Determining DSID to Tunnel Associations
The two commands below are useful for determining the association of DSIDs to DSG tunnels:
show interface cable-downstream <slot>/<port> mdd [raw]
show interface cable-downstream <slot>/<port> cable dsg dcd
The following example is a partial command output that shows tunnel destination MAC to DSID associations:
show interface cable-downstream 14/0 mdd
MDD DSG DA MAC: 0100.0000.0020
DSID: 0x000001
MDD DSG DA MAC: 0100.0000.0040
DSID: 0x000002
MDD DSG DA MAC: 0100.5e34.0081
DSID: 0x000003
MDD DSG DA MAC: 0100.5e34.0085
DSID: 0x000004
MDD DSG DA MAC: 0100.5e35.0017
DSID: 0x000005
MDD DSG DA MAC: 0100.5e35.007b
DSID: 0x000006
The following command can be used to display the tunnel’s destination MAC address in the DSG Downstream Channel
Descriptor (DCD) message:
show interface cable-downstream 14/0 cable dsg dcd
DCD for DChannel 14/0
DCD Fragment Rate: 900ms
DCD Fragment 1 of 1; Cfg change count: 30
