.TH ROUTER.CONF 8 "MARCH 1998" Linux "User Manuals" .SH NAME router.conf \- WANPIPE configuration file .SH DESCRIPTION This is the main router configuration file which defines WAN links and network interfaces to configure WANPIPE drivers. The router.conf file in the /etc directory has to editted to make it specific to the WANPIPE hardware and the protocol being used. The following steps should be followed to ensure proper setup of your WANPIPE driver: .TP 1) Edit [devices] section WANPIPE devices are named 'wanpipeN', where N is 1 to 8. For each adapter installed add a line to the [devices] section as follows: wanpipeN = { .I config_id }, { .I description } where .I config_id is one of the following: .nf WAN_X25 for X.25 link WAN_FR for frame relay link WAN_PPP for PPP link WAN_CHDLC for Cisco HDLC link WAN_BSC for BiSync Streaming API .fi and .I description is an optional description string For example: .nf wanpipe1 = WAN_X.25, X.25 link wanpipe2 = WAN_FR, frame relay link wanpipe3 = WAN_PPP, PPP link wanpipe4 = WAN_CHDLC, Cisco HDLC link wanpipe5 = WAN_BSC, BiSync Streaming API .fi .TP 2) Edit [interfaces] section This section defines the Network interfaces created by the Configure script. For each interface defined add a line to the [interfaces] section as follows: { .I name } = { .I device },{ .I media_addr },{ .I used_by },{ .I description } where: .IP .I name represents name of the interface defined in (/usr/lib/router/interfaces/) .IP .I device represents name of the device (from the [devices] section) this interface is associated with .IP .I media_addr represents media address for this logical channel, if applicable. IF NO MEDIA ADDRESS IS SPECIFIED THEN ENTER A SPACE IN THIS FIELD. .IP .I used_by represents whether the interface is used for WANPIPE or API. ONLY WAN_BSC supports API tag. .IP .I description description of this interface (optional) Media address syntax is device and media specific. The convention is as follows: for X.25 permanent virtual circuit use PVC number in decimal notation for X.25 switched virtual circuit use '@' character followed by the X.25 destination address in decimal notation for Frame relay permanent virtual use DLCI number in decimal notation circuit For example: .IP wan0 = wanpipe1, @123456, WANPIPE, X.25 connection to the branch office 1 (SVC) .IP wan1 = wanpipe1, 1, WANPIPE, X.25 PVC connection to the branch office 2 (PVC) .IP wan2 = wanpipe2, 16, WANPIPE, frame relay connection to the branch office 3 .IP wan3 = wanpipe2, 17, WANPIPE, frame relay connection to ISP .IP < no media address is used > .IP ppp0 = wanpipe3, , PPP , WANPIPE, link to office 1 .IP chdlc0 = wanpipe4, , WANPIPE, Cisco HDLC link to office 2 .IP bsync0 = wanpipe5, , API, Bisync interface for receiving data .TP 3) Edit device private configuration section For each WANPIPE device defined in the [devices] section create a section with the same name, i.e. for the device wanpipe1 create a section [wanpipe1], for the device wanpipe2 create a section [wanpipe2] and so on. This section includes all the card specific parameters with additonal protocol specific parameters if applicable. With this section you can configure all the WANPIPE cards. However for the Integrated CSU/DSU (FT1) boards you MUST also configure them using the FT1 CONFIGURATION UTILITY called cfgft1 found at /usr/sbin directory. The following explains the keywords used in device private configuration section and states whether they are mandatory or optional. It also states which keywords are protocol specific. .IP .I IOPort Adapter's I/O port address. Make sure there is no conflict. (Mandatory for all cards and protocols) .IP .I IRQ Adapter's interrupt request level. Make sure there is no conflict. (Mandatory for all cards and protocol) .IP .I MemAddr Address of the adapter shared memory window. If commented out the memory address is determined automatically. (Optional) .IP .I Firmware Name of the adapter firmware (including path). (Mandatory for all cards) Notice the difference for each PROTOCOL: .IP FRAME RELAY Available options are: .nf For 508 cards: /usr/lib/router/wanpipe/fr508.sfm .fi .IP PPP Available options are: .nf For 508 cards: /usr/lib/router/wanpipe/ppp508.sfm .fi .IP CISCO HDLC Available options are: .nf For 508 cards: /usr/lib/router/wanpipe/chdlc508.sfm .fi .IP X25 Available options are: .nf For 508 cards: /usr/lib/router/wanpipe/x25_508.sfm .fi .IP BiSync Streaming API Available options are: .nf For 502E/503 cards: /usr/lib/router/wanpipe/bstrm502.sfm .fi .IP .I Interface Physical interface type. Available options (508 cards) are: .IP RS232 : RS-232C interface (V.10) .IP V35 : V.35 interface (V.11/RS-422/RS-485/X.21) Does not apply to FT1 cards. .IP .I Clocking Source of the adapter transmit and receive clock signals. Available options are: .IP External : Clock is provided externally (e.g. by the modem or CSU/DSU). Use this for FT1 boards. .IP Internal : Clock is generated on the adapter. When there are two Sangoma Cards back to back set clocking to Internal on one of the cards. .IP .I BaudRate Data transfer rate in bits per second. These values are meaningful if internal clocking is selected. (like in a back-to-back testing configuration) Notice the difference for each PROTOCOL: .IP FRAME RELAY, PPP and CISCO HDLC Typical values are: .nf 9600 9.6 kbps 19200 19.2 kbps 38400 38.4 kbps 56000 56 kbps 64000 64 kbps 128000 128 kbps 1544000 1.544 Mbps (T-1) 2048000 2 Mbps (E-1) .fi .IP X25 Typical values are: .nf 9600 9.6 kbps 19200 19.2 kbps 38400 38.4 kbps 56000 56 kbps 64000 64 kbps 128000 128 kbps .fi .IP .I MTU Maximum transmit unit size (in bytes). This value limits the maximum size of the data packet that can be sent over the WAN link, including any encapsulation header that router may add. It usually has to be not less than the largest MTU of all interfaces configured for this link plus WAN media header size (if any), unless the WAN driver can perform fragmentation of data packets. Notice the difference for each PROTOCOL: .IP FRAME RELAY Note that this also includes header information required for encapsulating higher level protocols such as TCP/IP and IPX. The maximum MTU size supported by the adapter is 4096 bytes. Default value is 1500. .IP X25 This value defines the maximum size of the X.25 data packet. Available options are: .nf 64 128 256 512 1024 .fi Note that X.25 driver provides for packet fragmentation, so that MTUs of the network interfaces using X.25 link can be as large as needed .IP PPP The MTU value specified is used for Local Maximum-Receive-Unit(MRU)/MTU and Minimum Remote MRU. Recommended value for PPP is 1500. .IP CISCO HDLC The MTU value specified is used for Maximum length of the Cisco HDLC data field.Range is 300 - 15354. Recommended value is 1500. .IP .I UDPPORT The UDP port to be used for UDP management by the monitor (explained later). The monitor utilities like fpipemon and pipemon should refer to the udpport defined here. .IP .I Station Notice the difference for each PROTOCOL: .IP FRAME RELAY This parameter specifies whether the adapter should operate as a Customer Premises Equipment (CPE) or emulate a frame relay switch (Access Node). Available options are: .nf CPE CPE mode (default) Node Access Node (switch emulation mode) .fi .IP PPP Does not Apply. .IP CISCO HDLC Does not Apply. .IP X25 This parameter defines whether the adapter should operate as a Data Terminal Equipment (DTE) or Data Circuit Equipment (DCE).

For every interface listed in the [interfaces] section create another section underneath all the private device configuration section. For instance for interface "fr1" create section [fr1], for interface "svc1" create section [svc1] and so on. If these sections are not defined then all the parameters in the section are assigned default value. For FRAME RELAY protocol the following parameter(s) should be added in the interfaces section: .IP .I MULTICAST This parameter either enables or disables discarding packets with a multicast source address. Available options are: .IP YES Do not discard packets with a multicast source addr. .IP NO Discard packets with a multicast source addr. Default is set to NO. .IP .I CIR This parameter enables or disables Committed Information rate on the board. Options are 1 - 512 kbps. PLEASE NOTE THAT THIS VALUE REFERS TO ONLY TRANSFERING DATA PACKETS. If this parameter is commented out then CIR for that interface is disabled. .IP .I BC This paramater states the Committed Burst Size. Options are 1 - 512 kbits. .IP .I BE This parameter states the Excess Burst Size. Options are 0 - 512 kbits. .IP .I INARP This parameter enables or disables transmission of Inverse Arp packets. .IP .I INARPINTERVAL This parameter sets the time interval in seconds between Inverse ARP Request. Default is 10 sec For X25 protocol the following parameter(s) should be added in the interfaces section: .IP .I IDLETIMEOUT The time in seconds before an SVC will disconnect if there is no data over the link. The default is 90 seconds. .IP .I HOLDTIMEOUT The time in seconds to wait before retrying a failed connection. The default is 10 seconds. For PPP protocol the following parameter(s) should be added in the interfaces section: .IP .I MULTICAST This parameter either enables or disables discarding packets with a multicast source address. Available options are: .IP YES Do not discard packets with a multicast source addr. .IP NO Discard packets with a multicast source addr. Default is set to NO. .IP .I PAP This parameter enables or disables the use of PAP. Available options are: .IP YES Enable PAP .IP NO Disable PAP This option is needed regardless of the station being an AUTHENTICATOR. .IP .I CHAP This parameter enables or disables the use of CHAP. Available options are: .IP YES Enable CHAP .IP NO Disable CHAP This option is needed regardless of the station being an AUTHENTICATOR. .IP .I USERID This parameter is dependent on the AUTHENTICATOR parameter. If AUTHENTICATOR is set to NO then you will simply enter in your login name that the other side specified to you. If AUTHENTICATOR is set to YES then you will have to maintain a list of all the users that are valid for authentication purposes. If your list contains ONLY ONE MEMBER then simply enter in the login name. If the list contains more than one member then follow the below format: USERID = LOGIN1 / LOGIN2 / LOGIN3....so on The "/" separators are VERY IMPORTANT if you have more than one member to support. .IP .I PASSWD This parameter is dependent on the AUTHENTICATOR parameter. If AUTHENTICATOR is set to NO then you will simply enter in your password for the login name that the other side specified to you. If AUTHENTICATOR is set to YES then you will have to maintain a list of all the passwords for all the users that are valid for authentication purposes. If your list contains ONLY ONE MEMBER then simply enter in the password for the corresponding login name in the USERID parameter. If the list contains more than one member then follow the format below: PASSWD = PASS1 / PASS2 / PASS3....so on The "/" separators are VERY IMPORTANT if you have more than one member to support. The ORDER of your passwords is very important. They correspond to the order of the userids. .IP .I SYSNAME This parameter is dependent on the AUTHENTICATOR parameter. If AUTHENTICATOR is set to NO then you can simply ignore this parameter. (comment it ) If AUTHENTICATOR is set to YES then you have to enter Challenge system name which can be no longer than 31 characters. .SH FILES .TP .I /etc/router.conf Configuration file for WANPIPE .TP .I /usr/lib/router/samples/router.conf Sample Configuration file for WANPIPE .SH AUTHOR .I Jaspreet Singh
