6.7 VLAN Interface Specific Commands

A Virtual Local Area Network (VLAN) divides a physical network into multiple logical networks. The standard is defined in IEEE 802.1q.

In the NXC, each VLAN is called a VLAN interface. As a router, the NXC routes traffic between VLAN interfaces, but it does not route traffic within a VLAN interface.

vlan0 is the default VLAN interface. It cannot be deleted and its VID cannot changed.

Otherwise, VLAN interfaces are similar to other interfaces in many ways. They have an IP address, subnet mask, and gateway used to make routing decisions. They restrict bandwidth and packet size. They can provide DHCP services, and they can verify the gateway is available.

The following table identifies the values required for many of these commands. Other input values are discussed with the corresponding commands.

Table 21 Input Values for VLAN Interface Commands

LABEL

DESCRIPTION

virtual_interface

The VLAN interface name. You may use 0 - 511 alphanumeric

 

characters, underscores (_), or dashes (-), but the first character cannot

 

be a number. This value is case-sensitive.

gateway

The gateway IP address of the interface. Enter a standard IPv4 IP

 

address (for example, 127.0.0.1).

 

 

ip_address

The network mask IP address. Enter a standard IPv4 IP address.

 

 

netmask

The network subnet mask. For example, 255.255.255.0.
