Configuring and Verifying a More Complex Example

The following example makes the following changes from a default configuration:

Sets framing mode to WAN-PHY on the parent interface, and consequently on the unidirectional interfaces as well.
Configures VLAN IDs, VLAN tagging for single VLAN, and IP addresses on both unidirectional interfaces.
Sets a nondefault MAC address on the receive-only interface.
Configures a static ARP entry on the transmit-only interface. The entry contains a MAC address that is put into the Ethernet header destination address field of transmitted frames.

CLI Quick Configuration

To quickly configure the example described, copy the following commands and paste them into the router terminal window:



[edit]

set interfaces xe-5/1/0 framing wan-phy


set interfaces xe-5/1/0 unidirectional 


set interfaces xe-5/1/0-rx mac 00:12:34:56:78:90 


set interfaces xe-5/1/0-rx vlan-tagging unit
102 vlan-id 102 family inet address 10.1.102.2/24 


set interfaces xe-5/1/0-tx vlan-tagging unit
201 vlan-id 201 family inet address 10.2.201.2/24 arp 10.2.201.3 mac
00:ab:cd:cd:ab:cd


set routing-options static route 10.33.1.1/32

The additional logical interfaces for the unidirectional links result from the unit and VLAN tagging configuration.

You can use the show interfaces xe-5/1/0* extensive command to display the most complete set of information about the interfaces. Alternatively, you can specify only xe-5/1/0, xe-5/1/0-rx, or xe-5/1/0-tx to show extensive information about just one interface.

The extensive output includes statistics for the interfaces. The following excerpts show the differences between the receive-only and transmit-only interfaces for statistics.

In the following output for a receive-only interface, input statistics are recorded, but all output statistics have a value of zero.
