Q. What is the digital signature?
A. The digital signature algorithm (DSA) is present in Cisco Catalyst 6500 (Supervisor Engine 2T only) Cisco
IOS
®
Software packages to detect third-party interception. DSA is a requirement for Federal Information
Processing Standards (FIPS) compliance.
Q. What is the difference between the various software packages?
A. There are four different software packages targeted to requirements in different places of the network,
including campus access, data center access, aggregation, and core.
The following are major feature highlights found in each Cisco IOS Software package:
IP Base: Includes basic routing (Routing Information Protocol [RIP], static routing, Enhanced Interior Gateway
Routing Protocol [EIGRP] Stub, Protocol Independent Multicast [PIM] Stub), Layer 2 capabilities,
manageability, security, IPv6 host support, and quality of service [QoS]).
IP Services: Adds full IP routing (Open Shortest Path First [OSPF], EIGRP, Border Gateway Protocol [BGP],
PIM), Cisco TrustSec
®
security (MacSec*, Secure Group Tagging[SGT]*, SGT Exchange Protocol [SXP], and
Security Association Protocol [SAP]*), Control and Monitoring Processor (CMP)*, and Web Cache
Communication Protocol (WCCP).
Advanced IP Services: Adds advanced IPv4 and IPv6 features, Secure Group Access Control Lists
(SGACLs)*, Layer 3 VPN, Multiprotocol Label Switching (MPLS), EoMPLS, and VPLS.
Advanced Enterprise Services: Full Cisco IOS Software features, including AppleTalk and ATM support.

Q. How do I upgrade from one package to another premium package? For instance, from IP Services to
Advanced IP Services?
A. A customer can upgrade from one package to another premium package using an upgrade CD (part number
6500-SW-SPARECD). If the customer has a Cisco SMARTnet
®
Service contract, that customer still must get
the CD to upgrade the software package.
Q. Can a customer update from one software image to a minor release update version? For instance, from
12.2.(33)SXI2 to 12.2(33)SXI3?
A. Yes, customers can move to the updated version of image if they have a service contract that allows for
software updates such as Cisco SMARTnet.
Q. Can customer upgrade from one major software image to another major release of that image? For instance,
from 12.2.(33)SXI to 12.2(33)SXJ?
A. Yes, customers can move to the upgraded version of image if they have a service contract that allows for
software upgrades such as Cisco SMARTnet.
Q. What is “spare software” or “a software spare” on the Cisco 6500 Series Switches? When do I need to order
one?
A. “Spare” software includes a copy of Cisco IOS Software on a CD-ROM and, most importantly, a license to use
that software. Spare software is required when a customer wants a new version of Cisco IOS Software and
does not have a current maintenance agreement, or when the customer has purchased Cisco 6500 Series
Switches from a third party. Software licenses are not transferable from owner to owner.
