Configuring Cisco HDLC on a channelized port

Use the following CLI syntax to configure cHDLC:

config# port port-id 
    — tdm
        — ds3 [sonet-sdh-index]
            — channelized {ds1|e1}
            — no shutdown
        — ds1 
            — channel-group channel-group
                — cisco-hdlc
                    — down-count down-count
                    — keepalive time-interval
                    — up-count up-count
                — encap-type {bcp-null|bcp-dot1q|ipcp|ppp-auto|frame-relay|wan-mirror|cisco-hdlc}
                — timeslots timeslots
                — no shutdown

The following example shows SONET/SDH access mode configuration command usage:

A:ALA-29>config>port>tdm# ds3
    — A:ALA-29>config>port>tdm>ds3# channelized ds1
    — A:ALA-29>config>port>tdm>ds3# no shutdown
    — A:ALA-29>config>port>tdm>ds3# exit
    — A:ALA-29>config>port>tdm# ds1 1
    — A:ALA-29>config>port>tdm>ds1# no shutdown
    — A:ALA-29>config>port>tdm>ds1# channel-group 1
    — A:ALA-29>config>port>tdm>ds1>channel-group# timeslots 1-20
    — A:ALA-29>config>port>tdm>ds1>channel-group# encap-type cisco-hdlc
    — A:ALA-29>config>port>tdm>ds1>channel-group# exit
    — A:ALA-29>config>port>tdm>ds1# channel-group 1
    — A:ALA-29>config>port>tdm>ds1>channel-group# no shutdown
    — A:ALA-29>config>port>tdm>ds1>channel-group# exit
    — A:ALA-29>config>port>tdm>ds1# exit
    — A:ALA-29>config>port>tdm#

The following example shows a configuration:

A:ALA-29>config>port# inf
