the network administrator, or a packet assigned rate limiting restrictions for
forwarding. The options are as follows:
• Permit, by which forwards packets which meet the ACL criteria.
• Deny, which drops packets which meet the ACL criteria.
• Shutdown, where drops packet that meets the ACL criteria, and disables the
port to which the packet was addressed. Ports are reactivated from the Port
Management screen.
• Protocol
By which creates an ACE (Access Control Event) based on a specific protocol
• Select from List
Where selects from a protocols list on which ACE can be based. The possible field
values are:
• Any, matches the protocol to any protocol.
• EIGRP, which indicates that the Enhanced Interior Gateway Routing Protocol
(EIGRP) is used to classify network flows.
• ICMP, which indicates that the Internet Control Message Protocol (ICMP) is
used to classify network flows.
• IGMP, which indicates that the Internet Group Management Protocol (IGMP) is
used to classify network flows.
• TCP, which indicates that the Transmission Control Protocol is used to classify
network flows.
• OSPF, by which matches the packet to the Open Shortest Path First (OSPF)
protocol.
• UDP, which indicates that the User Datagram Protocol is used to classify
network flows.
• Protocol ID to Match, adds user-defined protocols to which packets are
matched to the ACE. Each protocol has a specific protocol number which is
unique. The possible field range is 0-255.
• TCP Flags
This filters packets by TCP flag. Filtered packets are either forwarded or dropped.
Filtering packets by TCP flags increases packet control, and network security. The
values that can be assigned are:
• Set, which enables filtering packets by selected flags.
• Unset, disables filtering packets by selected flags.
• Don’t care, which indicates that selected packets do not influence the packet
filtering process.
The TCP Flags that can be selected are:
• Urg, indicates the packet is urgent.
• Ack, indicates the packet is acknowledged.
• Psh, indicates the packet is pushed.
• Rst, indicates the connection is dropped.
• Syn, indicates request to start a session.
