Figure 1. Cisco Catalyst Blade Switch 3032 for Dell M1000e
The Cisco Catalyst Blade Switch 3032 for Dell M1000e provides Dell M1000e customers with an integrated switching solution that dramatically reduces cable complexity. This solution offers consistent network services such as high availability, quality of service (QoS), and security. It uses the comprehensive Cisco management framework to simplify ongoing operations. Cisco advanced network services in combination with simplified management help reduce total cost of ownership (TCO).
The Cisco Catalyst Blade Switch 3032 for Dell M1000e provides the following hardware configuration:
• 16 internal 1000BASE ports connected to servers through the Dell M1000e backplane
• Up to 8 Gigabit Ethernet uplink ports: 4 10/100/1000BASE-T ports and 4 Small Form-Factor Pluggable (SFP) Gigabit Ethernet ports (using Cisco TwinGig Converter Modules in the X2 slots)
• One external console port
Available with Cisco IOS
® Software, with the IP Base image, the Cisco Catalyst Blade Switch 3032 offers a complete set of intelligent services to deliver security, QoS, basic IP routing, and high availability in the server farm access environment.
Features and Benefits
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 try to ensure network security, high availability, and QoS from the server edge to the clients at the network edge.
Cisco Catalyst switches, including the Cisco Catalyst Blade Switch 3032, enable companies to realize the full benefits of adding intelligent services to their networks. These capabilities make the server network infrastructure:
• Secure, to protect confidential information
• Highly available, to meet on time-critical needs
• Capable of differentiating and controlling traffic flows to handle the increasing number of critical business applications
• Easily manageable, to reduce operational expenses
With the wide range of security features that the Cisco Catalyst Blade Switch 3032 offers, businesses can protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation.
To guard against denial-of-service (DoS) 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, and TCP and User Datagram Protocol (UDP) ports. ACL lookups are performed 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 the port is connected. Port security can also control the total number of devices plugged into a switch port, reducing the risk from unauthorized servers plugged into the blade enclosure.
Secure Shell (SSH) Protocol, Kerberos Protocol, and Simple Network Management Protocol Version 3 (SNMPv3) encrypt administrative and network management information, protecting the network from tampering and eavesdropping. TACACS+ and RADIUS authentication enable centralized access control of switches and restrict unauthorized users from altering the configurations. Alternatively, a local user name 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 capability 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 can provide location-based IP address assignment by providing both the switch and the port ID to a DHCP server. An Option 82-aware DHCP server such as the Cisco Network Registrar can use this information to assign the specific IP address to the requesting server.
The Private VLAN and Private VLAN Edge features isolate ports on a switch, helping ensure that traffic travels directly from the entry point to the aggregation device through a virtual path and cannot be directed to another port and thus helping isolate a server from other servers in the same blade enclosure.
The Cisco Catalyst Blade Switch 3032 offers several high-availability features to minimize network downtime, maintain mission-critical servers and applications, and reduce TCO.
Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus (PVST+), UplinkFast, and PortFast, maximize network uptime. PVST+ allows Layer 2 load sharing on redundant links to efficiently use the extra capacity inherent in a redundant design. UplinkFast and PortFast help reduce the standard 30- to 60-second Spanning Tree Protocol convergence time. Loop Guard and Bridge Protocol Data Unit (BPDU) Guard provide Spanning Tree Protocol loop avoidance.
The Cisco Catalyst Blade Switch 3032 uses redundant power and cooling capabilities of the Dell PowerEdge M1000e infrastructure to provide maximum availability to customers.
The Cisco Catalyst Blade Switch 3032 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 3032 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 traffic flows and enforce policies based on Layer 2 and 3 QoS fields.
To implement QoS, the Cisco Catalyst Blade Switch 3032 first identifies traffic flows or packet groups and classifies or reclassifies these groups using the differentiated services code point (DSCP) field or the IEEE 802.1p class-of-service (CoS) field. Classification can be based on criteria as specific as the source or destination IP address, source or destination MAC address, or Layer 4 TCP or UDP port. At ingress, the Cisco Catalyst Blade Switch 3032 will also police to determine whether a packet is in or out of profile; mark to change the classification label, pass-through, or dropout of profile packets; queue packets based on classification; and queue services 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 3032 supports four egress queues per port, which allows the network administrator to be discriminating and specific in assigning priorities for the 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 3032 supports Shaped Round Robin (SRR) and strict priority queuing. The SRR queuing algorithm helps ensure differential prioritization.
The Catalyst Blade Switch 3032 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 perform initial configuration and setup. Hence, users do not need any retraining.
The Cisco Catalyst Blade Switch 3032 provides extensive management capabilities 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 CiscoWorks 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.
Basic IP Routing
The Catalyst Blade Switch 3032 offers customers high-performance basic IP routing. It uses Cisco Express Forwarding (CEF/dCEF) hardware routing architecture to deliver basic IP unicast routing protocols that include static routing, Routing Information Protocol, and Cisco Enhanced Integrated Gateway Routing Protocol (EIGRP) Stub. The switch does not support Open Shortest Path First (OSPF) Protocol and Border Gateway Protocol (BGP).
