See 25 http://www.iphase.com/ 26 for details. 27 - Only x86 platforms are supported. 28 - SMP is supported. 29 30 31Before You Start 32---------------- 33 34 35Installation 36------------ 37 381. Installing the adapters in the system 39 To install the ATM adapters in the system, follow the steps below. 40 a. Login as root. 41 b. Shut down the system and power off the system. 42 c. Install one or more ATM adapters in the system. 43 d. Connect each adapter to a port on an ATM switch. The green 'Link' 44 LED on the front panel of the adapter will be on if the adapter is 45 connected to the switch properly when the system is powered up. 46 e. Power on and boot the system. 47 482. [ Removed ] 49 503. Rebuild kernel with ABR support 51 [ a. and b. removed ] 52 c. Reconfigure the kernel, choose the Interphase ia driver through "make 53 menuconfig" or "make xconfig". 54 d. Rebuild the kernel, loadable modules and the atm tools. 55 e. Install the new built kernel and modules and reboot. 56 574. Load the adapter hardware driver (ia driver) if it is built as a module 58 a. Login as root. 59 b. Change directory to /lib/modules/<kernel-version>/atm. 60 c. Run "insmod suni.o;insmod iphase.o" 61 The yellow 'status' LED on the front panel of the adapter will blink 62 while the driver is loaded in the system. 63 d. To verify that the 'ia' driver is loaded successfully, run the 64 following command: 65 66 cat /proc/atm/devices 67 68 If the driver is loaded successfully, the output of the command will 69 be similar to the following lines: 70 71 Itf Type ESI/"MAC"addr AAL(TX,err,RX,err,drop) ... 72 0 ia xxxxxxxxx 0 ( 0 0 0 0 0 ) 5 ( 0 0 0 0 0 ) 73 74 You can also check the system log file /var/log/messages for messages 75 related to the ATM driver. 76 775. Ia Driver Configuration 78 795.1 Configuration of adapter buffers 80 The (i)Chip boards have 3 different packet RAM size variants: 128K, 512K and 81 1M. The RAM size decides the number of buffers and buffer size. The default 82 size and number of buffers are set as following: 83 84 Total Rx RAM Tx RAM Rx Buf Tx Buf Rx buf Tx buf 85 RAM size size size size size cnt cnt 86 -------- ------ ------ ------ ------ ------ ------ 87 128K 64K 64K 10K 10K 6 6 88 512K 256K 256K 10K 10K 25 25 89 1M 512K 512K 10K 10K 51 51 90 91 These setting should work well in most environments, but can be 92 changed by typing the following command: 93 94 insmod <IA_DIR>/ia.o IA_RX_BUF=<RX_CNT> IA_RX_BUF_SZ=<RX_SIZE> \ 95 IA_TX_BUF=<TX_CNT> IA_TX_BUF_SZ=<TX_SIZE> 96 Where: 97 RX_CNT = number of receive buffers in the range (1-128) 98 RX_SIZE = size of receive buffers in the range (48-64K) 99 TX_CNT = number of transmit buffers in the range (1-128) 100 TX_SIZE = size of transmit buffers in the range (48-64K) 101 102 1. Transmit and receive buffer size must be a multiple of 4. 103 2. Care should be taken so that the memory required for the 104 transmit and receive buffers is less than or equal to the 105 total adapter packet memory. 106 1075.2 Turn on ia debug trace 108 109 When the ia driver is built with the CONFIG_ATM_IA_DEBUG flag, the driver 110 can provide more debug trace if needed. There is a bit mask variable, 111 IADebugFlag, which controls the output of the traces. You can find the bit 112 map of the IADebugFlag in iphase.h. 113 The debug trace can be turn on through the insmod command line option, for 114 example, "insmod iphase.o IADebugFlag=0xffffffff" can turn on all the debug 115 traces together with loading the driver. 116 1176. Ia Driver Test Using ttcp_atm and PVC 118 119 For the PVC setup, the test machines can either be connected back-to-back or 120 through a switch. If connected through the switch, the switch must be 121 configured for the PVC(s). 122 123 a. For UBR test: 124 At the test machine intended to receive data, type: 125 ttcp_atm -r -a -s 0.100 126 At the other test machine, type: 127 ttcp_atm -t -a -s 0.100 -n 10000 128 Run "ttcp_atm -h" to display more options of the ttcp_atm tool. 129 b. For ABR test: 130 It is the same as the UBR testing, but with an extra command option: 131 -Pabr:max_pcr=<xxx> 132 where: 133 xxx = the maximum peak cell rate, from 170 - 353207. 134 This option must be set on both the machines. 135 c. For CBR test: 136 It is the same as the UBR testing, but with an extra command option: 137 -Pcbr:max_pcr=<xxx> 138 where: 139 xxx = the maximum peak cell rate, from 170 - 353207. 140 This option may only be set on the transmit machine. 141 142 143OUTSTANDING ISSUES 144------------------ 145 146 147 148Contact Information 149------------------- 150 151 Customer Support: 152 United States: Telephone: (214) 654-5555 153 Fax: (214) 654-5500 154 E-Mail: intouch@iphase.com 155 Europe: Telephone: 33 (0)1 41 15 44 00 156 Fax: 33 (0)1 41 15 12 13 157 World Wide Web: http://www.iphase.com 158 Anonymous FTP: ftp.iphase.com 159
