  49. | 1. 09/27/93
  50. |    PROBLEM: -COMM695 on Downstream Workstations.
  51. |             -ACS1231 on Downstream Workstations.
  52. |             -XID failure
  53. |             -Only some Downstream Workstations Connect.
  54. |             -RANDOM COMM695 on Downstream Workstations.
  55. |             -Message LT20030 on the Gateway Workstation
  56. |              in the LANTRAN.LOG.
  57. |             -Cannot establish sessions with more than
  58. |              64 workstations.
  59. |             -ACS0109 OtherLAN error
  60. |    SOLUTION: On the CM SNA GATEWAY workstation, change
  61. |              the following configuration items for the
  62. |              Token-ring card connecting the Downstream
  63. |              workstations:
  64. |
  65. |              -Use the REFERENCE DISKETTE and set the
  66. |               Token-Ring card to use a shared RAM SIZE
  67. |               OF 64K.
  68. |
  69. |              -In the CM configuration for the Token-Ring
  70. |               (SNA) Data Link Control change the Max. number
  71. |               of link stations to 128. (Highest value)
  72. |
  73. |              -In the CM configuration for the Lan Adapter
  74. |               and Protocol support, change the Max. number
  75. |               of link stations to 255. (Highest value)
  76. |
  77. |              -In the LAN adapter and protocol support (LAPS)
  78. |               IEEE 802.2 profile increase the Timer Control
  79. |               Blocks setting to 128.
  80. |
  81. |              -The ACS0109 OtherLAN error is
  82. |               caused by not enough link stations
  83. |               defined for IEEE 802.2.
  84. |               The message ACS0109 is from OTHERLAN
  85. |               (OTRALANF);it usually means that
  86. |               there are not enough link stations
  87. |               for RDSLAN. The formula that you
  88. |               can use to determine if this is the
  89. |               case is:
  90. |
  91. |               (MLS from 802.2) - (MLS from NetBios)
  92. |               - (MLS from DLC Profiles for IBMTRNET)
  93. |               * congestion_tolerance
  94. |
  95. |               Note: MLS stands for
  96. |                     Maximum number of Link Stations
  97. |
  98. |               If this is not greater than 1, then
  99. |               you need to increase the number of
  100. |               link stations for 802.2 or decrease
  101. |               them for NetBios or DLC Profile.
  102. |               You should also be aware that if you
  103. |               change the value on the IEEE 802.2
  104. |               screen for Maximum Number of Link
  105. |               Stations, that the actual value
  106. |               used (which is in the .INI file) may
  107. |               not get changed. To verify the change
  108. |               browse C: IBMCOM CM_Config_file_name.INI

  118. |
  119. | On the CM Gateway, and on one of the failing
  120. | downstream workstations:
  121. |
  122. | Please AUTOSTART the following CM traces:
  123. | Under TRACE SELECTIONS choose:  APPC & IBMTRNET
  124. | Under ADVANCE TRACE SELECTIONS choose:
  125. |       EVENTS 1,2,3,4,5 AND 12.
  126. | Trace record size: 128
  127. | Trace storage size: 16 X 64
  128. | Reference Inforamational APAR II06459.
  129. |
  130. | Stop Communications Manager and in CMLIB sub-directory,
  131. | erase ERROR.DAT and MESSAGE.DAT.
  132. |
  133. | If CM Level 2 requested a trace of the IEE802.2 frames:
  134. |
  135. |   On the CM Gateway and the Downstream workstation add the
  136. |   following trace parameters to the files as listed below.
  137. |   These parameters will start a trace of the IEE802.2 flow.
  138. |
  139. |   In CONFIG.SYS add after the FILES=xxx statement:
  140. |      TRACEBUF=63
  141. |      TRACE=ON 164
  142. |
  143. |   In PROTOCOL.INI under LANDD_nif add after
  144. |   "Bindings = IBMTOK_nif":
  145. |      TRACE = 0x03FE
  146. |
  147. |   In PROTOCOL.INI under NETBEUI_nif add after
  148. |   "Bindings = IBMTOK_nif"
  149. |      OS2TRACEMASK = 0
  150. |
  151. |
  152. | REBOOT THE MACHINE.
  153. |
  154. |
  155. | Recreate the problem.
  156. |
  157. | Stop the traces after the session fails to establish.
  158. |
  159. |   "DS.*" indicates the files are from the Downstream
  160. |          Workstation.
  161. |   "GW.*" indicates the files are from the Gateway
  162. |          Workstation.
  163. |
  164. |   If CM Level 2 requested a trace of the IEE802.2 frames:
  165. |    These commands will stop and save the IEE802.2 trace:
  166. |        On the CM Gateway and the Downstream workstation,
  167. |        in an OS/2 Window enter:
  168. |            TRACE OFF
  169. |            TRACEFMT
  170. |            (Using the pull down menus, save the files as
  171. |             A:"pmr number"DS.802 and A:"pmr number"GW.802)
  172. |
  173. |   On the CM Gateway, copy the CM trace to a file called
  174. |        A:"pmr number"GW.TRC
  175. |
  176. |   On the Downstream workstation, copy the CM trace to a
  177. |   file called
  178. |      A:"pmr number"DS.TRC
  179. |
  180. | Obtain the following Subsystem Management information:
  181. |
  182. |      When the downstream workstation receives the COMM695,
  183. |      on the CM MAIN MENU on the GATEWAY workstation,
  184. |      Chose ADVANCED,
