#Fonution : This shell is used to check the switch's port

#*****************expression********************
# The way to realize the function, we must create
# the vlan  according to the vlan switch. we create vlan's ID
# must equal to the switch's vlan ID.
# The detials as follows:
# For example:
# First of all, if we want to test the Switch's port 1 and the vlan switch has created vlans which id is between 2~48.
# we must create a vlan which id is 2 in localhost, and ping the destination ip, if ping'status OK, then the port1 is OK,
# or it bad. when it finished, we must remove the vlan we created, then create a new vlan which vlanID increase 1, and repeat
# the loop until the ports were tested over.

#****************var declare*********************
# SW_PORT_CONUT: the Switch's ports count
# TestRestult_File : the var mark the restult will be write to the file

TestResult_File="TestResult.txt"
echo "Please input the Switch Port's count :"
read SW_PORT_COUNT

#First, we write the log to the log file 
echo "TestResult_File is ${TestResult_File}"  
echo "we test Switch's ports'count is :${SW_PORT_COUNT}" > ${TestResult_File} 
echo "if some ports are OK, we can consider the port 1 is OK"

#****************************Create the vlan********************************
#because of the vlanID must start with 2
for((i=2;i<=${SW_PORT_COUNT};i++));do
#start the loop
#create the vlan 
vconfig add eth0 $i
#set the Ip addr for every vlan device
ifconfig eth0.$i 192.168.$i.34
ifconfig eth0.$i up
done

#*****************************Testing**************************************
echo "Testing......................."
#current test resutl
#we ping the destination IP, and get the result from return string
for((i=2;i<=${SW_PORT_COUNT};i++));do
#ping -c 3 -w 1 192.168.$i.35
temp_result=`ping -c 3 -w 1 192.168.$i.35|grep '% packet loss'|cut -d, -f3`
#echo "the temp_result is : ${temp_result}"
#we judge the result equal to the "0% packet loss"
#if the condition is true ,the port is OK
#or it is bad 
if [ "$temp_result" = " 0% packet loss" ] ;then 
   echo "we test port $i is OK" >> ${TestResult_File} 
else
   echo "we test port $i is Bad" >> ${TestResult_File}
