Port to Default Vlan 1 SG300

[Daniel87]

Hello,

i have a little problem maybe somone can help me.

i have set the last Vlan 1 defaul port to forbidden via web interface, so my switch sg300 is unreachable.

So i connect to the switch witch a console cable and would set one port to the default vlan.

i try so set the port with "switchport mode access" to an access port and then with "switchport access vlan1" to the default vlan, but this failed.

The port can be member of any other vlan i create but not to the default vlan.

Can somone help me how can i set the port as a vlan 1 member, so the switch is reachable over the web interface again?

thank y.

Hi @Daniel87 ,

The vlan 1 is the default vlan (which was not created by a user).

Try set the port with this command:

switchport default-vlan tagged

I hope that you find it useful

Hi luis_cordova,

first i musst set the port as a trunk port to run the command.
As a trunk port the command runs without any error, but the port isnt member of vlan 1.

i will mark the right answer when it works.

Thank y.

Run below commands as:

switchport trunk allowed vlan add 1

switchport trunk native vlan 1

Hallo Deepak Kumar,

i set the port sucessfully with "switchingport mode trunk" as a trunk port

with the command "switchport trunk allowed vlan add 1" it tells me

VLAN 1 : VLAN was not created by user.

The last command "switchport trunk native vlan 1" gives no error, but when i show the port status,

the port isnt member of vlan 1.

Hi,

Ohh, I forget that this is a small-business switch.

You can't make it as allowed VLAN 1 as:

XX_SW(config-if)#switchport trunk allowed vlan add
<2-4094> Specify which VLAN to add to the port.

So run a default command first as:
XX-SW(config-if)#switchport trunk allowed vlan add all

Hi,

i try these command (port is in trunk mode).
"switchport trunk allowed vlan add all"
Message: "An interface cannot become a forbidden VLAN member."
So i think, okay then allow the forbidden Vlan with
"switchport forbidden vlan add 1"
the switch answerd "VLAN was not created by user."

Or is something wrong with the PVID?

here is a working port. (but wrong VLAN for my problem)

Port : gi6
Port Mode: Access
Gvrp Status: disabled
Ingress Filtering: true
Acceptable Frame Type: admitAll
Ingress UnTagged VLAN ( NATIVE ): 100

Port is member in:

Vlan Name Egress rule Added by

Hi,

After seen output which you had shared. I think this is happing due to PVID.

switchport mode general 

no switchport general pvid

switchport general pvid 1
