Vas Traffic Forwarding Topologies - Cisco SCE 8000 10GBE Software Configuration Manual

VAS Traffic Forwarding Topologies

VAS Traffic Forwarding Topologies
The following sections describe the following VAS traffic forwarding topologies:
•
•
A topology in which a VAS server is directly connected to the Cisco SCE platform is not supported. If
Note
you want a topology of a single Cisco SCE platform connected to a single VAS server, use a switch
between the Cisco SCE platform and the VAS server.
Single Cisco SCE Platform, Multiple VAS Servers
In this topology, a single Cisco SCE platform forwards VAS traffic to one or more VAS servers through
two Ethernet switches
The two Ethernet switches are necessary to avoid a situation in which a single MAC address has two
ports or a single VLAN tag has two destinations. Each Ethernet switch should be configured to trunk
mode with MAC learning disabled.
