Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Руководство по настройке

Страница: 204 / 774

For ERX7xx models, ERX14xx models, and ERX310 router, use the
slot / port [. subinterface ] format. For example, the following command specifies a
VLAN subinterface configured on port 0 of an I/O module in slot 4.
host1(config)# interface fastEthernet 4/0.1
For E120 and E320 routers, use the slot / adapter / port [. subinterface ] format, which
includes an identifier for the bay in which the I/O adapter (IOA) resides. For example,
the following command specifies a VLAN subinterface configured on port 0 of the
IOA installed in the upper adapter bay of slot 3.
host1(config)# interface gigabitEthernet 3/0/0.1

Creating a VLAN Subinterface
Ethernet interfaces support IP, PPPoE, MPLS, or both IP and PPPoE on each VLAN.
In addition to a VLAN major interface level, a VLAN subinterface level distinguishes
the VLAN.
NOTE: You cannot configure VLANs on the Fast Ethernet port of the SRP module.
Tasks to configure VLAN subinterface are:
■
“Creating a VLAN Major Interface” on page 172
■
“Configuring IP over VLAN” on page 173
■
“Configuring PPPoE over VLAN” on page 174
■
“Configuring MPLS over VLAN” on page 175
■
“Configuring IP over VLAN and PPPoE over VLAN” on page 176
Creating a VLAN Major Interface
To use VLANs, you must first configure the Ethernet interface for VLAN encapsulation.
This creates the VLAN major interface. For example:
1.
Specify a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet port.
host1(config)# interface fastEthernet 4/0
