IPv6 Support
IPv6 Support
The Cisco SCE 8000 devices support processing of IPv6 traffic. The features that are available for IPv4,
such as traffic processing, application classification and control, and management APIs, are available for
IPv6 too.
The Cisco SCOS enhances the IPv6 capabilities of Cisco SCE 8000 devices by providing support to both
IPv4 and IPv6 traffic simultaneously on all traffic processors.
Supported IPv6 features:
•
Subscriber awareness.
•
Virtual Gi
•
Subscriber based classification for IPv6 traffic.
•
Subscriber based bandwidth control.
•
Content filtering for IPv6 traffic flows.
•
Dual stack support on all traffic processors.
•
Reporting and monitoring of IPv6 traffic.
•
Support for IPv6 Fragmentation and Zones.
•
IPv6 bundling support in DS-lite.
•
Introduce IPv6 subscribers through Gx.
•
Raw Data Records, except Attack RDRs and Malicious Traffic RDRs, are enhanced for IPv6.
Redirection and blocking of traffic passing through 6to4, 6rd, and DS-Lite tunnels.
Cisco SCE devices work on three different system modes, namely, IPv4 only mode, IPv6 only mode, and
dual stack mode. The default mode is dual stack mode. To configure the system mode, see the
“Configuring the System Mode” section on page 3-17
The following limitations are applicable to the IPv6 features on Cisco SCE Release 4.0.x:
•
IPv6 addresses for connectivity to the management interfaces are not supported.
•
Tunneling—The L2TP, GRE, GTP, MPLS, MPLS-VPN tunnels are not supported.
•
Flow filter limitations:
–
For TCP flags, the PSH and URG fields are not considered, but SYN, ACK, RST, and FIN are
considered.
–
Range options are not provided for subscriber side IP and network side IP address; instead,
prefix length is used.
–
Inverse support is not provided for any of the fields.
•
Value-Added Services (VAS) are not supported.
•
Service classification and global bandwidth control are applicable for both IPv4 and IPv6. For
example, there is only one browsing service for both IPv6 and IPv4 browsing traffic. Allocating the
global bandwidth controller to a certain service limits the IPv6 and IPv4 traffic within that service.
•
The Services over IPv6 are classified under the same service IDs as the corresponding services over
IPv4.
•
Flow capture is not supported for IPv6.
