Configuring VLANs

[kepademus]

Hi,

I'm scratching my head when trying to configure VLANs. I know this is simple question but I'm just starting to learn :)

When I configure new VLANs to switch I lose the connection to the management IP (configuring with SSH connection via network ) immediately after I put the ports to untagged VLAN 10. 

VLAN ID 1 DEFAULT_VLAN

VLAN ID 10  INTRA

VLAN ID 20    VOIP

VLAN ID 30    GUEST

I want the management to be available from VLAN 10. Btw. do I need  VLAN 1 for something?

If by changing the tagging, you are removing the SSH client's visibility of the management address, then that is probably your issue. 

Can you provide :

• Which IP address are you initially SSHing to?
• On which VLAN interface is that IP address?
• Where is the SSH client attached to the network?

Hi,

I believe u gave default vlan your managment ip address. U have to configure vlan 10 also with a managment ip address.

try this:

conf t

vlan 1

ip address <another ip than your wish ip, from the same subnet> <subnetmask>

Now connect to that new ip.

conf t

vlan 10

ip address <your wish ip> <subnetmask>

vlan 10 untagged <portnumber>

if you r connected to that port you r now able to connect via ssh to your swich, if not plug your networkcable to that port and connect.

no you can erase the old vlan 1 ip.

conf t

vlan 1

no ip add

vlan1 cant be deleted, you dont have to use it, just clear every port from vlan1

That was the problem. I figured it out by myself yesterday when I plugged console cable to switch and opened the menu in CLI.
