Hier,
Searching through the archives of this group and various docs I've
always come across this ACL for matching VoIP traffic:
access-list 101 permit udp any any range 16384 32767
My question is why don't people use this instead:
access-list 101 permit udp any any range 16384 32767 precedence
critical
?
IP Precedence 5 is 'critical' and my understanding is that VoIP
appliances like IP Phones transmit IP with that precedence. Is this a
fair question to ask a proctor or should we know this before walking
into the exam?
TIA,
-- Umair
