Juniper JUNOSE 11.2.X MULTICAST ROUTING, Руководство по настройке

Страница: 192 / 256

This identifier applies to the E120 and E320 routers only. In the software, adapter 0
identifies the right IOA bay (E120 router) and the upper IOA bay (E320 router); adapter
1 identifies the left IOA bay (E120 router) and the lower IOA bay (E320 router).
•
port —Number of the port on the IOA
•
subinterface —Subinterface number of the protocol or VLAN subinterface
For information about installing line modules and IOAs in the E120 and E320 routers, see
E120 and E320 Hardware Guide, Chapter 4, Installing Modules .
Interface Specifier
The configuration task examples in this chapter use the format for ERX7xx models,
ERX14xx models, and the ERX310 router to specify an Ethernet interface. (The format is
described in “Numbering Scheme” on page 169
. )
For example, the following command specifies a Fast Ethernet interface on port 0 of an
I/O module in slot 4.
host1(config)# interface fastEthernet 4/0
When you configure a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface on
E120 or E320 routers, you must include the adapter identifier as part of the interface
specifier. For example, the following command specifies a Gigabit Ethernet interface on
port 0 of the IOA installed in the upper adapter bay of slot 3.
host1(config)# interface gigabitEthernet 3/0/0
For more information about interface types and specifiers on E Series models, see Interface
Types and Specifiers in
JunosE Command Reference Guide .
Fast Ethernet I/O Modules
Fast Ethernet interfaces are supported on two I/O modules: the FE-8 I/O module and
the FE-8 SFP I/O module.
FE-8 I/O Module
ERX7xx models, ERX14xx models, and the ERX310 router all support the FE-8 I/O module.
An FE-8 I/O module accepts up to eight RJ-45 connectors.
FE-8 SFP I/O Module
ERX7xx models, ERX14xx models, and the ERX310 router all support the FE-8 SFP I/O
module.
The FE-8 SFP I/O module uses a range of small form-factor pluggable transceivers
(SFPs) to support different optical modes and cabling distances. The I/O module supports
up to eight LC-style fiber-optic connectors.
Unlike all other Fast Ethernet and Gigabit Ethernet I/O modules, the FE-8 SFP I/O module
does not support automatic negotiation of the line speed and duplex mode by the router.
For more information, see “duplex” on page 192 and “speed” on page 195.
