This is normal The source or bridge retried to call the destination station with a lower bandwidth bit rate successfully No action required Some ATM stations cannot talk to LAN stations behind PARALLEL bridges Explanation The 4404B bridge has a limitation of 256 ATM connections One would think that multiplying the number of 4404B bridges in parallel would multiply the number of available connections Doing so will lead to the problem that only 256 stations can immediately establish connections with the bridges In a configuration with parallel 4404B bridges bridges registered to the same LAN Emulation Server and connected to the same LAN there may be collisions in terms of connections Indeed when an ATM station calls a LAN station behind the 4404B bridges each 4404B bridge will respond by establishing a connection to the 7 40 ONcore ATM Switch Control Module Installation and User s Guide 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 mes
