Chapter 1 Overview of the Cisco 3825 Mobile Wireless Edge Router
New Features in Cisco IOS Release 12.4(16)MR
umts-iub set peering dscp 8
umts-iub local 20.20.20.21 6666
umts-iub remote 20.20.20.20 6666
One new CLI Show command show umts congestion atm slot/port has been added to this feature and
a new field has been added to the show umts-iub peering command (see Appendix A,
“Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference”).
The following example illustrates the use of show umts congestion atm.
Router# show umts congestion atm 0/ima0
UMTS-Iub(ATM0/IMA0):
Congestion: ON
Throttled ATM cells: 415801
Last congestion time: Mar 13 18:09:49.858 duration: 0h 0m 53s
The following example illustrates the use of show atm umts-iub peering command with the new
Congestion Control status field. In this example, it shows it On.
Router# show umts-iub peering atm 0/ima0
UMTS-Iub(ATM0/IMA0): Peering Information
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Local (20.20.20.21:6666) States:
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Connect State: OPEN
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Redundancy State: ACTIVE
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Congestion Control: ON
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Version: 4
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Alarm State:
UMTS-Iub(ATM0/0 - ATM0/2): RX(NO ALARM) TX(NO ALARM)
UMTS-Iub(ATM0/1 - ATM0/3): RX(NO ALARM) TX(NO ALARM)
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Remote (20.20.20.20:6666) States:
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Version: 4
UMTS-Iub(ATM0/IMA0 - ATM0/IMA1): Alarm State:
UMTS-Iub(ATM0/0 - ATM0/2): RX(NO ALARM) TX(NO ALARM)
UMTS-Iub(ATM0/1 - ATM0/3): RX(NO ALARM) TX(NO ALARM)
Inverse Multiplexing over ATM (IMA)Inverse Multiplexing over ATM (IMA) interface as a shorthaul enables you to configure existing UMTS
commands on IMA interfaces. No new commands are added for this new feature. Only previously
existing Cisco IOS commands have been added for this feature (see the “Configuring Inverse
Multiplexing over ATM (IMA)” section on page 4-37 and Appendix A, “Cisco 3825 Mobile Wireless
Edge Router RAN-O Command Reference”).
When operating in the IMA environment, a sample ATM configuration is written as follows:
interface ATM0/0/0
no ip address
no atm ilmi-keepalive
ima-group 0
scrambling-payload
interface ATM0/0/1
no ip address
no atm ilmi-keepalive
ima-group 0
scrambling-payload
