Data Sheet

Nonstop Forwarding with Stateful Switchover (NSF/SSO) offers continuous packet forwarding

during supervisor-engine switchover. Information is fully synchronized between supervisor engines

to allow the standby supervisor engine to immediately take over in subsecond time if the primary

fails. In Service Software Upgrade (ISSU) allows you to upgrade or downgrade complete Cisco

IOS

Software images with minimal to no disruption to the network when using a redundant Cisco

Catalyst 4500 E-Series system with dual supervisor engines. Facilitating rapid, nondisruptive

software upgrade for new line cards, new power supplies, new features, or bug fixes, ISSU offers

continuous packet forwarding during the supervisor-engine switchover running different Cisco IOS

Software releases.

NSF/SSO and ISSU dramatically improve the network reliability and availability in a Layer 2 or

Layer 3 environment. NSF/SSO and ISSU are essential for business-critical applications such as

voice over IP (VoIP). These features help ensure that VoIP calls are not dropped .. NSF/SSO and

ISSU will be supported in the Supervisor Engine 6-E in a Q1 CY’08 Cisco IOS Software release.

Table 4 shows the high-availability and uplink options for the Supervisor Engine 6-E.

IP v6 Support

IPv6 is important for the future of IP networking and is critical for the expansion of IP address

space in the future. IPv6 capability is required by many companies and is being mandated by

governments worldwide. This protocol has been supported on the Cisco Catalyst 4500 Supervisor

Engine II-Plus to V-10GE engines since Cisco IOS Software Release 12.2(20)EW with software

forwarding. The Cisco Catalyst 4500 Supervisor Engine 6-E supports IPv6 Unicast and Multicast in

hardware for full line-rate forwarding performance of up to 125 Mpps. The Supervisor Engine 6-E
