ADC SG-1 Manuale Utente
7-9
Example(s)
Using the no interface loopback command
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)
VLAN C
OMMANDS
Configuring the 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

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.
Host(config)# no interface loopback
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.
Host(config)# interface vlan
Note:
The default name value is NULL.
