DOCSIS 1.1 for Cisco uBR905 and Cisco uBR925 Cable Access Routers and Cisco CVA122 Cable Voice Adapters

Command Reference

Cisco IOS Release 12.2(15)CZ

valid 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 Detailed description of each packet classifier.

Classifier ID ID used to uniquely identify the classifier in each service flow.

SFID ID that uniquely identifies the service flow.

IP source Matching IP source address.

IP dest Matching IP destination address.

UDP/TCP source range Low-end and high-end matching source TCP/UDP port values.

UDP/TCP dest range Low-end and high-end matching destination TCP/UDP port values.

IP Protocol 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 Whether payload header suppression (PHS) is active or inactive.

Downstream Payload

Header Suppression

Whether PHS is being used on the downstream.
