7-2 Provisioning the Ethernet-VBN switches and ports
Software Release 2.30 YesWare Applications User’s Guide 08-01016-01
Ethernet-VBN switch architecture and configuration requirements
The major steps required to provision switches in an Ethernet-VBN system
include the following:
1 Install the Ethernet switches on the visitor (ETH 1) network.
2 Install the YWS ETH 1 interface on the same LAN segment as the
Ethernet-VBN switches.
3 Provision the VBN gateway and Network Services System switch (see
Chapter 5)
4 Add the Ethernet-VBN switch IP addresses, switch configurations,
and port configurations to the YesWare database.
This chapter contains instructions for step 4 of the above list, using the
Ethernet switch and port configuration dialogs to provision an Ethernet-VBN
system. The following sections describe the architecture and configuration
requirements for Ethernet-VBN systems.
Ethernet-VBN architecture provisioning requirements
Ethernet-VBN switches are configured in an "inverted-tree" architecture, with
the YWS ETH 1 port serving as the top or "trunk" of the inverted tree, and the
Ethernet-VBN switches serving as the tree "branches." The inverted switch-
tree architecture is provisioned by setting "downlink" port connections
between switches, and provisioning "parent" switches that are used to form the
tree branches.
Ethernet-VBN downlink ports
Downlink ports are the ports on a switch that connect to ports on other switches
that are "down" the switch-tree architecture. Each port "downlink" to a switch
must be assigned the IP address of the downlink switch in the "Downlink IP
Address" field of the Port Configuration dialog.
Ethernet-VBN parent switches
Parent switches are the first switch "up" the switch-tree architecture from the
switch being configured. All Ethernet-VBN switches except the YWS ETH 1
must have one (and only one) parent switch. Each switch must have the IP
address of its parent switch assigned in the "Parent Switch IP Address" field
of the Switch Configuration dialog.
