Chapter 7: Second Level Commands

Example(s)

Host(config)# interface loopback 1 192.168.3.4 255.255.255.255

Note: When assigning the loopback interface an address that is in the subnet of one of the system interfaces the system should ignore the command and indicates the reason.

Host(config)# interface loopback 1 192.168.3.4 255.255.255.0

The loopback address is not valid.

Using the no interface loopback command

Host(config)# no interface loopback

This command deletes the loopback interface.

Usage

no interface loopback <interface number>

Parameter(s)

<interface number>

This is the loopback interface number to be deleted; valid range is 1 to 200.

Example(s)

Host(config)# no interface loopback 1

Note: The system should refuse to delete a loopback interface if an application source-interface is configured to the loopback.

VLAN COMMANDS

Configuring the VLAN

Host(config)# interface vlan

A virtual (or logical) LAN (called a VLAN) is a local area network with a definition that maps workstations on some basis other than geographic location (for example, by PVC, type of user, or primary application). VLANs are likely to be used with Gigabit Ethernet networks. The SG-1 supports virtual LAN as specified in the IEEE 802.1Q standard. It allows the LAN to be divided into several, disparate LANs and to serve each virtual LAN differently. The SG-1 handles both incoming and outgoing VLAN traffic and supports the full VLAN range (2 - 4095).

The main benefit of using a VLAN is it enables the support of multiple LANs in the same physical interface.

The following command also enables to congigure VLAN on Gigabit Ethernet interface, and also supports QinQ encapsulation in accordance with IEEE 802.1Q

Note: The default name value is NULL.
