Hi - I have issues associated with this command:

function run(cli, device) {
    cli.macro("configure");
    cli.command("default terminal length");
    cli.command("terminal length 35");
    cli.macro("end");
    cli.macro("save");
}

Reproducing the problem has gone like this:

1. Connect to the switches (I can reproduce on the ERS48XX and ERS35XX series)
2. Configure terminal length 0
3. Now run the script above

The values for the length will not change. Even if I simply use terminal length 35 and leave the default terminal length statement out. Script runs as expected and reports success, but the value never changes on the switch and stays at terminal length 0.

Hello, Could you run the commands manually on a device and copy/paste the full outputs here? Apart from the Run command script, is the device properly discovered, and the configuration properly retrieved by Netshot?

[orgitnized]

Yep, other commands work perfectly and the device is properly discovered. I can reproduce this on every 35XX and 48XX series device I have. Here's the output from every switch that takes the command:

mdf-stk-1(config)#terminal length ?
  <0-132>  Set number of lines on a screen
mdf-stk-1(config)#terminal length 35 ?
  <cr>

mdf-stk-1(config)#terminal length 35

It's really strange...I can do terminal width commands and they change as expected. But terminal length commands simply do not work.

To capture the exchanges between the Netshot Avaya driver and the switch itself, you can follow this procedure:

On the server, edit the Netshot configuration file, e.g. /etc/netshot.conf, and add the following line: netshot.log.class.onl.netfishers.netshot.device.access.Cli = ALL

Then restart Netshot: #service netshot restart

Run the command script again and capture the output of /var/log/netshot/netshot.log.

Once done, rollback the change on the configuration file, as you don't want to run in full debugging mode the rest of the time.

Here we go!

This is the command that was sent via netshot

function run(cli, device) {
    cli.macro("configure");
    cli.command("default terminal width");
    cli.command("terminal width 132");
    cli.command("default terminal length");
    cli.command("terminal length 35");
    cli.macro("end");
    cli.macro("save");
}

Hello,

The Avaya driver in Netshot automatically sends terminal length 0 to the device each time it goes to exec enable mode. I suspect terminal length typed in exec mode (not in config mode) still changes the configuration... I don't have an Avaya device accessible right now, can you double-check? If this is the case, just move your cli.command("terminal length 35"); after cli.macro("end");.

[orgitnized]

I'm sorry for the delay in responding. Here's what I ran as a task:

function run(cli, device) {
    cli.macro("configure");
    cli.command("default terminal length");
    cli.command("default terminal width");
    cli.macro("end");
        cli.command("terminal length 35");
        cli.command("terminal width 132");
    cli.macro("save");
}

The task runs as a SUCCESS When I connect to the stack, the configuration is still wrong. Here's what it shows:

khs-idf1-stk-1#show terminal
Terminal speed: 9600
Terminal width: 132
Terminal length: 0 (pagination disabled)

[SCadilhac]

Netshot will disable the pager (terminal length 0) again after running the macro. You can try to move cli.command("terminal length 35"); after cli.macro("save");.

Got it - that does the trick, thanks!
