Figure 31 Uplink Ports Designation
9.1.1 Configuration of VLANs in RSTP Scenarios
When RSTP is used, all service VLANs used within the daisy chained nodes
must be configured in all Ethernet access switches. If PEM is used, and the
services are defined as configured automatically, all services will be configured
correctly, provided that the connected Ethernet access switches are defined. If
the Ethernet access switches are configured by CLI or SNMP, a switching
domain for each VLAN must be configured in all Ethernet access switches,
with uplink port and transit link port as illustrated in Figure 32 on page 75. Note
that the EFN324 automatically reverses the uplink and change the port
designation after the spanning tree has disabled the link.
