■
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.

■
ICMP Type
— Specifies an ICMP message type for filtering ICMP
packets.
■
ICMP Code
—Specifies an 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.
■
IGMP Type
— IGMP packets can be filtered by IGMP message type.
■
Source
— Defines the TCP/UDP source port to which the ACL is
matched.
■
Destination
— Defines the TCP/UDP destination port.
■
DSCP
—Matches the packet DSCP value to the ACL. Either the DSCP
value or the IP Precedence value is used to match packets to ACLs. The
possible field range is 0-63.
■
IP - Prec.

ip-precedence value.
