Is it okay to remove VLAN1 from every port?

[kng1]

Hello dear community,

please excuse my beginner question, I have read the protocols like RSTP, LLDP (and others) run over VLAN1, is it still ok if I practically remove VLAN1 everywhere and don't use it at all? Can the switch then still exchange with the other switches about the current STP situation or LLDP etc.?

Best regards,

        - Never remove vlan1 on the switch  , it is always needed for protocols you refer to and others , you can however assign a port to a specific vlan.

Personally i leave the VLAN1(layer2)  in the config, create a New vlan  example 2 and allocated ports to vlan 2 or other vlan.

Execuse me, english is not my first language, I think I badly expressed my question. The question is not that I try to remove it completely but not configure it at all. What I mean by that is not assign any IP, not use it on any tagged or untagged port. Just have it there, my question is does that cause any issue for the Protocols that use VLAN1 such as RSTP, or do they share their information regardless?

sure understand, yes that what i have suggested,  you can leave the VLAN 1 (not required to configure) by default cisco device come with VLAN 1.

For Security reason we always suggest to use new VLAN number (other than 1)

hope that clear ?

L2 Protocol always use VLAN 1
and that why you can never delete it VLAN1

VLAN1 is always active UP and always SW use it to exchange L2 protocol message like CDP/STP/DTP...
