Junos® OS Ethernet Interfaces Configuration ... - Juniper Networks

Routed traffic is forwarded from any port of the multiport Gigabit Ethernet uPIM to the
WAN interface. Switched traffic is forwarded from one port of the multiport Gigabit
Ethernet uPIM to another port on the same the multiport Gigabit Ethernet uPIM. Switched
traffic is not forwarded from a port on one multiport Gigabit Ethernet uPIM to a port on
a different multiport Gigabit Ethernet uPIM. For more information about configuring the
multiport Gigabit Ethernet uPIM switching mode, see the Junos OS System Basics
Configuration Guide.
In access switching mode, only one physical interface is configured for the entire multiport
Gigabit Ethernet uPIM. The single physical interface serves as a Virtual Router Interface
(VRI). Configuration of the physical port characteristics is done under the single physical
interface.
To configure multiport Gigabit Ethernet uPIM Ethernet port properties, include the
switch-port statement at the [edit interfaces ge-pim/0/0] hierarchy level:
[edit interfaces ge-pim/0/0]
switch-options {
switch-port port-number {
(auto-negotiation | no-auto-negotiation);
speed 1g;
link-mode (full-duplex | half-duplex);
}
}
Access switching mode is supported on the 6-port, 8-port, and 16-port Gigabit Ethernet
uPIMs.
The multiport Gigabit Ethernet uPIMs are supported on the J2320, J2350, J4350, and
J6350 Services Routers.
The 6-port and 8-port multiport Gigabit Ethernet uPIM occupies a single slot and can be
installed in any slot. Because the 16-port Gigabit Ethernet uPIM is two slots high, you
cannot install a 16-port uPIM in the top slots (slots 1 and 4). Ports are numbered 0 through
5 on the 6-port Gigabit Ethernet uPIM, 0 through 7 on the 8-port Gigabit Ethernet uPIM,
and 0 through 15 on the 16-port Gigabit Ethernet uPIM.
Example: Configuring J Series Services Router Switching Interfaces
Configure a single physical interface for the uPIM and set the port parameters for port 0
and port 1:
