Example: Configure Framing Mode for Synchronous Ethernet with 10-Gigabit Ethernet MIC

This example uses the following hardware and software components:

• Junos OS Release 11.4 or later for MX240, MX480, or MX960 routers

• One MX240, MX480, and MX960 router with 10-Gigabit Ethernet MIC with XFP

You can set the framing mode at the PIC level and at the interface level with various configuration combinations. For more information about the various configuration combinations, see Synchronous Ethernet on 10-Gigabit Ethernet MIC.

This example provides information about configuring framing mode at the interface level and the PIC level for Synchronous Ethernet on the 10-Gigabit Ethernet MIC with XFP.

The 10-Gigabit Ethernet MIC with XFP supports Synchronous Ethernet in LAN-PHY framing mode. This is possible only when all the logical PICs under the given Modular Interface Card (MIC) and its ingress interfaces are configured in LAN framing mode.

You can also alternatively configure a MIC in WAN-PHY framing mode on MX80, MX240, MX480, and MX960 routers by configuring all the constituent logical PICs in the same WAN-PHY framing mode in any one of the following configurations:

• No framing mode configured on all the constituent logical PICs of the MIC.

• Incompatible framing mode configured on constituent logical PICs of the MIC.

• No framing mode configured on some of the constituent logical PICs of the MIC.

By default, the PIC-level framing mode is set to WAN framing type, that is e1 | e3 | sdh | sonet | t1 | t3. Synchronous Ethernet works on 10-Gigabit Ethernet MIC with XFP in LAN-PHY mode only when the PIC level framing configuration is configured to lan framing type explicitly.

By default, the interface-level framing mode is set to lan-phy. For WAN-PHY operation, interface framing needs to be set to wan-phy framing explicitly.

You can set the values for each parameter according to your requirement. The values given in this example are for illustration purposes only.
