Multiple-Switch Topology

A typical EVLAN configuration has multiple switches, interconnected with VLAN trunks. The example configuration in this section illustrates how to interconnect two SEFOS switches (SEFOS1 and SEFOS2), and extend the EVLAN across them. There are two restricted EVLANs on these switches under principal EVLAN 100.

This figure shows the IP addresses and port assignments for the multiple-switch configuration. In this example, port 1 is the external port on both switches (SEFOS1 and SEFOS2). On SEFOS1, ports 19 and 20 are solitary-restricted internal ports, and ports 2 and 15 are group-restricted internal ports. On SEFOS2, ports 11 and 12 are solitary-restricted internal ports. Port 2 is the only group-restricted internal port.
