Ethernet-VBN architecture requirements
As shown in Figure 1-4 on page 1-10, Ethernet-VBN switches are set up in a
physical "tree" architecture. The YWS ETH 1 interface is provisioned as the
"Network Services System" at the "top" of the tree. The Network Services
System is provisioned as a single-port switch and serves as the VBN gateway
to the host LAN/WAN.
In addition, the following general requirements apply to all Ethernet-VBN
systems:
• Visitor computers must have a 10/100Base-T network interface card (NIC)
installed and appropriate cabling and adapters. See “Visitor computer
requirements” on page 1-5 for complete visitor computer requirements.
• A YesWare Ethernet-VBN system can support most enterprise-class
desktop switches comparable to the BayStack 303 or the Cisco 2900XL.
Ethernet-VBN switches can contain up to 24 ports (provisioned as ports
#1-24) and up to two high-speed/auxiliary ports (provisioned as
ports #25-26).
• All Ethernet-VBN switches must have assigned IP addresses. These IP
addresses must be identically assigned in both the switch console interface
and the YesWare Port Manager module.
• Ethernet-VBN switches that are "down" the switch architecture are
provisioned by configuring "downlink" ports in YesWare’s Port
Configuration dialog.
• Ethernet-VBN switches that are "up" the switch architecture are
provisioned as "Parent" switches.
• Each port connecting "down" to a switch must be configured with the
"downlink IP address" of the downlink switch.
• Each switch connecting "uplink" to a parent switch (all switches except the
YWS ETH 1) must be configured with the IP address of the parent switch.
Ethernet-VBN example
Using Figure 1-4 on page 1-10 as an example, note the following:
• "Ethernet Switch #1" is the parent switch of both "Ethernet Switch #2" and
"Ethernet Switch #3."
•The YWS ETH 1 interface is the parent of Ethernet Switch #1.
• For port #25 of Switch #1, the IP address of Ethernet Switch #2 must be
entered in the "Downlink IP Address" field of the Port Configuration
dialog.
• For port #26 of Switch #1, the IP address of Ethernet Switch #3 must be
entered in the "Downlink IP Address" field of the Port Configuration
dialog.
• For port #1 of the Network Services System (YWS ETH 1), the IP address
of Ethernet Switch #1 must be entered in the "Downlink IP Address" field
of the Port Configuration dialog.
Chapter 7, “Provisioning the Ethernet-VBN switches and ports” contains
complete instructions for using the Ethernet switch provisioning interface and
a more detailed architecture example.
