Example: Configuring Link Interfaces on Channelized MICs
Requirements
This example uses the following hardware and software components:
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 Junos OS CLI User Guide.
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:
- CLI Quick Configuration
- 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.
