Statement introduced in Junos OS Release 7.6.
Statement introduced in Junos OS Release 8.4 for J Series Services Routers.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
For Gigabit Ethernet interfaces on M Series, MX Series, T Series, and TX Matrix routers,
explicitly enable autonegotiation and remote fault. For EX Series switches and J Series
Services Routers, explicitly enable autonegotiation only.
—Enables autonegotiation. This is the default.
auto-negotiation
—Disable autonegotiation. When autonegotiation is disabled, you
no-auto-negotiation
must explicitly configure the link mode and speed.
When you configure Tri-Rate Ethernet copper interfaces to operate at 1 Gbps,
autonegotiation must be enabled.
On J Series Services Routers with universal Physical Interface Modules (uPIMs), if the
link speed and duplex mode are also configured, the interfaces use the values configured
as the desired values in the negotiation. If autonegotiation is disabled, the link speed and
link mode must be configured.
Autonegotiation is automatically enabled. No explicit action is taken after the
autonegotiation is complete or if the negotiation fails.
remote-fault (local-interface-online | local-interface-offline)
MX Series, T Series, and TX matrixrouters only, manually configure remote fault on
an interface.
Default: local-interface-online
