Dshell
Note. Dshell commands should only be used by Alcatel personnel or under the direction of Alcatel.
Misuse or failure to follow procedures that use Dshell commands in this guide correctly can cause lengthy
network down time and/or permanent damage to hardware.
NI Debug Dshell
Use the gmnSetPrintDestination command from the NiDebug Dshell command to redirect the output of
the group mobility commands to the current session.
-> dshell
Working: [dshell]->NiDebug
6:0 nidbg> gmnSetPrintDestination
6:0 value = 0 = 0x0
All NIs should have a copy of all rules configured on the switch, regardless if that NI has used the rule yet.
To verify that the rules have been loaded on the NI use the gmnShowRules command from the NiDebug
Dshell command. Use the same rule index from above, i.e. 0 = IP net address rule.
-> dshell
Working: [dshell]->NiDebug
6:0 nidbg> gmnShowRules 0
6:0
6:0 NI IP Network Address Rules (2 rules)
6:0 ---------------------------
6:0 net = 5a5a5a00 mask = ffffff00 vid = 90
6:0 net = 3c3c3c00 mask = ffffff00 vid = 60
6:0 value = 0 = 0x0
To verify that the NI sees a port as mobile use the gmnIsPortMobile (port number (zero based))
command from the NiDebug Dshell command. (Please note that 1= mobile and 0=non-mobile.)
-> dshell
Working: [dshell]->NiDebug
6:0 nidbg> gmnIsPortMobile 1
6:0 value = 1 = 0x1
This gmnClassifyDebug command displays group mobility classification process on the NI as the pack-
ets are received. This has to be issued in conjunction with the gmnPrintDestination command to see the
output on the console. This command is issued on the NiDebug prompt for the NI we want to debug.
-> dshell
Working: [dshell]->gmnPrintDestination = 0
Working: [dshell]->gmnClassifyDebug = 1
