An example of a default ACL on a campus access layer switch is shown below:

Extended IP access list ACL-DEFAULT
10 permit udp any eq bootpc any eq bootps log (2604 matches)
20 permit udp any host 10.230.1.45 eq domain
30 permit icmp any any
40 permit udp any any eq tftp
50 deny ip any any log (40 matches)

As seen from the output above, ACL-DEFAULT allows DHCP, DNS, ICMP, and TFTP traffic and denies everything else.
