Appendix C
The input physical port, the port on which the packet comes in to the
switch.
(Optional) Input VLAN ID. The range is 1 to 4094. If not specified, and
the input interface is not a routed port, the default is 1.
48-bit source MAC address.
48-bit destination MAC address.
(Optional) The Layer 3 protocol used in the packet. The number is a
value 0 to 65535.
(Optional) Service access point (SAP) encapsulation type.
(Optional) Subnetwork Access Protocol (SNAP) encapsulation type.
(Optional) Class of service (CoS) value of the frame. The range is 0 to 7.
(Optional, but required for IP packets) Source and destination IP
addresses in dotted decimal notation.
(Optional) Differentiated Services Code Point (DSCP) field in the IP
header. The range is 0 to 63.
(Optional) The IP fragment field for a fragmented IP packet. The range
is 0 to 65535.
The numeric value of the Layer 4 protocol field in the IP header. The
range is 0 to 255. For example, 47 is generic routing encapsulation
(GRE), and 89 is Open Shortest Path First (OSPF). If the protocol is TCP,
UDP, ICMP, or IGMP, you should use the appropriate keyword instead
of a numeric value.
Internet Control Message Protocol (ICMP) parameters. The icmp-type
and icmp-code ranges are 0 to 255.
Internet Group Management Protocol (IGMP) parameters. The
igmp-version range is 1 to 15; the igmp-type range is 0 to 15.
Transmission Control Protocol (TCP) parameters: TCP source port,
destination port, and the numeric value of the TCP flags byte in the
header. The src-port and dst-port ranges are 0 to 65535. The flag range
is from 0 to 1024.
User Datagram Protocol (UDP) parameters. The src-port and dst-port
ranges are 0 to 65535.
