How to use a (Windows) CMD batchfile to run commands on Cisco MDS
I need to run some sort of script from a (Windows) host which runs 2 comamnds on the CLI of a Cisco MDS switch. Also: the output should be logged somewhere, preferrably to a log on that host.
Does anyone know how to do this? I want to fully automate it, so copy paste after starting an ssh session by using putty is not an option.
The commands I'm trying to run are:
show logging onboard | i "Module|FRAMES_DISCARD"
show interface counters | i "fc|B2B"

plink -ssh ip –l admin -pw password "show logging onboard | egrep Module|FRAMES_DISCARD"

You can actually generate and install an ssh key onto the cisco switch to eliminate the need for a password. Just create an public key file (NetBeans Help for netbeans.org Site Tools: Wiki: Winsshwithputty) and then make a user on the cisco switch and install the ssh key.
cont t
username dynamox password 0 role
username storagesvc sshkey
exit
Then you can ssh dynamox@switch and get in without a password. Great for scripts and automated process.

Your command to look at the b2b credits shows all interfaces, regardless of if they have active connections. Try the one below. It parses show flogi database to get a list of connections which have attached devices and show counters just for the active interfaces. Also it gets rid of the pesky more prompt.
show flogi database |inc fc |sed 's/ .*//' |sed -r -n 's/(.*)/show interface & counters | i "fc|B2B"/p' |vsh |no-mode

when you connect using plink you never get prompted for "more", it's the same as if you were to use | no-more

You may also want to take a look at TortoisePlink which is a modified version of plink that doesn't open up a console window. It's part of the TortoiseSVN project.

Good point.
You know me, I do a lot of automation.. I use a Perl module which creates an "interactive" ssh session, that way I can run commands and act on the output before doing the 2nd and 3rd step...
Best example is my script to active zone sets.. I check the number of active zones first, and make sure it matches...
But for these single command sessions, no need for " | no-mode"
