Yay vlans

Intro

This blogpost assumes that the switch is fully up to date and that you have cli access.^{(Instructions Here)}.

CLI Commands

This entire blogpost assumes that you have enabled editing.

enable
configure terminal

Creating a VLAN

Command:

vlan <VLAN_ID> name <OPTIONAL_NAME> by port

Note that VLAN 1 is the default VLAN and that ports are implicitly untagged in VLAN 1.

Tagging a interface

Firstly, open the vlan for editing, (it should already be open if you just created the vlan)

vlan <VLAN_ID>

Then tag the interface e.g. Interface 1

tagged ethernet 1/1/1

or an range e.g. Interface 1-5

tagged ethernet 1/1/1 to 1/1/5

Dual-mode (a.k.a. allowing untagged+tagged vlan traffic)

If you want an interface to accept and transmit both tagged/untagged traffic, you will need to set it to dual-mode. Firstly open the interface (e.g. interface 1)

interface ethernet 1/1/1/

Then mark it as dual-mode

dual-mode 1

Note: you can specify a different vlan as the default in dual mode by changing the vlan_id: e.g. dual-mode 10

Conclusion

That's it, if you want to read more in depth, the documentation in the Fastiron Ethernet Switch Platform and Layer 2 Switching guide is quite good, you can find it in Foodeesha' Master Zip here.
