• 4 external 10/100/1000 Small Form-Factor Pluggable (SFP)-based ports; it supports copper and fiber SX SFP modules
from Cisco Systems®
• 2 external 10/100/1000BASE-T ports

Available with the Cisco IOS® Software LAN Base image, the Cisco Catalyst Blade Switch 3040 offers a complete set of intelligent services to deliver security, quality of service (QoS), and availability in the server farm access environment.
INTELLIGENCE IN THE SERVER ACCESS NETWORK
As companies increasingly rely on the network as the strategic business infrastructure, and with servers having Gigabit Ethernet capabilities, it is more important than ever to consistently help ensure network security, high availability, and QoS-from the server edge out to the clients at the network edge.
Cisco Catalyst switches, including the Cisco Catalyst Blade Switch 3040, enable companies to realize the full benefits of adding intelligent services into their networks. These capabilities make the server network infrastructure:
• Secure to protect confidential information
• Highly available to meet time-critical needs
• Scalable to accommodate future growth
• Capable of differentiating and controlling traffic flows to handle the increasing number of critical business applications
With the wide range of security features that the Cisco Catalyst Blade Switch 3040 offers, businesses can protect important information, keep unauthorized people off of the network, guard privacy, and maintain uninterrupted operation.
To guard against denial-of-service and other attacks, access control lists (ACLs) can be used to restrict access to sensitive portions of the network, blocking unauthorized access to servers and applications by denying packets based on source and destination MAC addresses, IP addresses, or Transmission Control Protocol/User Datagram Protocol (TCP/UDP) ports. ACL lookups are done in hardware, so forwarding performance is not compromised when ACL-based security is implemented.
Port security can be used to limit access on an Ethernet port based on the MAC address of the device to which it is connected. It can also limit the total number of devices plugged into a switch port, reducing the risks of unauthorized servers being plugged into the blade enclosure.
Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) encrypt administrative and network management information, protecting the network from tampering or eavesdropping. TACACS+ and RADIUS authentication enable centralized access control of switches and restrict unauthorized users from altering the configurations. Alternatively, a local username and password database can be configured on the switch itself. Fifteen levels of authorization on the switch console and two levels on the Web-based management interface provide the ability to give different levels of configuration capabilities to different administrators.
The MAC Address Notification feature can be used to monitor the network and track servers by sending an alert to a management station so that network administrators know when and where servers are plugged into or removed from a blade enclosure. The Dynamic Host Configuration Protocol (DHCP) Interface Tracker (Option 82) feature tracks where a server is physically connected on a network by providing both the switch and the port ID to a DHCP server.
The Private VLAN Edge feature isolates ports on a switch, helping to ensure that traffic travels directly from the entry point to the aggregation device through a virtual path and cannot be directed to another port. This can help isolate a server from other servers in the same blade enclosure.
The Cisco Catalyst Blade Switch 3040 offers several high-availability features to minimize network downtime, maintain mission-critical servers and applications, and reduce total cost of ownership.
Enhancements to the standard Spanning Tree Protocol such as Per-VLAN Spanning Tree Plus (PVST+), UplinkFast, and PortFast maximize network uptime. PVST+ allows for Layer 2 load sharing on redundant links to efficiently use the extra capacity inherent in a redundant design. UplinkFast, PortFast, and BackboneFast help reduce the standard 30-second to-60-second Spanning Tree Protocol convergence time. Loop Guard and Bridge Protocol Data Unit (BPDU) Guard provide Spanning Tree Protocol loop avoidance.
Customers can achieve maximum power and cooling availability for a server farm data network when a Cisco Catalyst Blade Switch 3040 uses the redundant power and cooling capabilities of the blade enclosure.
The Cisco Catalyst Blade Switch 3040 offers superior multilayer, granular QoS features to avoid congestion and help ensure that network traffic is properly classified and prioritized. The Cisco Catalyst Blade Switch 3040 can classify, police, mark, queue, and schedule incoming packets and can queue and schedule packets at egress. Packet classification allows the network elements to discriminate between various traffic flows and to enforce policies based on Layer 2 and Layer 3 QoS fields.
To implement QoS, the Cisco Catalyst Blade Switch 3040 first identifies traffic flows or packet groups and classifies or reclassifies these groups using the differentiated services code point (DSCP) field or the 802.1p class-of-service (CoS) field. Classification can be based on criteria as specific as the source/destination IP address, source/destination MAC address, or Layer 4 TCP/UDP port. At the ingress, the Cisco Catalyst Blade Switch 3040 will also police to determine whether a packet is in or out of profile, mark to change the classification label, pass through or drop out of profile packets, queue packets based on classification, and service based on configured weights. Control plane and data plane ACLs are supported on all ports to help ensure proper treatment on a per-packet basis. The Cisco Catalyst Blade Switch 3040 supports four egress queues per port, which allows the network administrator to be discriminating and specific in assigning priorities for the various applications in the server farm. At egress, the switch performs scheduling and congestion control. Scheduling is a process that determines the order in which the queues are processed. The Cisco Catalyst Blade Switch 3040 supports Shaped Round Robin (SRR) and strict priority queuing. The SRR queuing algorithm helps to ensure differential prioritization.
The Catalyst Blade Switch 3040 comes with an embedded GUI device manager that simplifies initial configuration of a switch. Users now have the option to set up the switch through a Web browser. Users familiar with the Cisco command-line interface (CLI) can also use the CLI to do initial configuration and setup. Hence, users do not need any retraining.
Cisco Catalyst Blade Switch 3040 provides for extensive management using SNMP network management platforms such as CiscoWorks for Switched Internetworks. Managed with CiscoWorks, Cisco Catalyst switches can be configured and managed to deliver end-to-end device, VLAN, traffic, and policy management. As part of CiscoWorks, the Web-based Cisco Resource Manager Essentials (RME) offers automated inventory collection, software deployment, easy tracking of network changes, views into device availability, and quick isolation of error conditions.
