N2048 setting deletion command

I have a question about the N2048 setting deletion command.

1. I would like to delete some settings that are set on the interface.

Is the following command correct?

no channel-group
no description
no switchport access vlan
no spanning-tree portfast
no switcnport protected


Is it necessary to specify the logical port number or vlan number?

2. If I want to change the description, can I overwrite it by setting a new description without deleting it?

3. Are the following commands used to delete vlans and logical ports?

no vlan [vlan number]

no interface port-channel [channel number]

4. What does the 0 in switcnport protected 0 mean?

    Hi,

     

    Referring to the CLI user guide for N2048: https://dl.dell.com/manuals/all-products/esuprt_ser_stor_net/esuprt_networking/networking-n1100-series_users-guide_en-us.pdf

     

    Page 428: switchport protected
    Page 390: description
    Page 628: channel-group

     

    For switchport protected 0, where 0 denotes the groupID ranged from 0-2

     

    For description, you only issue a 'no description'. 

     

    For channel-grooup, you only issue a 'no channel-group'.

    Hello,

    I hope this formatting comes through. I have answered each line below:

     

    1. I would like to delete some settings that are set on the interface.

    Is the following command, correct?

    no channel-group

    no description

    no switchport access vlan

    no spanning-tree portfast

    no switchport protected

     

    yes, these are correct. Here is from the lab:

    OS6#conf

    OS6(config)#interface Gi1/0/1

    OS6(config-if-Gi1/0/1)#no channel-group

    OS6(config-if-Gi1/0/1)#no switchport access vlan

    OS6(config-if-Gi1/0/1)#switchport protected 0

    OS6(config-if-Gi1/0/1)#no switchport protected

    OS6(config-if-Gi1/0/1)#no spanning-tree  portfast

     

    Is it necessary to specify the logical port number or vlan number?

               
    The “no switchport access vlan” does not require the vlan number in the end

     

    2. If I want to change the description, can I overwrite it by setting a new description without deleting it?
     

              You can set a new description without deleting the old one. It will keep the new one.

              OS6(config-if-Gi1/0/1)#description "TEST"

              OS6(config-if-Gi1/0/1)#description "PORT CONNECTED TO SWITCH2"

            OS6#show running-config interface gi1/0/1

             channel-group 1 mode active

             description "PORT CONNECTED TO SWITCH2"

                           …..

     

    3. Are the following commands used to delete vlans and logical ports?

    no vlan [vlan number]

     

                 This one is done in global configuration mode:

                  OS6#conf

                  OS6(config)#no vlan 200

                  OS6(config)#

     

    no interface port-channel [channel number]

     

    Port channel numbers (in global configuration mode) range from 1 to 128 by default, and you do not delete those (the above command will not work)

    You only delete using “no channel-group” in interface configuration mode, like we showed above. The channel-group command in Interface (Ethernet) Configuration  mode is used to associate a port with a port channel.

     

    4. What does the 0 in switchport protected 0 mean?


    Syntax

    switchport protected groupid

    no switchport protected 

             groupid--Identifies which group this port will be protected in. (Range: 0-2)

    No traffic forwarding is possible between two protected ports. Ports in a protected group will not forward traffic to other ports in the group.

    @DELL-Charles R​ 

    Thank you for your answer.

    If I want to delete "switcnport protected 0",
    do I need to specify up to 0?

    no switcnport protected 0

    Is 0 unnecessary?

    no switcnport protected

    @DELL-Charles R​ 

    Is the following command sufficient to remove the description in N2048?

    no description

    Is a separate description necessary as shown below?

    no description "---coreswitch ---"

    @DELL-Charles R​ 

    On N2048, if I execute the "no channel-group" command in interface configuration mode, will the interface port-channel also disappear from show running-config?
