Netsight ELRP script

[Justsomebodi]

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.

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.

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.
