ethernet-protocol: Protocol type domain in the Ethernet packet header, in the length of
2 bytes.
fragments Fragment tag bit in the IP packet header.
icmp-code: ICMP code domain, in the length of 1 byte.
icmp-type: ICMP type domain, in the length of 1 byte.
ip-precedence: IP priority domain in the IP packet header, in the length of 1 byte.
ip-protocol: Protocol type domain in the IP packet header, in the length of 1 byte.
sip: Source IP domain in the IP packet header, in the length of 4 bytes.
smac: Source MAC domain in the Ethernet packet header, in the length of 6 bytes.
sport: Source port domain, in the length of 2 bytes.
tcp-flag: Flag domain in the TCP packet header, in the length of 1 byte.
tos: TOS (type of service) domain in the IP packet header, in the length of 1 byte.
vlanid: VLAN ID in the Ethernet packet header, in the length of 2 bytes.
Description
Using the flow-template user-defined template-info command, you can define a flow
template. Using the undo flow-template user-defined command, you can delete a
flow template.
In defining a flow template, the total length of all elements should not be more than 16
bytes.
 Note:
The numbers listed in the table are not the actual length of these elements in IP packets,
but their length in flow template. DSCP field is one byte in flow template, but six bytes in
IP packets. You can judge the total length of template elements using these numbers.
The dscp, ip-precedence and tos fields jointly occupy one byte. One byte is occupied
no matter you define one, two or three of these fields.
The fragment field is 0 in length in flow template, so it can be ignored in calculating the
total length of template elements.
