Enterasys 800-Series Switch VLAN Configurations

We will look for an answer to“How to configure Enterasys VLAN configuration?” on Extreme network Enterasys 800 series switches. In our previous article“Enterasys Configuration – Part 4 [VLAN Configuration]“, we explained VLAN configurations for Enterasys S-Series and C-Series network switches.

If we make VLAN configuration in a structure consisting of 800 series switches with a similar topology, we will see a structure as shown in the picture below. The configuration we will write is very similar to the VLAN configuration commands made in HP Procurve E series network switches.

Enterasys VLAN Configuration:

As can be seen in the structure in the picture, there are two VLANs with C-class IP named VLAN-3 and VLAN-4. In this network, we will only write the configuration for VLAN-3. Since we talked about Tagged (Tagging) and Untagged (Untagging) in our previous article, we will briefly mention them here.

While VLAN IDs are Tagged on the Uplink interfaces where the switches communicate with each other, we will Untagged on the interfaces of the Edge Switches (except uplink ports) where the user computers are located. First, let’s create both VLANs on the Core Switch.

VLAN Creation Commands

CORE Switch:

create vlan <vlan-name> add tag <vlan-id>

create vlan 3 add tag 3

We created VLAN 3 on the 800 series Core Switch. Similarly, let’s create VLAN-3 on the edge switch.

Edge Switch:

create vlan <vlan-name> add tag <vlan-id>

create vlan 3 add tag 3

We have defined VLAN-3 on both Core Switch and Edge Switch. Now let’s perform VLANTagging on the Uplink interfaces of Core Switch and Edge Switch.

Port – Interface VLAN –tagged

CORE Switch:

config vlan <vlan-name> add tagged <port_number>

config vlan 3 add tagged ge.1

Edge Switch:

config vlan <vlan-name> add tagged <port_number>

config vlan 3 add tagged 51

We will perform the Untagged operation on the Client interfaces covering the user ports on the Edge Switch. “We will not perform this operation on the Core Switch” because there are only uplink ports belonging to the Edge Switches on the Core Switch. Only Tagged operation was performed for these ports.

Port – Interface VLAN –untagged

Edge Switch:

config vlan <vlan-name> add untagged <port_number>

config vlan 3 add untagged 1-48  
config vlan 3 add untagged 1,4,16,24,43 
config vlan 3 add untagged 1,3,9,32-48

Finally, port_vlan access definitions must be made on the edge switches for client ports.

Port – Interface Access –port_vlan

Edge Switch:

config port_vlan <port_number> pvid <vlan-id>

config port_vlan 21 pvid 3  

After creating VLAN-4, if“web-management” is open on the edge switch, which is not recommended to leave it open(I recommend managing the switch with SSH or Console procedures), you can also “untagged” as described in the video below.

We created the VLAN-4 network on the Core Switch and Edge switch and communicated the switches and clients. For your questions, please write in the comments section below.
