31 | Before You Start | ||
32 | ---------------- | ||
33 | |||
34 | |||
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 | Totol 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. | ||
141 | |||
