Data Flow in VAS over 10G Topology
• VAS Data Flow: To the VAS Server, page 12-35
• VAS Data Flow: From the VAS Server, page 12-36
Data flow in the VAS solution over 10G topology depends on the appropriate use of VLAN tags to route
the packets through the system, from the 7600/6500 to the SCE platform, to the appropriate VAS server,
back to the SCE platform and then back to the network through the 7600/6500.
Figure 12-7 illustrates the flow of VAS data in the VAS solution over 10G topology. Note that the path
between the SCE platform and the VAS servers has the same VLAN tag for all SCE platforms in the
same EtherChannel.
