i'm a bit confused about the "proper" way to configure a dynamic
acl.........i've ready the "cisco" way and seen the "IE" way but am confused
about which way to go.........

let's say that i want to allow one telnet host into R1......i've seen 2 ways
to do it

R1 (iIE WAY)
user r1 password cisco

line vty 0 4
login local
autocommand access enable host timeout 5

access-list extended auto
  dynamic telent permit tcp host 1.2.3.4 host 150.1.1.1 eq telnet
  deny tcp any any eq telnet
  permit ip any any

r1 (CISCO WAY)
user r1 password cisco

line vty 0 4
login local
autocommand access enable host timeout 5

acccess-list extended auto
pemrit tcp host 1.2.3.4 host 150.1.1.1 eq telnet
dynamic telnet timeout 120 pemit ip any any

what is the functional difference between the two?
