Configuring Bundle Protection Group Ports

Bundle Protection groups enable APS protection of one bundle residing on a working circuit of an APS group port by another bundle residing on the protection circuit of that APS group port. Bundle protection groups apply to MLPPP as well, and are configured the same way. The following examples show the process to configure BPGrp on ASAP MDAs to provide an APS protection for an IMA/MLPPP bundle.

First, two ASAP MDAs must be configured.

config# card 3
    config>card# mda 2
    config>card>mda# mda-type m4-choc3-as-sfp
    config>card>mda# no shutdown
    config>card>mda# exit
    config>card# exit
    config# card 10
    config>card# mda 2
    config>card>mda# mda-type m4-choc3-as-sfp
    config>card>mda# no shutdown
    config>card>mda# exit

Configure an APS group with working and protection circuits on the ASAP MDAs.

config# port aps-1
    — config>port# aps
    — config>port>aps# working-circuit 3/2/1
    — config>port>aps# protect-circuit 10/2/1
    — config>port>aps# exit
    — config>port# no shutdown

Create eight ATM DS1 channels on the APS group.

config>port>aps# 
    — config>port# sonet-sdh
    — config>port>sonet-sdh# path sts1-1
    — config>port>sonet-sdh>path# no shutdown
    — config>port>sonet-sdh>path# exit
    — config>port>sonet-sdh# exit
    — config>port# tdm
    — config>port>tdm#
    — config>port>tdm# ds3 1
    — config>port>tdm>ds3# channelized ds1
    — config>port>tdm>ds3# no shutdown
    — config>port>tdm>ds3# exit
    — config>port>tdm# ds1 1.1
    — config>port>tdm>ds1# channel-group 1
    — config>port>tdm>ds1>channel-group# encap-type atm 
    — config>port>tdm>ds1>channel-group# no shutdown
    — config>port>tdm>ds1>channel-group# exit
    — config>port>tdm# ds1 1.8
    — config>port>tdm>ds1# channel-group 1
    — config>port>tdm>ds1>channel-group# encap-type atm 
    — config>port>tdm>ds1>channel-group# no shutdown
    — config>port>tdm>ds1>channel-group# exit

Next, configure an IMA-type/MLPPP-type BPGrp with working and protection bundles on working and protection circuits of aps-1 and members the created DS1s (this creates 2 IMA bundles, one on working and one on protection circuit):

config# port bpgrp-ima-1
    — config>port# multilink-bundle
    — config>port>multilink-bundle# working-bundle bundle-ima-1/1.1
    — config>port>multilink-bundle# protect-bundle bundle-ima-2/1.1
    — config>port>multilink-bundle# member aps-1.1.1.1
    — config>port>multilink-bundle# member aps-1.1.2.1
    — config>port>multilink-bundle# member aps-1.1.3.1
    — config>port>multilink-bundle# member aps-1.1.4.1
    — config>port>multilink-bundle# member aps-1.1.5.1
    — config>port>multilink-bundle# member aps-1.1.6.1
    — config>port>multilink-bundle# member aps-1.1.7.1
    — config>port>multilink-bundle# member aps-1.1.8.1
    — config>port>multilink-bundle# exit
    — config>port>multilink-bundle# no shutdown
    — config>port>multilink-bundle# exit
    — config>port# no shutdown

Finally, a service can be configured on this bundle using the BPGrp ID (for example, an ATM VC 0/32 SAP would be: sap bpg-ima-1:0/32).
