Bash scrip which ping several servers and execute command

[vinsbg]

Hello,

So far I have this script which pings 7 servers and execute an command if the server is alive. What I need is to put parameter which will change in the command according to server. For example:

ping SERVER 1 -> response with OK -> execute command /snmptrap -v 2c -c public server_1 param_1 ....
ping SERVER 2 -> response with OK -> execute command /snmptrap -v 2c -c public server_2 param_2 ....
ping SERVER 3 -> response with OK -> execute command /snmptrap -v 2c -c public server_3 param_3 ....

My problem is how to put in array those parameters ( 1; 2; 3; ) and in the command call them according to server which is alive. If server 1 is alive execute command with parameter 1 ... server 2 with parameter 2 and so on.

Here is the script that I ping the servers.

#!/bin/bash
servers=( "ip_serv_1" "ip_serv_2" "ip_serv_3" )

for i in "${servers[@]}"; do
    ping -c 1 $i > /dev/null && /snmptrap -v 2c -c public ...
done

EDIT:

Can I do something like this?

#!/bin/bash
servers=( "ip_serv_1" "ip_serv_2" "ip_serv_3" )
cmd=("1" "2" "3" "4")

for i in "${servers[@]}"; do
    ping -c 1 $i > /dev/null && /snmptrap -v 2c -c public ... $cmd...
done

But I guess if some host is down will mess the commands like this? SOmehow each $param must be assigned to corresponded host..

Thank you for replay!
I don't understand why I need this. I don't want to execute command from script on remote host. I will execute it on local.

Edit: I'm not shell-bash-script-guru and just starting to learn. That is why I dont understand some things.
