Shell Programming and Scripting

I have a file abc.sh which looks like
qacc1 ----> down
v5c0
check interface v5c1

I want to read this file line by line and perform a certain action if a particular pattern is found in that line. My code so far looks like this:

FileName='abc.sh'
while read LINE
do
echo $LINE
case $LINE in
"v5c0") echo "v5c0 found" ;;
"qacc1") echo "qacc1 found" ;;
*) echo "not found" ;;
esac
done < $FileName

the output for this code is:
qacc1 ----> down
not found
v5c0
v5c0 found
v5c1
not found

this code says not found if the pattern is in a line. like qacc1 ----> down
I have tried a number of patterns matching configurations and could get none of them to work. I am new to shell scripting and I am still learing.
It would be great if someone could help me with this.

Code:

...
case $LINE in
*v5c0*) echo "v5c0 found" ;;
*qacc1*) echo "qacc1 found" ;
....

thanks it works
