deny (IPv6 access-list configuration)
This is a list of ICMP message names:
Examples This example configures the IPv6 access list named CISCO and applies the access list to outbound traffic
on a Layer 3 interface. The first deny entry in the list prevents all packets that have a destination TCP
port number greater than 5000 from leaving the interface. The second deny entry in the list prevents all
packets that have a source UDP port number less than 5000 from leaving the interface. The second deny
also logs all matches to the console. The first permit entry in the list permits all ICMP packets to leave
the interface. The second permit entry in the list permits all other traffic to leave the interface. The
second permit entry is necessary because an implicit deny-all condition is at the end of each IPv6 access
list.
