6-12CHAPTER 6: CONFIGURING BASIC SETTINGS

The syntax variation for non-ISDN interfaces applies to local area network (LAN) and data terminal equipment (DTE) interfaces.

NETBuilder software menus and help strings do not display the syntax variation for

ISDN interfaces.

The variation in syntax is caused partially by the different path-numbering convention used for ISDN. For information, refer to Using NETBuilder Family Software. Special parameter values related to built-in ISDN interfaces can also cause a variation in syntax.

Some parameters in ISDN-specific software are connector-related and require that you specify a connector number (<connectorID>), for example, 2. Other parameters are channel-related and require that you specify both a connector and a channel number (<connectorID.channelID>), for example, 2.1. When you specify both a connector and a channel number, you must separate them with a decimal point.

If you do not specify a channel number in a command that requires both a connector and a channel number, the software assumes the first channel associated with the connector. For example, if you specify connector number 2 when the syntax requires that you to specify both a connector and a channel number, the software assumes you mean 2.1.

To specify all channels associated with a connector, specify the connector number, a decimal point, and an asterisk, for example, 2.*

Address Formats The following summary describes media addresses and network layer addresses the bridge/router uses and their formats. For detailed information on protocol-specific addressing, refer to Reference for NETBuilder Family Software.

Media Addresses

MAC	Contains 12 hexadecimal digits preceded by a percent sign (%).
	The NETBuilder II bridge/router has a media access control (MAC)
	address (physical) for each LAN interface (Ethernet, FDDI, or token
	ring), for each HSS interface, and for the CEC module.
	The MAC address and the network identifier constitute a network
	address, which is the only address used by Xerox Network Systems
	(XNS) and Internetwork Packet Exchange (IPX) routers. IP routers
	have both MAC addresses for their LAN interfaces and Internet
	addresses for their configured ports. Internet addresses are
	described in “Network Layer Addresses” on page 6-14.
	Each MAC address is assigned by 3Com. A MAC address can be
	displayed by entering:
	SHow -SYS ADDRess
	The following is an example of a MAC address:
	%080002001326
