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 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

  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
