Designating Ethernet Port Type
Ethernet ports are defined as one of the following port types:
•
on page 204
•
on page 205
•
on page 205
All three port types are used to define how to manage the following two aspects of VLAN
processing:
• Which VLANs are processed vs. dropped
• What to do with untagged packets (in other words, Native VLAN)
For most ZoneFlex APs, you can set which ports you want to be your Access, Trunk
and General Ports from the ZoneDirector web interface, as long as at least one port on
each AP is designated as a Trunk Port.
NOTE
By default, all ports are enabled as Trunk Ports with Untag VLAN set as 1 (except
for Wall Plate APs, such as ZoneFlex 7055 and H500, whose four front-bottom ports
are enabled as Access Ports by default, and whose rear port is a Trunk Port and is
non-configurable).
If configured as an Access Port, all untagged ingress traffic is sent to the configured
Untag VLAN, and all egress traffic is sent untagged. If configured as a Trunk Port, all
untagged ingress traffic is the configured Untag VLAN (by default, 1), and all VLAN-tagged
traffic on VLANs 1-4094 will be seen when present on the network.
The default Untag VLAN for each port is VLAN 1. Change the Untag VLAN to:
• Segment all ingress traffic on this Access Port to a specific VLAN
• Redefine the Native VLAN on this Trunk Port to match your network configuration
Trunk Ports
Trunk links are required to pass VLAN information between switches. Trunking is a
function that must be enabled on both sides of a link. If two switches are connected
together, for example, both switch ports must be configured as trunk ports. The Trunk
port is a member of all the VLANs that exist on the AP/switch and carries traffic for all
VLANs between switches.
For a Trunk port, the VLAN Untag ID field is used to define the native VLAN - the VLAN
into which untagged ingress packets are placed upon arrival. If your network uses a
different VLAN as the native VLAN, configure the AP Trunk port’s VLAN Untag ID with
the native VLAN used throughout your network.
