DOWN; LLC interface is UP.
1. DLSw interface
configured on a different slot
than physical interface
2.DLSw interface different
than corresponding LLC

3. Potential LLC problem if
not notifying DLSw that it is
present
1. Check and correct the
configuration to ensure that
DLSw is configured on the
same slot as the physical
interface.
2. Correct the configuration;
DLSw must be configured
on the slot where DLC
termination occurs.
3. Delete LLC interface;
contact Bay Networks.
Ethernet interfaces drop
sessions from Token Ring
interfaces.
Frames sent to Ethernet are
larger than 1500 bytes
Set the DLSw Virtual Ring
MTU parameter on any
routers with Token Ring to
1518 or less
Ethernet sessions establish
with difficulty.
Loops formed by dual router
Ethernet connections
Two DLSw routers
connected to an Ethernet
segment must have filters to
avoid loops.

not come up.
Improper DLS Slot Table
configuration; no IP address
configured on slot
Each slot running DLSw
requires a unique IP
address assigned to each
DLSw slot.
