SMC Networks SMC8624/48T manual 142, Assigning Ports to VLANs

CONFIGURING THE SWITCH

This switch supports the following VLAN features:

•Up to 255 VLANs based on the IEEE 802.1Q standard

•Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol

•Port overlapping, allowing a port to participate in multiple VLANs

•End stations can belong to multiple VLANs

•Passing traffic between VLAN-aware and VLAN-unaware devices

•Priority tagging

Assigning Ports to VLANs

Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it will participate. By default all ports are assigned to VLAN 1 as untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more VLANs, and any intermediate network devices or the host at the other end of the connection supports VLANs. Then assign ports on the other VLAN-aware network devices along the path that will carry this traffic to the same VLAN(s), either manually or dynamically using GVRP. However, if you want a port on this switch to participate in one or more VLANs, but none of the intermediate network devices nor the host at the other end of the connection supports VLANs, then you should add this port to the VLAN as an untagged port.

Note: VLAN-tagged frames can pass through VLAN-aware or VLAN-unaware network interconnection devices, but the VLAN tags should be stripped off before passing it on to any end-node host that does not support VLAN tagging.
