LES Monitor: Bridge is on General Multicast Tree, but not on Bridge Multicast
Tree. (valid only for IBM proprietary LAN emulation).
Explanation: The bridge did not send its route descriptors to the LES.
Steps to Take:
1. The bridge is faulty. Contact your 3Com representative.
At workstation reboot: the ATM adapter initialization failed.
Explanation: The switch or concentrator port attached to the workstation is not
enabled, or is not a UNI port.
Steps to Take:
1. From the console, or from the SNMP Manager (ATMC), enable the corresponding
port as a UNI port.
A station cannot register to an LES located behind a WAN (VP-tunnel).
Explanation:
Some of the connections through the VP tunnel work, but not all, especially the
ADD_PARTY to put the stations on the LES Multicast Tree. The ONcore
hub/CELLplex 4000 error-log is full of messages like 'Invalid Message Length'.
The WAN (public network providing the VP-tunnel) uses the VCI=5 for its own
purposes, and there is a conflict with the ONcore hub/CELLplex 4000 which also
uses VCI=5 (ATM-Forum Signalling VCI).
Steps to Take:
1. Ask your public network provider if they use the VCI=5. If necessary, put an ATM
device between the WAN and the ONcore hub/CELLplex 4000 to do the translation
of Signalling VCI to a value other than 5.
