Overview
This chapter provides these topics about the switch software:
• Features, page 1-1
• Default Settings After Initial Switch Configuration, page 1-13
• Network Configuration Examples, page 1-16
• Where to Go Next, page 1-20
The term switch refers to a standalone switch and to a switch stack.
In this document, IP refers to IP Version 4 (IPv4) unless there is a specific reference to IP Version 6
(IPv6).
Features
The switch supports either the cryptographic (supports encryption) or the noncryptographic universal
software image. The cryptographic universal software image supports the IP base, IP services, and
advanced IP services feature sets. The noncryptographic universal software image supports only the IP
base and IP services feature sets. You must have a Cisco IOS software license for a specific feature set
to enable it. For more information about the software license, see the Cisco Software Activation for HP
document on Cisco.com.
Some features described in this chapter are only available on the cryptographic software image. You
must obtain authorization to use these features and to download the cryptographic software from
Cisco.com. For more information, see the release notes for this release.
The switch supports one of these feature sets:
• IP base feature set, which provides Layer 2+ features (enterprise-class intelligent services). These
features include access control lists (ACLs), quality of service (QoS), static routing, EIGRP stub
routing, PIM stub routing, the Hot Standby Router Protocol (HSRP), Routing Information Protocol
(RIP), and basic IPv6 management. Switches with the IP base feature set can be upgraded to the IP
services feature set.
• IP services feature set, which provides a richer set of enterprise-class intelligent services. It includes
all IP base features plus full Layer 3 routing (IP unicast routing, IP multicast routing, and fallback
bridging). The IP services feature set includes protocols such as the Enhanced Interior Gateway
Routing Protocol (EIGRP) and the Open Shortest Path First (OSPF) Protocol. This feature set also
supports IPv6 access control lists (ACLs) and Multicast Listener Discovery (MLD) snooping.
Switches with the IP services feature set can be upgraded to the advanced IP services feature set.
IP services-only Layer 3 features are described in the “Layer 3 Features” section on page 1-11.
