Example: Configuring Link Interfaces on Channelized MICs

Requirements

• Junos OS Release 12.1 or later for MX240, MX480, and MX960 routers
• One MX240, MX480, or MX960 router

Overview

This example provides information about configuring the link interfaces on the following channelized MICs:

• 4-port Channelized SONET/SDH OC3/STM1 (Multi-Rate) MIC with SFP (MIC-3D-4CHOC3-2CHOC12)
• 8-port Channelized SONET/SDH OC3/STM1 (Multi-Rate) MIC with SFP (MIC-3D-8CHOC3-4CHOC12)
• 8-port Channelized DS3/E3 MIC (MIC-3D-8CHDS3-E3-B)

You need to first partition each port on the MICs to configure the link interfaces T1, T3, and DS, and then you configure the link interfaces for bundles. An MLPPP bundle involves "bundling" multiple T1/T3/DS interfaces into a single, logical interface that uses only one IP address. For more information about MLPPP bundles, see Understanding MLPPP Bundles and Link Fragmentation and Interleaving (LFI) on Serial Links. Similarly, you can partition the ports to configure the MICs to the E1/E3 interfaces by setting the framing mode to SDH.

For more information about multilink-based protocols on MX240, MX480, and MX960 routers with Multiservices DPC, see Multilink Interfaces on Channelized MICs Overview.

The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode in the CLI User Guide.

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

Configuration on 4-port Channelized SONET/SDH OC3/STM1 (Multi-Rate) MIC with SFP

To partition each port on the MIC and configure the link interfaces T1, T3, and DS on it and to configure the link interfaces for bundles, perform the following tasks:

• Partitioning Ports on the Channelized MICs and Configuring the Link Interfaces T1, T3, and DS
• Configuring MLPPP, MLFR FRF.15, and MLFR FRF.16 on Link Interfaces for Bundles
• Results

CLI Quick Configuration

To quickly configure synchronization on the aforementioned routers, copy the following commands, paste them in a text file, remove any line breaks, and then copy and paste the commands into the CLI.

Partitioning Ports on the Channelized MICs and Configuring the Link Interfaces T1, T3, and DS

Step-by-Step Procedure

1. Configure the coc12-5/2/0 interface by setting the partition option to 1 with the sublevel interface type set to coc1.
   [edit interfaces]user@host# set coc12-5/2/0 partition 1 interface-type coc1
2. Configure the coc12-5/2/0 interface with the OC-slice range (OC-slice range specifies the bandwidth size required for the interface type you are configuring) set to 1.
   [edit interfaces]user@host# set coc12-5/2/0 partition 1 oc-slice 1
3. Configure the coc12-5/2/0 interface by setting the partition option to 2 with the sublevel interface type set to coc1 and the OC-slice range set to 2.
   [edit interfaces]user@host# set coc12-5/2/0 partition 2 oc-slice 2 interface-type coc1
4. Configure the coc12-5/2/0 interface by setting the partition option to 3 with the sublevel interface type set to coc1 and the OC-slice range set to 3.
   [edit interfaces]user@host# set coc12-5/2/0 partition 3 oc-slice 3 interface-type coc1
5. Configure the coc1-5/2/0:1 interface as a clear channel by setting the no-partition option for the sublevel interface type t3 . (A clear channel consolidates the entire bandwidth of a channelized interface into a single unpartioned stream that looks like a standard interface.)
   [edit interfaces]user@host# set coc1-5/2/0:1 no-partition interface-type t3
6. Configure the coc1-5/2/0:3 interface as a clear channel by setting the no-partition option for the sublevel interface type t3.
   [edit interfaces]user@host# set coc1-5/2/0:3 no-partition interface-type t3
7. Configure the coc1-5/2/0:2 interface by setting the partition option to 1 and 3 with the sublevel interface type set to ct1. Configure the coc1-5/2/0:2 interface by setting the partition option to 2 and 4 with the sublevel interface type set to t1.
   [edit interfaces]user@host# set coc1-5/2/0:2 partition 1 interface-type ct1user@host# set coc1-5/2/0:2 partition 2 interface-type t1user@host# set coc1-5/2/0:2 partition 3 interface-type ct1user@host# set coc1-5/2/0:2 partition 4 interface-type t1
8. Configure the ct1-5/2/0:2:1 interface by setting the partition option to 1 and 2 with the sublevel interface type set to ds. Configure the time slots for the partitions.
   [edit interfaces]user@host# set ct1-5/2/0:2:1 partition 1 timeslots 1 interface-type dsuser@host# set ct1-5/2/0:2:1 partition 2 timeslots 2 interface-type ds
9. Configure a clear channel on the channelized interface ct3-2/0/0 by setting the no-partition option to the sublevel interface type t3 (a clear channel consolidates the entire bandwidth of a channelized interface into a single unpartitioned stream that looks like a standard interface).
   [edit interfaces]user@host# set ct3-2/0/0 no-partition interface-type t3
10. Configure a clear channel on the channelized interface ct3-2/0/0 by setting the partition option to 1, 2, and 3 with the sublevel interface type ds. Configure the ct3-2/0/0 interface by setting the partition option to 4 with the sublevel interface type ct1.
    [edit interfaces]user@host# set ct3-2/0/0 partition 1 interface-type t1user@host# set ct3-2/0/0 partition 2 interface-type t1user@host# set ct3-2/0/0 partition 3 interface-type t1user@host# set ct3-2/0/0 partition 4 interface-type ct1
11. Configure the ct1-2/0/0:4 interface by setting the partition option to 1 and 2 with the sublevel interface type set to ds. Configure the time slots for the partitions.
    [edit interfaces]user@host# set ct1-5/2/0:2:1 partition 1 timeslots 1 interface-type dsuser@host# set ct1-5/2/0:2:1 partition 2 timeslots 2 interface-type ds
