Cisco S49MIPBK9-15002SG= software license/upgrade 1 license(s)

The Enterprise Services image supports all Cisco Catalyst 4500 Series software features based on Cisco IOS Software, including enhanced routing. Customers planning to enable BGP for Supervisor Engine IV, V, or V-10GE will no longer need to purchase a separate BGP license (FR-IRC4) because BGP is included in the Enterprise Services package. Beginning with 12.2(53)SG2, we support the Enterprise Services image on Supervisor Engine 6L-E.

The IP Base image supports Open Shortest Path First (OSPF) for Routed Access and Enhanced Interior Gateway Routing Protocol (EIGRP) "limited" Stub Routing, and RIPv1/v2. The IP Base image does not support enhanced routing features such as Nonstop Forwarding/Stateful Switchover (NSF/SSO), BGP, Intermediate System-to-Intermediate System (IS-IS), Internetwork Packet Exchange (IPX), AppleTalk, Virtual Routing Forwarding (VRF-lite), GLBP, and policy-based routing (PBR).

Cisco IOS Release 12.2(46)SG1 introduced a new LAN Base software and an IP upgrade image. These complement the existing IP Base and Enterprise Services images. The LAN base image is supported on the Supervisor Engine II-Plus-10GE and Supervisor Engine 6L-E starting with Cisco IOS Release 12.2(52)XO. LAN Base image is primarily focused on customer access and Layer 2 requirements and therefore many of the IP Base features are not required. The IP upgrade image is available if at a later date you require some of those features.

Starting with Cisco IOS Release 15.0(2)SG, on the Catalyst 4500 Series Switch, support for NEAT feature has been extended from IP Base to LAN Base and support for HSRP v2 IPV6 has been extended from Enterprise Services to IP Base.
