3Com 6416SW Installation And User Manual

No Traffic in a Client Environment.Steps to Take:1. Make sure that each LES client does not have more than 12 virtual connections.Problems between two LAN-emulated stations, or between a LAN-emulatedstation and a LAN station located behind a bridge (valid only for IBM proprietaryLAN emulation).Steps to Take:1. For performance problems, first consider the frame sizes defined at the workstationlevel and at the bridge level.2. For connection problems, first consider the Transcend ONcore ATM CampusManager and LAN emulation server, which can provide you with a lot of informationthrough the LES monitor.if you know neither the emulated MAC addresses of the stations nor the ATMaddresses of these stations, use the ATMC Interface Configuration panel to gettheir ATM addresses.Once you know either the ATM addresses or emulated MAC addresses of thestations, look at the Registered End-systems window of the LES monitor andcheck that your stations are registered.Once you know which station is NOT registered, record its ATM address andlook at the Call Status History window of the LES monitor. You should find arecorded call from that ATM address that failed for a certain 'cause X, reason Y'.The cause X shows you the Q2931 cause of the failure. Refer to “Q.2931 ErrorCodes for Clear Causes” on page C-2.If you not find any call from that ATM address, that station has not been able toreach the LES. Use the ATMC Statistics Control Panel to open the Clear Tableof the ONcore/4412SW directly attached to the failing station (select 'Node' and'Call Logging'). That table should have entries with a source ATM address beingthe one of the failing station. You will get a Q2931 cause of the failure. Referto “Q.2931 Error Codes for Clear Causes” on page C-2.7-43
