Ethernet-VBN configuration requirements
When installing and configuring the Ethernet-VBN system, the following
system design and architecture requirements must be observed:
1The YWS ETH 1 interface must be configured as a "Network Services
System" switch (see Chapter 5).
2 The Ethernet-VBN system must be installed in a physical (as opposed to
virtual) tree configuration, with the YWS ETH 1 interface configured at
the “top” of the system tree.
3The YWS ETH 0 interface must be configured and connected to the LAN
with access to a WAN router. See Figure 7-1.
4 Each Ethernet-VBN switch can support multiple downlink switches, but
only one Parent or uplink switch. See Figure 7-1 and “Ethernet-VBN
configuration example notes” on page 7-4 for more information.
5 Ports connected to other switches or the YWS must be provisioned as
“network” ports, and must be assigned a Downlink IP Address. See
“Ethernet-VBN configuration example notes” on page 7-4 for more
information.
6 The Ethernet-VBN system does not support virtual LAN (vLAN) or virtual
spanning-tree functionality, and the Ethernet-VBN system cannot contain
any physical loops.
The following sections explain the requirements for the example Ethernet-
VBN configuration shown in Figure 7-1.
