Dshell Commands
The first step in troubleshooting for an 802.1Q problem through Dshell is to verify the configurations.
Validating the configurations in Dshell remove the chances of inconsistency between the CLI and Dshell.
Validating the configurations in Dshell remove the chances of inconsistency between the CLI and Dshell.
Following is the list of commands to verify the configuration of the 802.1Q ports in Dshell. These
commands will verify that there is no inconsistency between the CLI and 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.

The Dshell command print_default_vlan_8021q_cmm shows the default or native VLAN for all of the
802.1Q ports. Slot and port are zero based.

To see the 802.1Q VLANs for a particular port use the print_configured_list_8021q_ni zero_based_port
command as shown below: ???? This command was not marked for deletion but the example below was.
Is this correct and/or is there a new example if this command should stay? ????
