grep and regex question

basically i have a csv i parse through. a user will supply me with a san switch he/she wants more info about... say the name is "pnj-sansw124"

now i can grep out every connection to that switch w/o issue because this sans switch pnj-sansw124 has multiple slots 1-10. and it looks like this in the csv "pnj-sansw124-1/23" where 1/23 is slot/port. so...

switch=pnj-sansw124
slot=1

Code:

grep -w $switch"-"$slot $file1 | awk -F, '{ print $2,$7 }' | while read cl1 cl2
do
    .
    .
    .
done

this works just fine

however i run into a problem where there is a san switch with no slots. so i would like to grep with a regex that would allow me to look for the "pnj-sansw124" but look for the "-[0-9]/" extension as well. so if its there, then continue to ask for slot. if not, go to a different section of code for this guy. a no slot san switch would look like "pnj-sansw110-58" where 58 is obviousy just the port.

i tried something like "pnj-sansw124-`([0-9]\{1\}|[0-9]\{2\})`//" but that didn't work out right.

thoughts?
