If multiple routes to the same destination are specified, they are listed in descending order of priority. The routes consist of a list of IP address pairs.
  • Page 79 configured as described in RFC 1001/1002. The value is specified as a single octet which identifies the client type. A value of 1 corresponds to a NetBIOS B-node; a value of 2 corresponds to a P-node; a value of 4 corresponds to an M-node; a value of 8 corresponds to an H-node. strin option netbios-scope The NetBIOS scope option specifies the NetBIOS over TCP/IP scope parameter for the client as...

    Chapter 9 DHCP Client Configuration This section describes basic configuration options for the DHCP Client; these are placed into an ASCII file which is read by the system at startup f) via ISFS (which in turn may be retrieved from (dhclient.con FLASH, if the file exists there).

    9.1.4 Reboot reboot time; When the client is restarted, it first tries to reacquire the last address it had. This is called the state. If it is still attached to the same network it was attached to when it last ran, this is the INIT-REBOOT quickest way to get started.

    9.3 Other declarations 9.3.1 Reject reject ip-addres The reject statement causes the DHCP client to reject offers from servers who use the specified address as a server identifier. This can be used to avoid being configured by rogue or misconfigured dhcp servers, although it should be a last resort - better to track down the bad DHCP server and fix it.
  • Page 83 9.4.1 Option statements DHCP option statements always start with the option keyword, followed by an option name, followed by option data. The option names and data formats are described below. It is not necessary to exhaustively specify all DHCP options - only those options which are needed by clients must be specified.

Up to 8 Mbits/sec can be sent downstream and 640 Kbits/sec upstream.
  • Page 88 Ethernet address Sometimes referred to as a hardware address. A 48-bits long number assigned to every Ethernet hardware device. Ethernet addresses are usually expressed as 12-character hexadecimal numbers, where each hexadecimal character (0 through F) represents four binary bits. Do not confuse the Ethernet address of a device with its network address.

  • Page 92 D.3 European CTR 21 compliance and CE The equipment has been approved in accordance with Council Decision 98/482/EC for pan-European single terminal connection to the public switched telephone network (PSTN). However, due to differences between the individual PSTNs provided in different countries, the approval does not, of itself, give an unconditional assurance of successful operation on every PSTN network termination point.
