Configuring Channelized Ports
This section is applicable only when using the CES MDA that supports 4 x T1/E1 ports. CES
MDA is available for use only on the 7210 SAS-M platform in network mode (it cannot be used in
access-uplink mode). It cannot be used on any other 7210 SAS platform.
When configuring channelized ports, the port ID is specified in different ways depending on the
MDA type and level of channelization. Ethernet ports cannot be channelized.
Configuring a Channelized DS1 Card
7210 SAS-M support CES MDA that support 4 port channelized DS-1 cards. The channelization is
as follows:
• N*DS0 in DS1 port.{1..24}
• N*DS0 in E1 port.{1..32}
To make sure you have a channel-capable MDA, verify the MDA-type you are configuring by
entering a show mda slot-id command.
In the following example, MDA 2 shows a channelized DS1 MDA:
In the TDM E1 context, configure DS0 channel groups and their parameters. For a DS1
channelgroup, up to 24 timeslots can be assigned (numbered 1..24). For an E1 channel-group, up
to 31 timeslots can be assigned (numbered 2..32). Only CES services (i.e. CESoPSN and SAToP)
are supported with CES MDA on 7210 SAS-M in network mode.
Configuration Examples follows:
ALA-A>config>port>tdm# e1 1.1
ALA-A>config>port>tdm>e1# channel-group 1
ALA-A>config>port>tdm>e1>channel-group# timeslots 2
ALA-A>config>port>tdm>e1>channel-group# no shutdown
ALA-A>config>port>tdm>e1>channel-group#
ALA-A>config>port>tdm>e1# no shutdown
ALA-A>config>port>tdm>e1# channel-group 2
ALA-A>config>port>tdm>e1>channel-group# timeslots 3
ALA-A>config>port>tdm>e1>channel-group# no shutdown
ALA-A>config>port>tdm>e1>channel-group# exit
ALA-A>config>port>tdm>e1# channel-group 3
ALA-A>config>port>tdm>e1>channel-group# timeslots 11,12
ALA-A>config>port>tdm>e1>channel-group# no shutdown
ALA-A>config>port>tdm>e1>channel-group# exit
ALA-A>config>port>tdm>e1# no shutdown
ALA-A>config>port>tdm>e1# exit
