )

NET_RECON - The channel connection has been maintained across a close and open command sequence from the host

NET_CALIN - A call-out channel is trying to establish network connection

OPTIONS

−draw device filename. This option overrides the default device name of /dev/xedt/mvme338_c0.

−udisplays usage and quits. Overrides all other options

−hdisplays header showing date, device name, its type and total number of channels configured on that device
