VLAN configuration

Create new VLAN with description. I’ll be using VLAN 10 for this example.

vlan 10 name "Guest"


Remove VLAN with:

no vlan 10


Assign switch ports 1 through 24 on slot 1 to VLAN 10 using the following command:

vlan 10 port default 1/1-24


for 802.1q (tagged) port use the following command:

vlan 10 802.1q 1/1


You can remove the VLAN port members with the following command:

no vlan 10 port default 1/1-24
no vlan 10 802.1q 1/1


To verify the VLAN 10 configuration, use:

show vlan 10


To verify that ports 1/1-24 were assigned to VLAN 10 use:

show vlan 10 port


Interface Configuration

Show status of all ports:

show interfaces status


Show information about all ports:

show interfaces port


To show information about a specific port only (slot/port):

show interfaces 1/5


Make changes to an interface with the following commands. I’ll be using slot 1 and port 5 in my examples.

Disable auto negotiate (enable or disable):

interfaces 1/5 autoneg disable


Change duplex (full or half):

interfaces 1/5 duplex full


Change interface speed (10,100,1000):

interfaces 1/5 speed 100


Disable or enable a port (up or down):

interfaces 1/5 admin down


Label the ports with:

interfaces 1/5 alias "Specify name here"


Create a management interface

ip interface "mgnt_IP" address mask vlan 3


Verify with:

show ip interface


Remove interface with

no ip interface "mgnt_IP"


Link Aggregation 

Run the following command to create a LACP group for ports 19,20,21 and 22. In this example i’ll be using 2 as the ID, 4 as the size and 5 as the key

lacp linkagg 2 size 4 admin state enable
lacp linkagg 2 actor admin key 5
lacp agg 1/19 actor admin key 5
lacp agg 1/20 actor admin key 5
lacp agg 1/21 actor admin key 5
lacp agg 1/22 actor admin key 5


Now set the VLAN for the LACP group:

vlan 3 port default 2



Start or stop POE on slot 1 (Change slot number accordingly):

lanpower start 1

lanpower stop 1


Start or stop POE on a port (slot/port):

lanpower start 1/5

lanpower stop 1/5
