originating ATM station. In a network where the number of ATM stations exceeds
256, which is the maximum number of SVCs per 4404B, some stations will not be
able to connect until the bridges clear their SVCs that are unused (aging out
process).
Steps to Take:
1. Wait up to 4 minutes (aging time on the 4404B bridge), or avoid parallel bridging.
LES Monitor: after 3 minutes, the workstation is de-registered from the LES (valid
only for IBM proprietary LAN emulation).
Explanation: The workstation did not send the re-registration message within 3
minutes.
Steps to Take:
1. Ensure that the port for the workstation is connected properly.
2. Ensure that the cable between the ONcore and the workstation is connected
properly.
3. Shutdown, then power off the workstation and restart.
If the problem persists, contact your workstation/adapter supplier.
In a multi Token-ring bridges configuration, a Token-ring bridge cannot register to
the LES. (valid only for IBM proprietary LAN emulation).
Explanation: Different ring numbers are assigned to the ATM ports of two bridges
connected to the same LES.
Steps to Take:
1. Check the ring numbers of the ATM ports of all the bridges attached to the same
LES; these numbers should be equal. Change them if necessary.
