ASR920-S-A

Description

The Cisco ASR920-S-A license provides the Advanced Metro IP Access feature set for Cisco ASR 920 Series Aggregation Services Routers. This license builds on the Metro IP Access capabilities, adding advanced functionalities such as Multiprotocol Label Switching Transport Profile (MPLS-TP), MPLS, Ethernet over MPLS (EoMPLS), Circuit Emulation Service over Packet Switched Network (CESoPSN), Structure Agnostic TDM over Packet (SAToP) pseudowires, Multirouter Automatic Protection Switching (MR-APS), Multichassis Link Aggregation and Control Protocol (mLACP), MPLS traffic engineering (MPLS TE), MPLS Fast Reroute (MPLS FRR), and MPLS VPN support.

Modular Software Structure

Cisco IOS XE Software for ASR 920 routers features a modular structure that separates the data plane and control plane, enhancing system performance. It supports consolidated packages like Cisco ASR 920 Series IOS XE – No Payload Encryption, with feature sets activated via licenses in a pay-as-you-grow model. Supported from Cisco IOS XE Software Release 3.13.0S.
