Netsight ELRP script

Justsomebodi — Wed, 13 Apr 2016 21:18:00 GMT

Hi All

I need to change the settings of ELRP interval. I have found this script which i am sure can be used in Netsight.

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

enable clipaging

set var sv "#ELRP POLL COMPLETED#"

show var sv

But am unsure as to how much of it i need. All I need to do is conf elrp-client periodic vlan ($variable) ports all interval 20

The above sript does way more, so i assume i can delete parts of it. Does anyone know which ones?

Also would i need to add excluded ports to the script even though it has already been defined.

Changing the interval is a bit more complicated. If you were to try to change the interval of an existing elrp-client configuration, you would get a error message like: "ERROR: An active session already exists for "CLI:Default" !"

I can write a script that checks current configuration of elrp and changes the interval, if you'd like.

Thanks for that, so i assume then the ELRP would need to be removed and then re-enabled with the different interval on each Vlan. As i am no scripting guru i assume that's what the script does.

RE: Netsight ELRP script

Matthew_Helm1 — Thu, 14 Apr 2016 23:31:00 GMT

Yes. It takes the int variable in at the top and makes that the interval for all ELRP VLAN instances. It assumes you are not running any one-shot instances of ELRP on a VLAN. It only works on 16.1 forward because the ports are shown in the output without spaces in that release of EXOS fwd, else it could get really messed up.

Thanks for the explanation.

Hi

Tested the script and it failed with the below error

*** Error at line - 59 ***
invalid command name "config elrp-client periodic ports All interval 5 log disable-port ingress 300"

Line 59 is

set var recmd $TCL(concat "config elrp-client periodic" $v "ports" $p "interval" $int $lt)

I am so confused. Doesn't seem to like the ingress 300 bit.

if (!$t) then
set var recmd $TCL(concat $recmd "disable-port" $ie)
set var t $TCL(regexp {\d+} $d)
if ($t) then
set var d $TCL(concat "duration" $d)

So i did

set var recmd $TCL(concat "config elrp-client periodic" $v "ports" $p "interval" $int $lt)
if (!$t) then
set var recmd $TCL(concat $recmd "disable-port" $ie "duration")
set var t $TCL(regexp {\d+} $d)
if ($t) then
set var d $TCL(concat "duration" $d)
endif
set var recmd $TCL(concat $recmd $d)
endif

But still get the error.

invalid command name "config elrp-client periodic Extreme1 ports All interval 3 log disable-port ingress duration 300"

The command works in the cli.

What version of EXOS are you running?

RE: Netsight ELRP script

Justsomebodi — Wed, 27 Apr 2016 13:14:00 GMT

XOS 16.1.1.4

RE: Netsight ELRP script

Matthew_Helm1 — Wed, 27 Apr 2016 20:58:00 GMT

Can you also send me the output of a "show vlan" command. Perhaps there is something in the vlan name triggering. Also a "show elrp". (It might be good to issue the "disable clip" command before doing these commands). I'll try to configure my switch to match yours as closely as possible and test it.

RE: Netsight ELRP script

BTW, here is the ELRP configuration against which I tested the script:

I see you aren't using 16.1.1.4. Is it possibly a issue with 16.1.1.4?

RE: Netsight ELRP script

Matthew_Helm1 — Thu, 28 Apr 2016 01:26:00 GMT

Just tested on 16.1.1.4 and no errors either.

The script ends up removing all Vlan's. I am using this from Netsight as a admin script.

RE: Netsight ELRP script

Matthew_Helm1 — Fri, 29 Apr 2016 00:58:00 GMT

I assume you mean the script ended up removing ELRP from all VLANs. I've been testing it from the CLI. I'll test it from NS when I have a chance.

RE: Netsight ELRP script

Justsomebodi — Fri, 29 Apr 2016 01:39:00 GMT

Yes, sorry mean elrp from the vlan's. I am running the script from Oneview so is not actually Netsight (6.3.0.168)

RE: Netsight ELRP script

I modified it to work in as a OneView script:

Thanks, i will give it a test.
