Cisco Catalyst Blade Switch 3020 for HP
This section briefly describes the Cisco Catalyst Blade Switch 3020 for HP and explains how the blade servers within the HP
The Cisco Catalyst Blade Switch 3020 provides enhanced Layer 2 services (known as Layer 2+ or Intelligent Ethernet switching) to the HP
●Loop protection and rapid convergence with support for Per VLAN Spanning Tree Plus (PVST+), IEEE 802.1w, IEEE 802.1s, Bridge Protocol Data Unit (BDPU) Guard, Loop Guard, PortFast, UplinkFast, and Unidirectional Link Detection (UDLD)
●Advanced management protocols, including Cisco Discovery Protocol, VLAN Trunking Protocol (VTP), and Dynamic Trunking Protocol (DTP)
●Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP) for link load balancing and high availability
●Support for authentication services, including RADIUS and TACACS+ client support
●Support for protection mechanisms, such as limiting the number of MAC addresses allowed or shutting down the port in response to security violations
Each Ethernet switch provides eight external Ethernet ports for connecting the blade enclosure to the external network. Four Small
Note: The iLO interface supports a management interface that resides on each server blade. For more information about the iLO system, refer to the “Management” section of this guide.
