Chapter 18 Configuring MLPPP Backhaul
Note The above configuration has one IMA shorthaul with two member links (atm0/0 and atm0/1).
Configuring T1 and E1 Local Switching
The Cisco MWR 2941 provides support for T1 and E1 local switching. You can use the following
commands to configure T1 and E1 local switching:
• tdm-group—Configures a list of time slots for creating clear channel groups (pass-through) for
time-division multiplexing (TDM) cross-connect.
• connect—Defines connections among T1 or E1 controller ports for drop-and-insert (also called
TDM cross-connect).
Note Local switching is only supported between onboard T1 and E1 ports; local switching between HWIC T1
and E1 ports is not supported.
Note You cannot add a TDM-GROUP to a controller where the CEM-GROUP is defined. Channel-group also
conflicts with CEM-GROUP, which cannot coexist.
Step 9
interface ATMslot/IMA<group-number>
Example:
Router(config-if)# interface
atm0/ima0
Specify the slot location and port of IMA interface group.
• slot—The slot location of the ATM IMA port adapter.
• group-number—The group number of the IMA group.
The example specifies the slot number as 0 and the group number as 0.
Note To explicitly configure the IMA group ID for the IMA interface,
you may use the optional ima group-id command. You cannot
configure the same IMA group ID on two different IMA
interfaces; therefore, if you configure an IMA group ID with the
system-selected default ID already configured on an IMA
interface, the system toggles the IMA interface to make the
user-configured IMA group ID the effective IMA group ID. At the
same, the system toggles the original IMA interface to select a
different IMA group ID.
Step 10
Router(config-if)# no ip address
Disables the IP address configuration for the physical layer interface.
Step 11
Router(config-if)# atm bandwidth
dynamic
Specifies the ATM bandwidth as dynamic.
Step 12
Router(config-if)# no atm
ilmi-keepalive
Disables the Interim Local Management Interface (ILMI) keepalive
parameters.
Step 13
exit
Example:
Router(config)# exit
Router#
Exits configuration mode.
