Runtime Status Codes 80 - Telecommunications link check 83 - Self tests failed 86 - WAN cable disconnected from WAN port 87 - Transmit clock not detected on WAN port 88 - Link down 89 - Link up/Virtual Circuit inactive 91 - Token rings on local and remote bridge have same ring number 92 - Ring number for WAN different on local and remote bridge Blank - Virtual Circuit active The following messages may be displayed from the serial-port monitor. These give information about the bridge operation while it is running. In the first column, the hexadecimal number is the value of the alert that may be displayed through the serial port of the bridge. In the second column: W indicates that the alert is a "warning" and that the bridge will continue to operate without interruption. F indicates a failure alert issued just prior to restarting the bridge. The messages are organized by alert number. 0x0A90 (F) : The 8229 has detected the presence of a cable on the WAN connector. However, the cable identification sense code does not match any supported cable type (EIA 232, X.21, or V.35). Check that the cable is one of the supported types, or replace the cable. 0x0C00 (F) : An internal check for consistency failed. If this repeats, contact your support engineer. 0x0C01 (F) : The bridge detected an error in memory buffer allocation for the WAN port. If this repeats, contact your support engineer. 0x0C02 (F) : The bridge detected an error in memory buffer allocation for the token-ring port or WAN port. If this repeats, contact your support engineer. 0x0C03 thru: Internal frame flow control counts exceeded present limits. 0x0C0A (W) If this repeats, contact your support engineer. 0x0C11 (W) : The token-ring ports on the Frame Relay Bridges at both ends of a WAN circuit are configured with the same ring number. Change one of the ring numbers. 0x0C12 (W) : The Frame Relay Bridges at both ends of a WAN circuit do not agree on the ring number assigned to the virtual ring represented by the WAN circuit. Reconfigure one of the two bridges so that its virtual ring number matches the one for the other bridge. 0x0C13 (F) : Internal token-ring transmission error. If this repeats, contact your support engineer. 0x0C14 (W) : WAN cable was disconnected from the bridge. Reconnect the cable or replace it. 0x0C15 (W) : No transmit clock is being received from the modem/DSU. If the modem/DSU and cable check out OK, contact your WAN service provider. 0x0C16 (W) : A frame has been received from the WAN port with an invalid DLCI (one that does not match the DLCI of the active virtual circuit). If this repeats at an unacceptable rate, contact your frame relay service provider. (The frame will be discarded and operations will continue normally.) 0x0C17 thru: An internal check for consistency failed. If this repeats, 0x0C19 (F) contact your support engineer. 0x0C1A (W) : A full frame was received when a frame fragment was expected. This alert indicates that the WAN is dropping frames. If this repeats at an unacceptable rate, contact your WAN service provider. 0x0C1B (W) : A frame fragment was received when it was not expected. This alert indicates that the WAN is dropping frames. If this repeats at an unacceptable rate, contact your WAN service provider. 0x0C1C (W) : A frame was received on the WAN port with a bad frame check sequence (FCS). This alert may indicate that noise is present on the WAN line. If this repeats at an unacceptable rate, contact your WAN service provider. 0x0C1D (W) : A partial frame was received from the WAN, followed by an intentional abort sequence. In a point-to-point leased line configuration, this alert may indicate that noise is present on the WAN line. If this repeats at an unacceptable rate, contact your WAN service provider. If this occurs when connected to a frame relay service, it is likely that the frame was aborted by the vendor's local frame relay switch. If this repeats, contact your frame relay service provider. 0x0C1E (W) : Data arrived on the WAN interface faster than the bridge could handle it. Since the bridge's performance can easily handle the highest supported WAN speed, this alert may indicate noise on the clock signals between the bridge and the modem/DSU. If this repeats, contact your modem/DSU vendor's support representative. 0x0D01 thru: Internal error in data compression. If this repeats, 0x0D08 (F) contact your support engineer. Bridge Status: Cannot forward the status enquiry The forwarding processor did not forward the frame requested by the control processor. Check the WAN cable and the modem. If they are operational and this repeats, contact your support engineer. Bridge Mode: Switching to Point-to-Point mode This is not an error message. The bridge has auto-detected that it should operate in point-to-point mode based on the physical setup. The following messages may be displayed from the serial-port monitor. These are classified as "informational" messages, which means that they give information about the Frame Relay Network Status. If these messages persist during normal operation, contact your frame relay service provider. FR Network Status: Full Status response not received FR Network Status: Link Integrity response not received A status response was not received from the frame relay network. The link is determined to be inactive if N392 of the last N393 events are in error. The bridge will display a status code 88 on the front LED panel if the link goes down. This message could also occur if the LMI type for the frame relay network and that configured for the bridge do not match. Contact your frame relay service provider to determine the LMI type supported by the network. The bridge supports ANSI T1.617 Annex D and the older LMI Rev1 LMI type.
