Script running for one iteration and failing the second one
Hi,
I am using Tclexpect to automation testing on switches and using regexp and the buffer outputs the program is running well for one iteration and failing the second one... can anyone please guide me what is the mistake i am making?

Thanks
Here is the small version of the program,
Code:
 while {1} {
                expect "#"
                send "clear counters\r"
                expect -re ".*#"
                expect "#"
                send "show interface port $port1,$port2 interface-rate\r"
                sleep 30
                expect "#"
                set  buff $expect_out(buffer)
                puts "Buff: $buff"
                regexp {(UcastPkts:[\t ]+([0-9]+)[\t ]+([0-9]+))} $buff match
                puts "$match"
                send "\r"
                 expect "#"
                send "sh spanning-tree stp $stp_vlan information\r"
                sleep 30
                expect "#"      
                send "clear counters\r"
                expect "#"
                send "sh interface port $port1,$port2 interface-rate\r"
                sleep 30
                expect "#"
                set buff $expect_out(buffer)
                puts "Buff=$buff"
                regexp {(UcastPkts:[\t ]+([0-9]+)[\t ]+([0-9]+))} $buff match
                puts "$match"
                send "\r"
                expect "#"
                send "sh mp cpu\r"
                sleep 10
                expect "#"
                send "sh mp memory\r"
                sleep 10
                }

Just saying the word failing is vary vague.

Can you be specific on the reason?

Example, if you are receiving an error message and what it is, what is the difference between the first and the second output, etc.

Okay here is the problem. I am using regexp at the beginning and the end of the loop because I want to compare the output of a certain command which shows the rate of packets coming in on a particular port on a switch.

I faced certain problems with clearing the buffer for the regexp match which I had to do. But I figured it out and the program seemed to run fine but its only working properly for one iteration and as soon as it enters the loop second time it gives me the TIMEOUT message. I havent posted the entire script over here. Please let me know if you need to see the entire script I can mail it to you.

Thanks a lot for replying.

Regards,

Rohan
