The IP Base feature set provides baseline enterprise services in addition to all LAN Base features, with 1K VLANs.
IP Base also includes the support for routed access, Stack Power, MACsec, and the new Cisco Service Module.
Stack Power can be deployed in either power sharing mode or redundancy mode.
In power sharing mode, the power of all the power supplies in the stack is aggregated and distributed among the switches in the stack.
The Cisco Catalyst 3750-X Series introduces Cisco Stack Power technology, innovative power interconnect system that allows the power supplies in a stack to be shared as a common resource among all the switches.
Cisco Stack Power unifies the individual power supplies installed in the switches and creates a pool of power, directing that power where it is needed.
In redundant mode, when the total power budget of the stack is calculated, the wattage of the largest power supply is not included.
That power is held in reserve and used to maintain power to switches and attached devices when one power supply fails, enabling the network to operate without interruption.
A working stack can accept new members or delete old ones without service interruption.The IP Services feature set provides full enterprise services that includes advanced Layer 3 features such as Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Protocol Independent Multicast (PIM), and IPv6 routing such as OSPFv3 and EIGRPv6.
