With this command, you configure an IP access control list for the UDP protocol.
You have the following options:
● All incoming and/or outgoing UDP datagrams are not forwarded.
● Incoming and/or outgoing UDP datagrams of a specific host are not forwarded.
● Incoming and/or outgoing UDP datagrams of hosts of a specific subnet are not forwarded.
● Incoming and/or outgoing UDP datagrams are not forwarded to specific ports.
Note
Processing order of the lists
The access control lists are processed on the interface in the order in which they were
created.
The index number of the access control list is not used for this.
You are in the ACL standard configuration mode.
The command prompt is as follows:
cli(config-std-nacl)#
Call up the command with the following parameters:
deny udp {any | host <src-ip-address> | <src-ip-address> <src-mask>} [{ gt <src-port-
number(1-65535)> | lt <src-port-number(1-65535)> | eq <src-port-number(1-65535)> |
range <src-port-number (1-65535)> <src-port-number (1-65535)>}] [{any | host <dest-
ip-address> | <dest-ip-address> dest-mask>}] [{ gt <dest-port-number(1-65535)> | lt
<dest-port-number(1-65535)> | eq <dest-port-number(1-65535)> | range <dest-port-
