  35 Installation
  36 ------------
  37
  38 1. 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
  48 2. [ Removed ]
  49
  50 3. 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
  57 4. 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
  77 5. Ia Driver Configuration
  78
  79 5.1 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
 107 5.2 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
 117 6. 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.
