Setting Ethernet Port Type
ZoneFlex AP Ethernet ports can be configured as one of the following port types:
■ Trunk Port
■ Access Port
■ General Port
Trunk Port
Trunk Ports forward and receive tagged and untagged frames and are used for
bridging switch ports together. The Trunk port is a member of all VLANs that exist on
the switch, and all VLAN-tagged traffic arriving on the port is seen. If an untagged
frame is received on a Trunk port, the frame is associated with the Untag VLAN (also
known as “native VLAN”, by default, 1).
If a port is configured as a Trunk port, the Untag ID field can be used to define the
Untag VLAN--the VLAN that the switch uses for forwarding/filtering purposes when a
frame arrives without an 802.1Q header.
Access Port
Access Ports are used to provide network access. Traffic arriving on different Access
Ports can be segmented into different logical networks (VLANs) using the Untag VLAN
ID field. Access Ports are members of only one VLAN--the VLAN that is configured in
the Untag VLAN field.
General Port
The General Port can be configured to support multiple tagged VLANs and one
untagged VLAN. As Trunk Ports by definition are members of all VLANs, the General
Port is the only port type for which membership is user configurable.
Insert DHCP
Option 82
When this option is enabled for an Ethernet port, additional
information will be encapsulated in DHCP option 82 and inserted
into DHCP request packets.
Current format of option 82 is:
Circuit ID sub-option: ETH:<IFNAME>:<VLAN>:N/A:
<MODEL>:<HOSTNAME>:<DEVMAC>
This option supports the ability for a service provider to allocate
IP addresses intelligently by considering information on the origin
of the IP allocation request.
