host1(config-if)#load-interval 90
Use the no version to restore the default time interval, 300 seconds.
See load-interval.
Use to specify the MTU for an interface.
Specify a value in the range 64–9188 bytes. The range for FE-8 I/O modules is 64–9042
bytes.
This command does not work for the Fast Ethernet port on the SRP module.
Example
host1(config-if)#mtu 9000
Use the no version to specify the default, 1518.
See mtu.
Use to specify the line speed.
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,
the default speed is 100 Mbps.
Example
host1(config-if)#speed 10
Use the no version to revert to the default, either automatically negotiate or 100 Mbps
(FE-8 SFP I/O module only).
See speed.
Use the shutdown command to disable an Ethernet interface.
Use to disable an Ethernet interface.
