Catalyst 4500 E-Series with CenterFlex Technology-Technical Deep Dive
Agenda1. Catalyst 4500 Centralized Architecture2. Catalyst 4500 E-Series Overview3. Technical Deep Dive–TCAMS–QoS–HA/Management–Multicast
Cisco Catalyst 4500 ArchitectureCisco Catalyst 4500 Utilizes a Centralized Architecture Cisco Catalyst 4500 is a shared memory switch All forwarding, queuing, security is implemented on the Supervisor The individual line cards are considered to be ‘transparent’
-Contain simple “stub” ASICs and the PHY‘s-No local switching
Each classic line card has 6 Gbps (full duplex) connections to the central forwarding engine
E-Series line cards have a 24 Gbps (full duplex) connection to the central forwarding engine
Evolution of Centralized Switching Technology

Catalyst 4500 Compatibility and Flexibility Maximizing Investment
Cisco Catalyst 4500 Classic ArchitectureCentralized Forwarding: 6 Gbps per Slot
Cisco Catalyst 4500 E-Series ArchitectureCentralized Forwarding: 24 Gbps per Slot
Switching Module ArchitectureIEEE 802.3 Flow Control (Blocking GE Ports)1.802.3x is an IEEE standards-based mechanism used to control data flow2.802.3x utilizes pause frames (DA MAC 01-80-C2-00-00-00-0F) to signal flow control between end station and switch 3. Flow control operation steps Data flows to switch Switch congested so “pause” frame sent End station waits required time before sending
Cisco Catalyst 4500 supervisors support both Tx and Rx pause frames
Cisco Catalyst 4500 E-Series: CenterFlexCatalyst 4500 Sup 6-E Technical Deep Dive
Catalyst 4500 Offers Higher Feature Capacity
Dedicated hardware capacity for forwarding Dedicated hardware capacity for features Ample headroom for future requirements Line rate performance for security and QoS
Scalable and Flexible Services Capacity

CenterFlex Enabled TCAM 4 Flexibility
Cisco Catalyst 4500 E-Series-IPv4 and IPv6 Support
Centralized architecture allows for easier upgrades Example: TCAM 4-based hardware lookups provide dynamic table sizing for IPv4
to IPv6 migration Upgrade the supervisor in a classic 4500 chassis to get IPv6 in HW and other
capabilities
CenterFlex Enabled Dynamic Configuration
Optimized Space Allocation for IPv4 and IPv6 Configurations! Hardware Support for IPv6
