Problem found. The Physical interfaces are in port-aggregation group, therefore the switchport command is not under the interface. I had to go into the port aggregator group, and into the interface from here, and I will have the switchport command there. When I was checking the running config, this could be shown there, but DELL does not differentiates configuration levels.Let me show it by an example:Current running-config sniplet: port-aggregator group 1add interface Te1/0/1-2interface Gi1/0/1switchport general allowed vlan add 805,811,815,832,842,846,848,852-853A more informative running config, showing which config is part of which config mode: port-aggregator group 1  add interface Te1/0/1-2  interface Gi1/0/1    switchport general allowed vlan add 805,811,815,832,842,846,848,852-853 That way of showing the config would show us the hierarchy of the configuration, and make people's life easier.
I have a task to add more Vlans to an already defined Vlan list on multiple Dell switches.When I go to configure mode, and under the interface, there are no switchport related commands available for me only these: config-if-Gi1/0/30)#? description Add Description to the interfacedo Run Privileged Exec mode commands.dot1x Configure Dot1x interface commands.exit To exit from the mode.show Show configured settings and operational status.shutdown Enable/Disable a port. I am using software version 5.1.3.7 on the switches.Please advice what should I do to configure the ports. Thank you!
