Removing port from a VLAN

  • configure vlan <vlan_name> delete ports <port_list>
  • configure vlan <vlan_id> delete ports <port_list>

How to delete a VLAN

configure vlan <vlan_name> delete ports all
delete vlan <vlan_name>

Show VLAN information

  • show port vlan
  • show vlan
  • show vlan <vlan_name>
  • show fdb

Add IP address to a VLAN

configure vlan <vlan_name> ipaddress <ip_address>/<subnet_mask

Remove IP address from a VLAN

unconfigure vlan <vlan_name> ipaddress


Creating Dynamic VLANs

To specify one or more ports as tagged uplink ports that are added to the dynamically created VLAN, use the following command:

configure netlogin dynamic-vlan uplink-ports [port_list | none]

To enable the switch to create dynamic VLANs, use the following command:

configure netlogin dynamic-vlan [disable | enable]
