Syntax Description
interface-id
The input physical interface, the port on which the packet comes in to the
switch (including type, stack member, module, and port number).
switch (including type, stack member, module, and port number).
vlan vlan-id
(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.
the input interface is not a routed port, the default is 1.
src-mac
48-bit source MAC address.
dst-mac
48-bit destination MAC address.
l3protocol-id
(Optional) The Layer 3 protocol used in the packet. The number is a
value 0 to 65535.
value 0 to 65535.
ipv6
(Optional) IPv6 frame. This keyword is available only if the switch or
switch stack is running the dual-ipv4-and-ipv6 SDM template.
switch stack is running the dual-ipv4-and-ipv6 SDM template.
sap
(Optional) Service access point (SAP) encapsulation type.
snap
(Optional) Subnetwork Access Protocol (SNAP) encapsulation type.
cos cos
(Optional) Class of service (CoS) value of the frame. The range is 0 to 7.
ip src-ip dst-ip
(Optional, but required for IP packets) Source and destination IP
addresses in dotted decimal notation.
addresses in dotted decimal notation.
frag field
(Optional) The IP fragment field for a fragmented IP packet. The range
is 0 to 65535.

dscp dscp
(Optional) Differentiated Services Code Point (DSCP) field in the IP
header. The range is 0 to 63.
header. The range is 0 to 63.
l4protocol-id
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,
User Datagram Protocol (UDP), Internet Control Message Protocol
(ICMP), or Internet Group Management Protocol (IGMP), you should
use the appropriate keyword instead of a numeric value.

for the SCTP source and destination ports are 0 to 65535.
