Figure 47: IPv4 Based ACL Page

The IPv4 Based ACL Page contains the following fields:

• ACL Name — Displays the specific IP based ACLs.

• Remove ACL — Deletes the specified ACL. The possible field values are:

– Checked — Deletes the ACL when user clicks the Apply button.

– Unchecked — Maintains the ACL.

• ACE Priority — Indicates the rule priority, which determines which rule is matched to a packet on a first-

match basis.

• Protocol — Creates an ACE based on a specific protocol. The available protocols are:

– ICMP — Internet Control Message Protocol (ICMP). The ICMP allows the gateway or destination host to

communicate with the source host. For example, reporting a processing error.

– IGMP — Internet Group Management Protocol (IGMP). Allows hosts to notify their local switch or router

that they want to receive transmissions assigned to a specific Multicast group.

– IP — Internet Protocol (IP). Specifies the format of packets and their addressing method. IP defines

addresses to packets and forwards the packets to the correct port.

– TCP — Transmission Control Protocol (TCP). Enables two hosts to communicate and exchange data

streams. TCP guarantees packet delivery, and guarantees packets are transmitted and received in the

order they are sent.

– EGP — Exterior Gateway Protocol (EGP). Permits the exchange of routing information between two

neighboring gateway hosts in an autonomous systems network.

– IGP — Interior Gateway Protocol (IGP). Permits the exchange of routing information between gateways

in an autonomous network.

– UDP — User Datagram Protocol (UDP). Communication protocol that transmits packets but does not

guarantee their delivery.
