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.
Match
Number of packets matching the classifier.
SIDT
Address for the classifier in the internal SID table (SIDT).
Packet Classifier Details
Describes each packet classifier in detail.
Classifier ID
ID used to uniquely identify the classifier in each service flow.
SFID
ID that uniquely identifies the service flow.
IP source
The matching IP source address.
IP dest
The matching IP destination address.
UDP/TCP source range The low-end and high-end matching source TCP/UDP port values.
UDP/TCP dest range
The low-end and high-end matching destination TCP/UDP port values.
IP Protocol
The matching IP protocol type, as given in
RFC 1700
. A value of 256
matches any IP protocol, and a value of 257 matches TCP and UDP traffic.
PHS
Indicates whether Payload Header Suppression (PHS) is active or inactive.
Downstream Payload
Header Suppression
Indicates that PHS is being used on the downstream.
