Cannot create a PVC between two ONcore hub/CELLplex 4000s located in
different clusters.
Explanation:
This is normal. The ONcore hub/CELLplex 4000 does not allow the creation of
PVCs over network-to-network (NNI) links.
You have created two different PVCs, each one ending at the NNI port.
Note: Make sure that the VPI used by the PVC on the NNI port corresponds to the
one of the logical link defined on that port.
ATM server/token-ring client's applications fail: frames are lost. Token-ring clients
located behind a Token-ring/ATM bridge can connect to an ATM server, but the
applications/sessions keep failing, while clients connected directly to ATM have
no problems.
Explanation: The frame size on the ATM server is larger than the maximum frame
size allowed by the bridge.
Steps to Take:
1. Change the MAX_FRAME_SIZE on the ATM server to the maximum value allowed
by the bridge (8281 max frame size should be 8939 bytes).
Note: You may have to change the MAXDATARCV parameter of the OS/2
token-ring NETBIOS clients to 4168 in the PROTOCOL.INI file.
ONcore hub/CELLplex 4000 Terminal/Telnet very slow or Ping to ONcore
hub/CELLplex 4000 very slow.
Explanation: The ONcore hub/CELLplex 4000 is congested by Signalling Calls.
Steps to Take:
1. If you cannot be in front of the ONcore hub/CELLplex 4000, perform a remote login
using Telnet. First make sure that the trace is not active, then disable the ports one
