Hello Thomas,

Depending on what version of code you are running you can utilize python to achieve this. A script might already be written to achieve something similiar on the website below:

You can then tftp the py file to the switch and utilize the command "run script

So, the best way to xfer files is probably TFTP. Here is an example for a config file but the principle is the same for .xsf and .py files.

Once you have the .xsf or .py file on your switch, you would issue the command "load script {scriptname}" where the script file name is given without the suffix.

That said, you could also simply vi a file and type i for insert and then copy and paste the script contents into your terminal session. Then wq! to write to the file and quit the vi editor.

Also here is some code that when run in a script does an ELRP one-shot on every VLAN, every port and reports loops. You could probably modify it to do what you want.

#usage: load script elrp_oneshot
# USE THIS SCRIPT AT YOUR OWN RISK
#
disable cli prompting
disable clipaging
enable elrp-client
set var sv "#ELRP POLL STARTED#"
show var sv
set var cli.out 0
show vlan
set var sv $TCL(split ${cli.out} "\n")
set var e $TCL(lsearch $sv *(B)*)
set var i 5
set var e ($e - 1)
while ($i < $e) do
set var cli.out 0
set var v $TCL(lindex $sv $i)
set var vn $TCL(lindex $v 0)
set var z $TCL(regexp {Mgmt} $vn)
if ($z == 0) then
conf elrp-client one-shot $vn port all print
set var p $TCL(split ${cli.out} "\n")
set var p1 $TCL(lsearch $p *NO*)
if ($p1 == -1) then
set var p1 $TCL(lindex $p 2)
set var p2 $TCL(lindex $p1 9)
set var p1 $TCL(lrange $p1 0 6)
set var p1 $TCL(concat $p1 $p2)
set var p2 $TCL(lindex $p 3)
set var p2 $TCL(lrange $p2 5 7)
set var p $TCL(concat $p1 $p2)
show var p
else
set var p1 $TCL(lindex $p 2)
set var p2 $TCL(lindex $p1 10)
set var p1 $TCL(lrange $p1 0 7)
set var p1 $TCL(concat $p1 $p2)
show var p1
endif
endif
set var i ($i + 1)
endwhile
disable elrp-client
set var sv "#ELRP POLL COMPLETED#"
show var sv
enable clipaging
enable cli prompting

Good Morning,

thank you for your help in scripting under xos software
How i download a file to my swiches is not the problem, wie do it often with Netsight or

I want to give a feedback.
This script works exelent with our xos switche.

Good to hear. Thanks.

dr_watson — Thu, 23 Feb 2017 15:31:00 GMT

Yes, it works good.
But who can me explain what this Scripr do?
I know it is very difficulty for me to understand this.
I want to write a script which configure me the elrp protocoll on the switch. witch multiple vlans.
iI our networks we have ovver 1100 Extreme router or switche and i must
configue elrp to remove a loop in my network.

RE: scripting on xos switchen

Matthew_Helm1 — Thu, 23 Feb 2017 15:31:00 GMT

The script I posted is a "one-shot" elrp script that runs ELRP once on every VLAN every port to detect a loop.

It could be modified (and simplified) to instead enable ELRP on every VLAN every port permanently.

However, I would advise you to check with GTAC on the scale limits for ELRP based on switched configuration as having a large number of VLANs with a large number of ports in use with ELRP could overrun the CPU.

You can do this even with "Execute Command-Script" on Netsight. When you use XOS >21.x you can use vlan-id in some commands and not only vlan-names. I'm not sure, if this is included in elrp commands and XOS 16.x

nope, it doesn't include elrp. But the vlan name is easier to automate anyway, as it's VLAN_<4 digit vid> (for example: VLAN_0010 for vid 10).

if running 21.x+ I would imagine an App connecting to the switches, finding the vlans in use (with some criteria) and then apply the adequate config. Working with Python, json objects and jsonrpc could make it "easy".
