See + http://www.iphase.com/products/ClassSheet.cfm?ClassID=ATM + for details. + - Only x86 platforms are supported. + - SMP is supported. + + +Before You Start +---------------- + + +Installation +------------ + +1. Installing the adapters in the system + To install the ATM adapters in the system, follow the steps below. + a. Login as root. + b. Shut down the system and power off the system. + c. Install one or more ATM adapters in the system. + d. Connect each adapter to a port on an ATM switch. The green 'Link' + LED on the front panel of the adapter will be on if the adapter is + connected to the switch properly when the system is powered up. + e. Power on and boot the system. + +2. [ Removed ] + +3. Rebuild kernel with ABR support + [ a. and b. removed ] + c. Reconfigure the kernel, choose the Interphase ia driver through "make + menuconfig" or "make xconfig". + d. Rebuild the kernel, loadable modules and the atm tools. + e. Install the new built kernel and modules and reboot. + +4. Load the adapter hardware driver (ia driver) if it is built as a module + a. Login as root. + b. Change directory to /lib/modules/<kernel-version>/atm. + c. Run "insmod suni.o;insmod iphase.o" + The yellow 'status' LED on the front panel of the adapter will blink + while the driver is loaded in the system. + d. To verify that the 'ia' driver is loaded successfully, run the + following command: + + cat /proc/atm/devices + + If the driver is loaded successfully, the output of the command will + be similar to the following lines: + + Itf Type ESI/"MAC"addr AAL(TX,err,RX,err,drop) ... + 0 ia xxxxxxxxx 0 ( 0 0 0 0 0 ) 5 ( 0 0 0 0 0 ) + + You can also check the system log file /var/log/messages for messages + related to the ATM driver. + +5. Ia Driver Configuration + +5.1 Configuration of adapter buffers + The (i)Chip boards have 3 different packet RAM size variants: 128K, 512K and + 1M. The RAM size decides the number of buffers and buffer size. The default + size and number of buffers are set as following: + + Totol Rx RAM Tx RAM Rx Buf Tx Buf Rx buf Tx buf + RAM size size size size size cnt cnt + -------- ------ ------ ------ ------ ------ ------ + 128K 64K 64K 10K 10K 6 6 + 512K 256K 256K 10K 10K 25 25 + 1M 512K 512K 10K 10K 51 51 + + These setting should work well in most environments, but can be + changed by typing the following command: + + insmod <IA_DIR>/ia.o IA_RX_BUF=<RX_CNT> IA_RX_BUF_SZ=<RX_SIZE> \ + IA_TX_BUF=<TX_CNT> IA_TX_BUF_SZ=<TX_SIZE> + Where: + RX_CNT = number of receive buffers in the range (1-128) + RX_SIZE = size of receive buffers in the range (48-64K) + TX_CNT = number of transmit buffers in the range (1-128) + TX_SIZE = size of transmit buffers in the range (48-64K) + + 1. Transmit and receive buffer size must be a multiple of 4. + 2. Care should be taken so that the memory required for the + transmit and receive buffers is less than or equal to the + total adapter packet memory. + +5.2 Turn on ia debug trace + + When the ia driver is built with the CONFIG_ATM_IA_DEBUG flag, the driver + can provide more debug trace if needed. There is a bit mask variable, + IADebugFlag, which controls the output of the traces. You can find the bit + map of the IADebugFlag in iphase.h. + The debug trace can be turn on through the insmod command line option, for + example, "insmod iphase.o IADebugFlag=0xffffffff" can turn on all the debug + traces together with loading the driver. + +6. Ia Driver Test Using ttcp_atm and PVC + + For the PVC setup, the test machines can either be connected back-to-back or + through a switch. If connected through the switch, the switch must be + configured for the PVC(s). + + a. For UBR test: + At the test machine intended to receive data, type: + ttcp_atm -r -a -s 0.100 + At the other test machine, type: + ttcp_atm -t -a -s 0.100 -n 10000 + Run "ttcp_atm -h" to display more options of the ttcp_atm tool. + b. For ABR test: + It is the same as the UBR testing, but with an extra command option: + -Pabr:max_pcr=<xxx> + where: + xxx = the maximum peak cell rate, from 170 - 353207. + This option must be set on both the machines. + c. For CBR test: + It is the same as the UBR testing, but with an extra command option: + -Pcbr:max_pcr=<xxx> + where: + xxx = the maximum peak cell rate, from 170 - 353207. + This option may only be set on the transmit machine. + + +OUTSTANDING ISSUES +------------------ + + + +Contact Information +------------------- + + Customer Support: + United States: Telephone: (214) 654-5555 + Fax: (214) 654-5500 + E-Mail: intouch@iphase.com + Europe: Telephone: 33 (0)1 41 15 44 00 + Fax: 33 (0)1 41 15 12 13 + World Wide Web: http://www.iphase.com + Anonymous FTP: ftp.iphase.com |
