Description
A 13-bit bitmask showing which Type/Length/Value (TLV) fields were set
on the classifier. The following shows the meaning of each bit, with the
least significant bit on the far right. The bit is set to 1 if the corresponding
TLV was set for the classifier:
0x0001—IP Type of Service Range and Mask
•
0x0002—IP Protocol
•
0x0004—IP Source Address
•
0x0008—IP Source Mask
•
0x0010—IP Destination Address
•
•
0x0020—IP Destination Mask
•
0x0040—TCP/UDP Source Port Start and TCP/UDP Source Port End
0x0080—TCP/UDP Destination Port Start and TCP/UDP Destination
•
Port End
0x0100—Destination MAC Address
•
0x0200—Source MAC Address
•
0x0400—Ethertype/DSAP/MacType
•
0x0800—IEEE 802.1P User_Priority
•
0x1000—IEEE 802.1Q VLAN_ID
•
For example, a value of D6 translates to the bit-mask "1101 0110", which
indicates that the following fields were set for the classifier: IP Protocol,
IP Source Address, IP Destination Address, and the TCP/UDP Source and
Destination Port values.
Number of packets matching the classifier.
Address for the classifier in the internal SID table (SIDT).
Describes each packet classifier in detail.
ID used to uniquely identify the classifier in each service flow.
ID that uniquely identifies the service flow.
The matching IP source address.
The matching IP destination address.
The low-end and high-end matching destination TCP/UDP port values.
The matching IP protocol type, as given in
matches any IP protocol, and a value of 257 matches TCP and UDP traffic.
Indicates whether Payload Header Suppression (PHS) is active or inactive.
Indicates that PHS is being used on the downstream.
