subinterface sends and receives VLAN-tagged packets, see Layer 2—LAN Switching Configuration
Guide.
• VLAN interface—Virtual Layer 3 interface used for Layer 3 communications between VLANs. Each
VLAN interface corresponds to a VLAN. You can assign an IP address to a VLAN interface and
specify it as the gateway of the corresponding VLAN to forward traffic destined for an IP network
segment different from that of the VLAN.
• Tunnel interface—Virtual Layer 3 interface at the ends of tunnels, which enables devices to transmit
packets through tunnels and recognize and process packets received from tunnels.
• VT interface—Template used for configuring VA interfaces.
• Bridge-aggregation (BAGG) interface—Also known as a "Layer 2 aggregate interface," which
bundles multiple Layer 2 Ethernet interfaces.
• RAGG interface—Also known as a "Layer 3 aggregate interface," which bundles multiple Layer 3
Ethernet interfaces.
• RAGG subinterfaces—Also known as a "Layer 3 aggregate subinterface," which operates in the
network layer and processes Layer 3 protocols. You can assign an IP address to a RAGG
subinterface. A RAGG subinterface receives and transmits VLAN tagged packets on a RAGG
interface.
• Dialer interfaces—Logical interfaces created for dialing services. A physical interface can inherit
the configurations of a dialer interface after it is assigned to the dialer interface. The baud rate of
a dialer interface is always 64000 bps.
You can use the interface management feature to view interface information, create/remove logical
interfaces, change interface status, and reset interface parameters.
NOTE:
Before configuring service functions on an interface, assign the interface to a security zone
(non-management zone).
Managing interfaces in the web interface
Displaying the information and statistics of an interface
1. Select Device Management > Interface from the navigation tree.
The page shows the name, IP address, mask, and status of each interface. The security zone of
Layer 2 Ethernet interfaces is not displayed on the page.
