Chapter 3 Initially Configuring the ATM Switch Router Methods for Configuring the ATM Switch Router Methods for Configuring the ATM Switch Router The ATM switch router defaults to a working configuration suitable for most networks. However, you might need to customize the configuration for your network. Note If your Telnet station or SNMP network management workstation is on a different network from the switch, you must add a static routing table entry to the routing table.

Chapter 3 Initially Configuring the ATM Switch Router Configuring Network Clocking Configuring Network Clocking with NCDP The Network Clock Distribution Protocol (NCDP) provides a means by which a network can synchronize automatically to a primary reference source (PRS). To do so, NCDP constructs and maintains a spanning network clock distribution tree.
Chapter 3 Initially Configuring the ATM Switch Router Configuring Network Clocking Enabling NCDP To enable NCDP, use the following global configuration command for each node that you want to configure for NCDP: Command Purpose ncdp Enables NCDP. Configuring Network Clock Sources and Priorities You must specify the clocking sources, their priorities, and associated stratums used by NCDP in constructing the clock distribution tree.
Chapter 3 Initially Configuring the ATM Switch Router Configuring Network Clocking When you specify a maximum diameter, you constrain the diameter of the spanning tree by specifying the maximum number of hops between any two nodes that participate in the protocol. Each node must be configured with the same maximum network diameter value for NCDP to operate correctly.
