8.3 VLAN Interfaces
A Virtual Local Area Network (VLAN) divides a physical network into multiple logical networks. The
standard is defined in IEEE 802.1q.
Note: By default, the NXC acts a bridge device. This means all interfaces (ge1~g6) are
grouped together into a single VID, vlan0. Also note that vlan0 cannot be removed
and the VID cannot be changed.
Figure 66 Example: Before VLAN
In this example, there are two physical networks and three departments A, B, and C. The physical
networks are connected to hubs, and the hubs are connected to the router.
Alternatively, you can divide the physical networks into three VLANs.
CAPWAP AC 138 CAPWAP Access Controller addresses option
The Control And Provisioning of Wireless Access Points Protocol allows a
Wireless Termination Point (WTP) to use DHCP to discover the Access
Controllers to which it is to connect. This option carries a list of IPv4 addresses
indicating one or more CAPWAP ACs available to the WTP.
TFTP Server 150 The option contains one or more IPv4 addresses that the client may use. The
current use of this option is for downloading configuration from a VoIP server
via TFTP; however, the option may be used for purposes other than contacting
a VoIP configuration server.
