Creating Match Lists and Rules
The VDSL2 card performs the following two actions:
Classification
– the service match lists are for matching and classifying traffic into
services.
Marking
– the service tag actions are for marking the traffic with the appropriate VLAN
and Priority required by the service.
This topic describes how to create a match list and then add an ordered collection of
matching rules to associate with a service tag action. The match list defines how the VDSL2
card classifies subscriber traffic to determine the service in which it belongs. A match list can
contain both “tagged” and “untagged” match rules, up to 12 tagged rules and up to 16
untagged rules.
Untagged match rules
can match on the following:
A portion of the source MAC address as indicated by the Source MAC and Source
MAC Mask attributes of a video Set-Top box
The Ethernet type to distinguish video and High-Speed Internet (HSI) untagged
traffic
All untagged traffic by using the system default match list "all-untagged".
PVC VPI and VCI port numbers.
The E7-2 VDSL2 line cards, E5-48C, E5-48, and E3-48C products support up to
six Services per DSL port that may be configured to support Voice, Data, Video,
TR-69 Management, Transparent LAN Services, or other VLAN assignments.
Support for multiple services is used when migrating from an ATM based
DSLAM to the E-Series solutions. If an E-series DSL product is placed in an
existing network that uses multiple PVC assignments, individual PVCs may be
mapped to specific VLANs that are applied to the port. For example, PVC
assignments (e.g. 0/33, 8/33, 0/35) may be mapped to individual data services
(“Data 1”, “Data 2”, “Data 3”) that are applied to the port. The E7-2, E5-48C,
E5-48, and E3-48C support one VC assignment per service.
TR-69 management channel (if present) is handled in-band over data VC.
