Table 1 Description on the fields of debugging dlsw ethernet-backup
Field Description
Sending MP frame from
0007.3f54.909c to
9999.9999.9999
The Ethernet interface with the MAC address of 0007.3f54.909c on
the router is sending an MP frame to multicast address
9999.9999.9999.
neighbour
0007.3ff0.2c12 is
created!
A device configured with the same multicast address is detected on
the LAN. The MAC address of the device is 0007.3ff0.2c12. The
router records the device as its neighbor.
Sending SABME frame
from 0007.3f54.909c to
0007.3ff0.2c12
The router is sending a SABME frame to 0007.3ff0.2c12 for
establishing an LLC circuit.
DISC -> SABMESENT The status of the DLSw Ethernet redundancy circuit changes from
DISC to SABMESENT.
