NEW HARDWARE FEATURES
Cisco Catalyst 4500 Series Supervisor Engine II-Plus-10GE
The Cisco Catalyst 4500 Series Supervisor Engine II-Plus-10GE is the next generation Supervisor Engine II-Plus providing added bandwidth
and functionality. Two 10 Gigabit Ethernet and four 1 Gigabit Ethernet uplinks are supported along with enhanced features (e.g. QinQ,
Broadcast/Multicast Suppression). Additionally, please note that the Supervisor Engine II-Plus-10GE will now support Layer 3 routing capabilities
via EIGRP-stub in the 12.2(25)SG IP Base image at no extra cost. Supported on the Cisco Catalyst 4503, 4506, and 4507R, the Supervisor Engine
II-Plus-10GE increases the bandwidth switching capacity up to 108 Gbps at 81 mpps.
Cisco Catalyst 4500 Series 48-Port 100BASE-X, SFP Line Card
The Cisco Catalyst 4500 Series 48-port, nonblocking, 100BASE-X line card provides customers the ability to mix and match various Small Form-
Factor Pluggable (SFP) optics, based on the network need. One to forty-eight 100BASE-X SFP optics can be populated on a single line card, as
100BASE-X SFP optics are optional. In Cisco IOS 12.25(SG) supported SFP optics include FX, LX10, BX-D, and BX-U. This line card is
compatible with any Cisco Catalyst 4500 Series chassis.
NEW SOFTWARE FEATURES
NAC L2 IP
NAC L2 IP is an integral part of Cisco Network Admission Control. It offers the first line of defense for infected hosts (PCs and other devices
attached to a LAN port) attempting to connect to the corporate network. NAC L2 IP on the Cisco Catalyst 4500 Series performs posture validation
at the Layer 2 edge of the network for non-802.1x-enabled host devices. Host device posture validation includes anti-virus state and OS patch levels.
Depending on the corporate access policy and host device posture, a host may be unconditionally admitted, admitted with restricted access, or
quarantined to prevent the spread of viruses across the network.
NAC L2 802.1x
The Cisco Catalyst 4500 Series extends NAC support to 802.1x-enabled devices. Like NAC L2 IP, the NAC L2 802.1x feature determines the level
of network access based on endpoint information.
Time Domain Reflectometry
Time Domain Reflectometry (TDR) is a technology used for diagnosing copper cable state. TDR detects impedance changes along an attached cable
(for example, Category V) to determine opens, shorts, and terminated states. The fault distance from the switch is also supported. TDR is supported
on the following Cisco Catalyst 4500 Series 1000BASE-T hardware products: the Enhanced 48-port 10/100/1000 line card, the 48-port
10/100/1000, 802.3af Power over Ethernet (PoE) line card; the 24-port PoE, 802.3af 10/100/1000 line card; and the Supervisor Engine II-Plus-TS.
TDR is also supported on the Catalyst 4948 and Catalyst 4948-10GE switches.
