Hello Rahul,
The only issue I found on running a tcl script similar to [yours] below on a
locked down desktop is that if the output exceeds the buffer limit of the
terminal emulator the first xxx lines are lost. There are a few ways to
counter this such as
conf t
line vty 0 4
!or line con 0
length 25
end
but this is not ideal as it will suspend your script and requires you to
change your config.
To improve on this would require the ability to communicate via file
systems. eg
eg 1) to pause a script without changing the line length on the router
set answer [gets stdin]
eg 2) to dump output to a file
set f "flash:\test.txt"
set x [open $f a]
puts $x [rsh $i ping $j]
close $x
Does anyone know [or can they test] if the tcl on a multiservice router
(26xx, 36xx) will support stdin and/or file system access for dumping the
output to a file somewhere in the filesystem, so that the output can be read
back with more?
Following a more complete scripts
Script 1 - standard ping all from all routers and sh ip route script
tclsh
foreach i {
1.1.1.1
1.1.1.2
} {
puts "****************$i***********************"
rsh $i sh ip route
foreach j {
1.1.1.1
10.1.1.1
11.1.1.1
12.1.1.1
13.1.1.1
1.1.1.2
20.1.1.1
21.1.1.1
22.1.1.1
23.1.1.1
} {
rsh $i ping $j
}
}
tclquit
Script 2 - attempt [unverified] to use file systems
tclsh
set f "flash:\\test.txt"
set x [open $f a]
foreach i {
1.1.1.1
1.1.1.2
} {
puts $x "****************$i***********************"
puts $x [rsh $i sh ip route]
foreach j {
1.1.1.1
10.1.1.1
11.1.1.1
12.1.1.1
13.1.1.1
1.1.1.2
20.1.1.1
21.1.1.1
22.1.1.1
23.1.1.1
} {
puts $x [rsh $i ping $j]
}
set answer [gets stdin]
}
close $x
tclquit
more flash:\test.txt
!Note 1
!could use more nvram:\test.txt instead
!Note 2
!more will still require changing of the router's line length, but at least
[if the script works] the output can be reviewed when you are ready and not
have to watch the script run.
ie - if anyone has a [non production] multiservice router accessible, we all
would be greatful if script 2 could be tested!!

Dear Kasturi ,
Any help is always appreciated . any ways i am yet far away from 8hr
sessions.
wat i really wanted to ask for is small tricks n tips , well one of my ccie
freinds says
ccie is a fight against time ,the more u save ,the better coz u can review
ur
configs .
Th script he asked me to use is :
tclsh
foreach test {
10.1.1.1
10.2.2.2
10.3.3.3
10.4.4.4
} {ping $test} ps: works on 12.2t and above n mostly seen on 26xx (yet to
see
a 25xx with it)
This way for checking end to end connectivity i don't have to type in more
key
storkes .
just one script and test it on all the routers well saves 15 min , just type
all ips in
a note pad along with the script and boy u r not waiting for a ping to
finish
to resume another one .
well i just wanted to know if there are other similar short tricks that
could
make life easier .
i bet this script will sure help a lotta guys who din't know {if people like
that exist on this forum}.
well i use a long list of alias commands and practice to type them in just
abt
10 min .so that i can save time .
well i have made this post before but just if someone missed it here it is
again .
