This page is a reference fo all VTY commands that you can use interactively on the osmo-gbproxy VTY telnet interface on TCP port 4246

In addition, the same commands are used for the configuration file.

h2. configuration reference

h3. gbproxy level

h4. nsip sgsn remote ip A.B.C.D

Set the remote IP address for the connection to the SGSN.

h4. nsip sgsn remote port <0-65534>

Set the remote UDP port for the connection to the SGSN.

h4. nsip sgsn nsei <0-65534>

Set the NSEI for the connection to the SGSN.

h4. nsip sgsn nsvci <0-65534>

Set the NS-VCI for the connection to the SGSN.

h3. ns level

h4. timer (tns-block|tns-block-retries|tns-reset|tns-reset-retries|tns-test|tns-alive|tns-alive-retries) <0-65535>

Set the respective NS (GSM TS 08.16) timer to the corresponding value (in seconds):

* tns-block -- Timer between NS-BLOCK attempts without any NS-BLOCK-ACK response

* tns-block-retries -- How often to retransmit an unacknowledged NS-BLOCK

* tns-reset -- Timer between NS-RESET attempts without any NS-RESET-ACK response

* tns-reset-retries -- How many times should we retry to send NS-RESET

* tns-test -- How many seconds to wait for the response to a TEST procedure

* tns-alive -- How many seconds to wait for an answer to the ALIVE procedure

* tns-alive-retries -- How often should we retry the ALIVE precedure before declaring the link DEAD

h4. nse <0-65535> nsvci <0-65534>

Configure a persistent NS-VC with a given NSEI and NSVCI

h4. nse <0-65535> remote-ip A.B.C.D

Set the remote IP address for a persistent NS-VC

h4. nse <0-65535> remote-port <0-65535>

Set the remote UDP port for a persistent NS-VC

h4. nse <0-65535> remote-role (sgsn|bss)

Set whether the remote end of the specified persistent NS-VC is a BSS or SGSN.

h4. no nse <0-65535>

Remove the persistent configuration for the specified NSE

h2. runtime commands

h3. show ns [stats]

Show a list of all existing NS-VCs

<pre>

proxy.osmocom.org> show ns

NSEI  2342, NS-VC  2342, Remote: BSS ,  DEAD   BLOCKED,  192.161.252.121:23000

If the stats parameter is given, statistics will be included.

h3. show ns (nsei|nsvc) <0-65535> [stats]
