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.
VLAN Untag ID: Enter a valid VLAN ID in this field to
segment traffic arriving on this port to a specific
VLAN. Default is 1. Valid VLAN entries are 1-4094.
Members: Displays the VLAN membership of the
port. (Membership is configurable only for the
General port type.)
See “Working with Port-Based VLANs”
on
page 80 for more information.
Insert DHCP Option 82 When this option is enabled for an Ethernet port,
the AP’s base MAC address and device name will
be inserted as the Agent Remote ID sub-option
for DHCP request packets. 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.
