New Hardware Features
Cisco Catalyst 4503 Supervisor Engine II-Plus-TS
The Cisco Catalyst 4503 Supervisor Engine II-Plus-TS delivers enterprise-class reliability and security for the medium-sized business. It
provides twelve 10/100/1000 ports with Power over Ethernet (PoE) and eight Small Form-Factor Pluggable (SFP) ports for uplinks or server
aggregation. It works in the Catalyst 4503 chassis to deliver up to 116 ports of any combination of 10/100 and 10/100/1000 data access as well
as 10/100 and 10/100/1000 PoE access.
Cisco Catalyst 4500 Series 6-Port Alternatively Wired 10/100/1000 PoE or SFP Line Card (WS-X4506-GB-T)
The Cisco Catalyst 4500 Series 6-port nonblocking line card provides the flexibility of two connection options per port: 10/100/1000 (IEEE
802.3af and Cisco prestandard PoE) RJ-45 or 1000BASE-X SFP. This line card provides the ability to mix and match interface types without
incurring extra costs.

Stateful Switchover
Stateful switchover (SSO) offers zero interruption to Layer 2 sessions in a redundant supervisor engine configuration on Cisco Catalyst 4507R
and Cisco Catalyst 4510R chassis. Stateful switchover synchronizes changes in switch configuration and Layer 2 protocol/service state
information from the active to the hot standby supervisor engine.
When a failure on the active supervisor engine is detected or if a manual graceful switchover is performed, the hot standby supervisor engine
automatically takes control and becomes the active supervisor engine. Subsecond switchover is achieved through stateful switchover without
causing link flaps.
