D
What type of connection will be made to the LAN?
For unshielded, twisted pair LANs, you can use the UTP port (8pin
modular jack). The NetRunner is then connected to a port on a
twisted pair hub. For other LANs, you must use the AUI port along
with an appropriate transceiver and transceiver cable.
The connections are described in the Integration Router manual. The
connections for the NetRunner 75E are described in the 3Slot Chassis
Installation and Cabling Manual.
D
Will you be using a frame relay link?
The following information is
needed from the carrier provider:
- DLCI numbers and parameters
- Network address
- Local management protocol (Annex D, LMI Rev. 1, or none)
Local management parameters (for the protocol)
- Type of interface required
(More information is provided on Frame Relay Links in Section 3).
Clusters
The NetRunner allows a network to be partitioned into groups called clusters.
A cluster is formed when two or more NetRunners are grouped together in
the network and given the same cluster name. A single cluster may contain
up to 12 interconnected NetRunners on a WAN. Configuring multiple
clusters allows you to create a WAN exceeding 12 nodes, up to a maximum of
254 NetRunner units per WAN.
All NetRunners are shipped with the same cluster name <none>. The cluster
name is userconfigured.
Clustering, as mentioned here, allows you to efficiently expand your network.
A cluster segments the network to improve performance and maximize
bandwidth for LAN traffic. This is especially true in larger networks
consisting of more than 12 NetRunners. It also secures portions of a network
by allowing communication only between NetRunners with the same cluster
name.
Clusters can only be interconnected over a LAN.
