Introduction

The Cisco ASR 901 Series Aggregation Services 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 RAN.

Cisco IOS Release 15.3(1)S supports the Network Virtualization (nV) feature, which uses the Cisco ASR 901 Series Aggregation Services Router as a satellite to the Cisco ASR 9000 Series Aggregation Services Router. The nV mode of operation is separate from the standard mode of operation of the Cisco ASR 901 router. The features available in the standalone mode are not supported on the nV mode and the features available on the nV mode are not supported on the standalone mode.

Table 1 lists the Cisco ASR 901 router model versions supported in the Cisco IOS Release 15.3(1)S.

None

New Software Features in Release 15.3(1)S

The following feature is supported in the Cisco IOS Release 15.3(1)S:

Network Virtualization

Network Virtualization (nV) is a service that enables you to configure a topology in which one or more Cisco ASR 901 Series Aggregation Services Routers act as satellites to complement one or more Cisco ASR 9000 Series Aggregation Services Routers, to collectively realize a single virtual switching system. In this system, the satellites act under the management control of the Cisco ASR 9000 Series Aggregation Services Router. The complete configuration and management of the satellite chassis and features is performed by the Cisco ASR 9000 router. For more information on Network Virtualization Using Cisco ASR 901 Series Aggregation Services Router as a Satellite guide, go to this URL: http://www.cisco.com/en/US/docs/wireless/asr_901/Reference/guide/nv.html.

Modified Software Features in Release 15.3(1)S

None

Limitations and Restrictions

The Cisco IOS Release 15.3(1)S for the Cisco ASR 901 Series Aggregation Services Router has the following general limitations and restrictions:

Note These restrictions are applicable only for the Cisco IOS Release 15.3(1)S and they may change in future releases. We recommend you to check the release notes of your particular release to see the exact restrictions applicable for the release.

•Local switching on the satellite is not supported. The packets are always sent to the host for layer 2 and layer 3 switching.

•The IC link redundancy is supported only through static EtherChannel. It is not supported through the LACP based link bundles.

•In redundant IC links mode, you cannot configure link bundles of any form (with or without LACP) on the access ports of the same satellite.

•In redundant IC links mode, Ethernet link level features are not supported on the access ports of that satellite. These include LACP and Ethernet OAM (802.3ah).

•In IC link bundle, Link Aggregation Control Protocol (LACP) dependent features such as 1:1 hot standby or min-max links are not supported.

•In-Service Software Upgrade (ISSU) or Minimal Disruptive Restart (MDR) is not supported.

•Only qualified pluggables and SFPs are supported.

•Retrieving inventory or environmental state from a satellite may take a second longer than when retrieved locally on the host.

•You cannot have a link bundle in which some bundle members are satellite Ethernet access ports and other members are local Ethernet ports on the same Cisco ASR 9000 router line card that aggregates the satellite Ethernet bundle members.

•Half-duplex is not supported. You have to configure the speed manually.

Supported Hardware
