– UDP — User Datagram Protocol (UDP). Communication protocol that transmits packets but does not
guarantee their delivery.
• Source Port — Defines the TCP/UDP source port to which the ACE is matched. This field is active only if
800/6-TCP or 800/17-UDP are selected in the Select from List drop-down menu. The possible field range is 0
- 65535.
• Destination Port — Defines the TCP/UDP destination port. This field is active only if 800/6-TCP or 800/17-
UDP are selected in the Select from List drop-down menu. The possible field range is 0 - 65535.
• Source
– IPv6 Address — Matches the source port IPv6 address from which packets are addressed to the ACE.
– Prefix Length — Defines the number of bits that comprise the source IP address prefix, or the network
mask of the source IP address.
• Destination
– IPv6 Address — Matches the destination port IPv6 address to which packets are addressed to the ACE.
– Prefix Length — Defines the number of bits that comprise the destination IP address prefix, or the
network mask of the destination IP address.
• Flag Set — Sets the indicated TCP flag that can be triggered. The possible values are:
– Urg, Ack, Psh, Rst, Syn, and Fin.
The indicated value setting is represented by one of the following:
– 1 — Flag is set.
– 0 — Flag is disabled.
– x — Don’t care.
• ICMP Type — Filters packets by ICMP message type. The field values are 0-255.
• ICMP Code — Indicates and ICMP message code for filtering ICMP packets. ICMP packets that are filtered
by ICMP message type can also be filtered by the ICMP message code.
• DSCP — Matches the packets DSCP value.
• IP Prec. — Matches the packet IP Precedence value to the ACE. Either the DSCP value or the IP
Precedence value is used to match packets to ACLs. The possible field range is 0-7.
• Action — Indicates the action assigned to the packet matching the ACL. Packets are forwarded or dropped.
In addition, the port can be shut down, a trap can be sent to the network administrator, or packet is assigned
rate limiting restrictions for forwarding. The options are as follows:
– Permit — Forwards packets which meet the ACL criteria.
– Deny — Drops packets which meet the ACL criteria.
– Shutdown — Drops packet that meets the ACL criteria, and disables the port to which the packet was
addressed. Ports are reactivated from the Port Management Page.
• Delete — To remove an ACE, click the ACE’s checkbox and click the Delete button.
