Juniper JUNOSE 11.2.X MULTICAST ROUTING, Configuration Manual

Page: 214 / 256

•
Use to specify the duplex mode.
•
This command also works on the Fast Ethernet port on the SRP module on all E Series
routers. For more information, see
JunosE System Basics Configuration Guide .
NOTE: If you set either the line speed or duplex mode to automatically negotiate by
using the automatically negotiate keyword, the router negotiates both parameters.
You can specify different values to prevent the router from negotiating these parameters.
Automatic negotiation is not supported for the FE-8 SFP I/O module. For this I/O module,
full duplex mode is the default.
•
Example
host1(config-if)# duplex full
•
Use the no version to revert to the default, either automatically negotiate or full duplex
(FE-8 SFP I/O module only)
•
See duplex.
ethernet description
•
Use to associate a text description of up to 64 characters with an Ethernet interface.
•
This command does not work for the Fast Ethernet port on the SRP module.
•
The description is displayed in the output for show configuration , show interfaces
fastEthernet , show interfaces gigabitEthernet , and show interfaces
tenGigabitEthernet commands.
•
Example
host1(config-if)# ethernet description abcd1234
•
Use the no version to remove the description from the interface.
•
See ethernet description.
interface fastEthernet
•
Use to select a Fast Ethernet interface on a line module.
•
You can also use it to select a Fast Ethernet management port on an SRP I/O module
(ERX7xx models, ERX14xx models, and the ERX310 router) or an SRP IOA (E120 and
E320 routers). For information about managing the Fast Ethernet port on the SRP
module, see
JunosE System Basics Configuration Guide .
•
Use the slot/port [ .subinterface ] format for Fast Ethernet interfaces on ERX7xx models,
ERX14xx models, and the ERX310 router . Use the slot/adapter/port format for the SRP
IOA on the E120 or E320 routers; the port on the SRP IOA is always identified by 0.
•
Example 1—Selects a Fast Ethernet interface on ERX7xx models, ERX14xx models, or
the ERX310 router
host1(config)# interface fastEthernet 1/0
