Configuring the PathBuilder S200 Series Switch for Bridging Operation
Configuring Source Route Bridging Operation
Introduction
You configure a node for Source Route Bridging during normal bridge configuration.
Refer to “Configuring the PathBuilder S200 Series Switch for Bridging Operation”
section on page 21 for more details.
This section provides some guidelines you should consider when configuring a node
for Source Route Bridge operation.
Configuring the
Node for SRB
Operation
The Node must be enabled for Bridge operation and some general parameters
established in the “Software Key” and “Node Record” sections of the configuration
menu.
• Make sure the CSK is entered for Source Route Bridging (SRB).
• The subaddress within the node for the bridge module should be specified.
This allows the bridge connections to other nodes to be targeted to the right
subaddress upon entering the node.
• A Codex Proprietary Protocol ID must be specified in the Node Record to
ensure that calls for other traffic types, if mistakenly connected to the bridge
subaddress, are rejected. Only similar remote bridges must identify
themselves with this ID.
For details on configuring the Node record, refer to the PathBuilder S200 Series
Basic Protocols.
Individual Bridge
Links
Once you complete node and port configuration, individual bridge links to other
nodes must be established, up to a maximum of 32 per node. Figure 20 shows LAN/
WAN Bridge Links used in a PathBuilder S200 series switch LAN network.
