Results of LIST command

The following example illustrates the results of the LIST command:

EZB2020R MCH XU038    state 1050
EZB2021R VC 010 LU VL038001 DTE 00000039        state 4050
EZB2021R VC 00F LU          DTE                 state 1010
               ...
EZB2021R VC 001 LU          DTE                 state 1010
EZB2022R IP AS TCPIPTES state 80

The LIST command is useful to get a snapshot of virtual circuit status. This example shows a normal status with one active VC (state 4050). VC state 1010 indicates ready but not in use. With the NPSI fast connect feature, the normal idle state is 1050. Other intermediate states can appear while an X.25 call or clear is in progress. The codes are listed in z/OS Communications Server: IP Messages Volume 1 (EZA).

The status of the path to TCP/IP is shown in the last line:

80 is normal
00 indicates that the TCPIP X25 NPSI device has not been started
