Cisco Catalyst 4500 Architecture
Cisco 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

Cisco Catalyst 4500 E-Series Architecture
Centralized Forwarding: 24 Gbps per Slot

9. Switching Module Architecture
IEEE 802.3 Flow Control (Blocking GE Ports)
1.802.3x is an IEEE standards-based mechanism used to control data flow
2.802.3x utilizes pause frames (DA MAC 01-80-C2-00-00-00-0F) to signal flow control
between endstation 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

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
