Introduction

The Cisco MWR 2941 Mobile Wireless Router is a cell-site access platform specifically designed to aggregate and transport mixed-generation radio access network (RAN) traffic. The router is used at the cell site edge as a part of a 2G, 3G, or 4G radio access network (RAN). The Cisco MWR 2941 includes the following models:

Cisco MWR 2941-DC

Cisco MWR 2941-DC-A

The Cisco MWR 2941 router helps enable a variety of RAN solutions by extending IP connectivity to devices using Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Node Bs using HSPA or LTE, base transceiver stations (BTSs) using Enhanced Data Rates for GSM Evolution (EDGE), Code Division Multiple Access (CDMA), CDMA-2000, EVDO, or WiMAX, and other cell-site equipment. It transparently and efficiently transports cell-site voice, data, and signaling traffic over IP using traditional T1 and E1 circuits, as well as alternative backhaul networks such as Carrier Ethernet and DSL, Ethernet in the First Mile (EFM), and WiMAX. It also supports standards-based Internet Engineering Task Force (IETF) Internet protocols over the RAN transport network, including those standardized at the Third-Generation Partnership Project (3GPP) for IP RAN transport. Custom designed for the cell site, the Cisco MWR 2941 features a small form factor, extended operating temperature, and cell-site DC input voltages.

New Hardware Features in Cisco IOS Release 15.1(3)MRA

There are no new hardware features in Cisco IOS Release 15.1(3)MRA.

New Software Features in Cisco IOS Release 15.1(3)MRA

Cisco MWR Release 3.5.1, Cisco IOS Release 15.1(3)MRA introduces the following new software features:

IEEE 802.3ad LACP EtherChannel Support—Enables you to group multiple physical interfaces into a single logical link that provides fault tolerance and redundancy and higher bandwidth. Also known as a type of port channel.

This feature introduces or modifies the following commands:

channel-group—Configures the LAN port in a port channel and specifies the LACP as the unconditional mode of the interface.

lacp fast-switchover—Enables LACP 1:1 link redundancy on this port channel.

lacp max-bundle—Configures the maximum number of member ports that can be in the link-up state and bundled in the EtherChannel for the port channel interface.

lacp min-bundle—Configures the minimum number of member ports that must be in the link-up state and bundled in the EtherChannel for the port channel interface to transition to the link-up state.

lacp port-priority—Sets the priority for a physical interface.

lacp system-priority—Indicates the priority for the system. Higher numbers have lower priority.

show etherchannel load-balance—Displays the load balance and frame distribution scheme across the ports in a port-channel.

show lacp counters—Displays information about the LACP traffic statistics.

show lacp internal [detail]Displays LACP internal information.

show lacp neighbor—Displays information about the LACP neighbor.

show lacp sys-id—Displays the LACP system-id information. It is a combination of the port priority and the MAC address of the device.

ANSI T1.403 Line and Payload Remote Loopback Support—The Cisco MWR 2941 supports the ANSI T1.403 Facility Data Link (FDL) remote loopback (line and payload) initiated at the far end. The FDL carries performance data and control signals across the network interface (NI), the customer installation (CI), and the network.

ANSI T1.403 Line and Payload Loopback support on the Cisco MWR 2941 does not require any configuration tasks on the Cisco MWR 2941 because the FDL remote loopback command initiation is from satellite devices. The Cisco MWR 2941 responds to the instructions from the satellite box and functions as the remote framer in the loopback.

For more detail about these features, including how to configure them on the Cisco MWR 2941, see the Cisco MWR 2941 Release 3.5.1 Software Configuration Guide and Cisco MWR 2941 Release 3.5.1 Command Reference.

Troubleshooting

Caveats in Cisco IOS Release 15.1(3)MRA

The following section describe the caveats open in Cisco IOS Release 15.1(3)MRA.

Open Caveats

CSCua64908

Symptom: Traceback messages are seen after reloading a router on which multilink interfaces are configured or after an IP header compression (IPHC) configuration is changed.

Conditions: Occurs in the following topology:

7600—MWR

The symptom occurs under the following conditions:

Multilink interfaces with IPHC configurations are configured.

The IPHC configurations are changed.

Workaround: None.

CSCua96150

Symptom: SNMP trap-directed notifications occur after every execution of a counter command.

Conditions: This condition occurs after every execution of a counter command when the storm control action trap is enabled and traffic is exceeding the configured limit.

Workaround: None.

CSCub05412

Symptom: The Cisco MWR 2941 does not support storm control for multicast PDUs.

Conditions: Multicast storm control applied as 0% is not controlling the multicast PDUs of CDP and STP. The expected behavior is that when applied as 0% no convergence occurs on STP and no CDP learning occurs.

Workaround: None.

Closed Caveats

CSCub94088 (Duplicate of CSCud02423)

Symptom: Counters increase for all class-maps even though traffic is being sent to only one class-map.

Conditions: The symptom occurs under the following conditions:

10 class-maps with matches on different VLANs are configured.

The service policy is applied on the on the ingress direction of the Cisco MWR 2941.

Traffic is sent from IXIA1 that matches one VLAN class.

When the conditions above occur, the show policy-map interface command displays all the class-map counters increasing.

Workaround: Reload the router.

CSCuc87911

Symptom:

Flags are incorrect when the priority is configured the modes from active to passive change.

Conditions: This condition occurs in the following topology:

IXIA1 > MWR1 > MWR2 > IXIA2

When:

A port-channel interface is configured on the MWR1 and MWR2.

The bundle is up.

The priority is configured and the modes change from active to passive on the members, which results in the incorrect flags. The flags are not correct until the router is reloaded.

The Cisco MWR 2941 does not support dynamic modification of the port-channel mode. Perform a shut and no shut for the flags to be effected post change.

CSCuc88332

Symptom: Deleting a port-channel interface after removing the switchport configuration causes continuous tracebacks to occur.

Conditions: This condition occurs in the following topology:

IXIA1 > MWR1 > MWR2 > IXIA2

When:

A port-channel interface is configured on the MWR1 and MWR2.

The bundle is up.

The switchport configuration is removed from the port-channel interface and as designed, an error message is received.

The port-channel interface is deleted, which causes continuous tracebacks.

The Cisco MWR does not support dynamic modification of the port-channel mode. Perform a shut and no shut for the flags to be affected post change.

CSCuc92958

Symptom: A member of a port-channel takes more time to go to hot-standby mode after its priority has been increased.

Conditions: This condition occurs in the following topology:

IXIA1 > MWR1 > MWR2 > IXIA2

When:

A port-channel interface is configured on the MWR1 and MWR2.

The bundle is up.

The priority of the members is changed, which results in the member of a port-channel taking more time to go to hot-standby mode.

Priority assignment for hot-standby is not supported on the Cisco MWR 2941. The members of a bundle are assigned equal priority.

CSCud37981

Symptom: Tracebacks are seen after shutting the VLAN associated with a port-channel.

Conditions: This condition occurs in the following topology:

IXIA1 > MWR1 > MWR2 > IXIA2

When:

A port-channel interface is configured on the MWR1 and MWR2.

The bundle is up.

The VLAN associated with the port-channel is shut and tracebacks are seen.

Cisco does not recommend performing a shut on a switch VLAN with traffic. The shut vlan command should be replaced with shutdown on the interface VLAN to stop L3 traffic forwarding.

CSCud06690

Symptom: Changes do not take effect when modifying the HQoS policy-map with shaping configured to parent policy-map.

This condition occurs with the following scenario:

When the shaping parameter is modified in the parent policy.

When the parameters are modified/applied in the child policy.

Removing and re-applying the egress service policy from interface makes the changes take effect. For information on removing and reapplying a service policy, see the Cisco MWR 2941 Mobile Wireless Edge Router Software Configuration Guide.
