Chapter 14 Value-Added Services (VAS) Traffic Forwarding
VAS Traffic Forwarding Topologies
In
, the top Cisco SCE platform forwards traffic to VAS Server 1 and Server 2, while the
bottom Cisco SCE platform forwards to VAS Server 2 and Server 3. A unique VLAN tag must designate
each Cisco SCE-platform-to-VAS-server path. This topology is illustrated with two Cisco SCE
platforms, but a maximum of 512 Cisco SCE platforms is supported (limited by the VLAN tag size).
The two Ethernet switches route the traffic to the VAS servers. The routing is VLAN based. The Ethernet
switch should be configured to trunk mode with learning disabled.
The data flow is the same as that for the single Cisco SCE platform to multiple VAS servers topology
(see
“Data Flow” section on page 14-15
).
Note
The multiple Cisco SCE platforms to multiple VAS servers topology does not support Cisco SCE
platform redundancy on the cascade ports.
