Cisco Catalyst Blade Switch 3120 for HP

The Cisco Catalyst® Blade Switch 3120 represents the next-generation networking solution for blade server environments. Built on the market-leading Cisco® hardware and Cisco IOS® Software, the Cisco Catalyst Blade Switch 3120 is engineered with unique technologies specifically designed to meet the rigors of blade server-based application infrastructure. Specifically, the switch is designed to deliver scaleable, high-performance, highly resilient connectivity while supporting ongoing IT initiatives to reduce server infrastructure complexity and total cost of ownership (TCO).

The Cisco Catalyst Blade Switch 3120 for HP has two configurations and SKUs. One configuration allows customers to connect the switch to the existing network fabric using Gigabit Ethernet uplinks, and the other configuration allows customers to connect the switch to the existing network fabric using Gigabit and 10 Gigabit Ethernet uplinks.

Configuration 1: Cisco Catalyst Blade Switch 3120G for HP
• Supports 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)

Configuration 2: Cisco Catalyst Blade Switch 3120X for HP
• Supports up to 4 10/100/1000BASE-T ports and 2 X2-based 10 Gigabit Ethernet ports

Virtual Blade Switch (VBS) Technology
With the Cisco Catalyst Blade Switch 3120, Cisco introduces a unique technology called the Virtual Blade Switch (VBS). This switch virtualization technology treats the interconnected physical switches within a rack as one logical switch. This innovation is the foundation of the switches' capability to deliver increased performance and resilience while simplifying operations and management.
The VBS delivers a number of specific advantages:
• By significantly simplifying data center design and operations, the VBS reduces infrastructure complexity, improves network resiliency, and increases the operational manageability of the blade-switching environment.
• By providing up to160 Gbps upstream, the VBS provides exceptional performance. In addition, the VBS can double the bandwidth available to a server.
• Because the VBS appears as a single node, both the Layer 2 and Layer 3 topologies are greatly simplified, increasing fabric stability and reducing convergence times after a topology change. The VBS offers several layers of link virtualization, which increases redundancy and available bandwidth.
• The VBS uses the same Cisco IOS Software interface, MIBs, and management tools as the rest of the Cisco Catalyst family, which simplifies operations and management, helping ensure consistent implementation and operation of end-to-end features such as quality of service (QoS).
• A number of VBS features reduce TCO. Link virtualization increases utilization and reduces potential port count. Similarly, the capability to mix-and-match 10 Gigabit Ethernet switches provides customers with a cost-effective migration path. In addition, the advanced operations and troubleshooting tools reduce operating expenses.

Cisco Catalyst Blade Switch 3120 Software
The Cisco Catalyst Blade Switch 3120 ships with the IP Base feature set. The IP Base feature set includes advanced QoS, a suite of security features, rate-limiting, access control lists (ACLs), and basic static and Routing Information Protocol (RIP) routing capability.
Customers can upgrade the software to either the IP Services or Advanced IP Services feature set. The IP Services feature set provides a richer set of enterprise-class features, including advanced hardware-based IP unicast and multicast routing: Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Protocol Independent Multicast (PIM), and so on. The Advanced IP Services feature set offers IPv6 routing.
Customers can transparently upgrade the software feature set through Cisco IOS Software activation. Software activation authorizes and enables the Cisco IOS Software feature sets. A special file contained in the switch, called a license file, is examined by the Cisco IOS Software when the switch is powered on. Cisco IOS Software activates the appropriate feature set based on the license type. License types can be changed, or upgraded, to activate a different feature set.


Features and Benefits

Ease of use and ease of deployment

The VBS is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS Software version running on the VBS to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the VBS.

Ease-of-use features include the following:

• Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment.
• Master configuration management helps ensure that all switches are automatically upgraded when the master switch receives a new software version. Automatic software version checking and updating help ensure that all switch members in the VBS have the same software version.
• Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.
• Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all
switch ports.
• Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel® groups or Gigabit EtherChannel groups to link to another switch, router, or server.
• Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP. The Cisco Catalyst Blade Switch 3120 now supports LACP channels to blade servers, thus doubling server bandwidth to the network.
• Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.

Availability and Scalability

Superior resiliency for higher server and application availability

• The VBS is highly resilient. Each switch can operate both as master controller and as forwarding processor. Each switch in the VBS can serve as a master, creating a 1:N availability scheme for network control. In the unlikely event of a single-unit failure, all other units continue to forward traffic and maintain operation.

High-availability features include the following:

• Cross-switch EtherChannel provides the capability to configure Cisco EtherChannel technology across different members of the VBS for high resiliency.
• IEEE 802.1D Spanning Tree Protocol support for redundant backbone connections and loop-free networks simplifies network configuration and improves fault tolerance.
• Cisco UplinkFast and BackboneFast technologies help ensure quick failover recovery, enhancing overall network stability and reliability.
• IEEE 802.1s/w Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) provide rapid spanning-tree convergence independent of spanning-tree timers and also offer the benefit of Layer 2 load balancing and distributed processing. The VBS units behave as a single spanning-tree node.
• Per-VLAN Rapid Spanning Tree (PVRST+) allows rapid spanning-tree reconvergence
on a per-VLAN spanning-tree basis, without requiring the implementation of spanning-tree instances.
• VLAN Trunking Protocol (VTP) pruning limits bandwidth consumption on VTP trunks by flooding broadcast traffic only on trunk links required to reach the destination devices.
• The trunk failover feature allows rapid failover to the redundant switch in the blade enclosure if all uplinks from the primary switch fail. When the uplinks fail, the switch shuts down the ports connected to the blade servers and lets network interface card (NIC) teaming software direct traffic to the redundant switch. This feature is also known as link-state tracking.
• Switch port autorecovery (Errdisable) automatically attempts to re-enable a link that is disabled because of a network error.
• Power and cooling resiliency are provided through redundant power and cooling capabilities from the blade enclosure.
• Flexlink provides link redundancy with convergence time of less than 100 milliseconds (ms).
• Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, fail-safe routing topologies.
• Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused by incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.
• Switch-port autorecovery (Errdisable) automatically attempts to reactivate a link that is disabled because of a network error.
• Per-port broadcast, multicast, and unicast storm control prevents faulty servers from degrading overall system performance.
• Internet Group Management Protocol (IGMP) snooping provides fast client joins and leaves of multicast streams and limits bandwidth-intensive video traffic to only the requestors.
• Multicast VLAN registration (MVR) continuously sends multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security reasons.


Advanced QoS

The VBS offers industry-leading mechanisms for marking, classification, and scheduling to deliver superior performance for data, voice, and video traffic, all at wire speed.

Following are some of the QoS features supported:

• Wire-rate performance supports highly granular QoS functions (for example, granular rate limiting).
• Cross-switch QoS allows QoS to be configured across the entire VBS.
• IEEE 802.1p class of service (CoS) and differentiated services code point (DSCP) field classification is provided, using marking and reclassification on a per-packet basis by source and destination IP address, MAC address, or Layer 4 TCP or User Datagram Protocol (UDP) port number.
• Cisco control plane and data plane QoS access control lists (ACLs) on all ports help ensure proper marking on a per-packet basis.
• Four egress queues per port help enable differentiated management of up to four traffic types.
• Shaped Round Robin (SRR) scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress queues and egress queues.
• Weighted Tail Drop (WTD) provides congestion avoidance at the ingress and egress queues before a disruption occurs.
• Strict priority queuing helps ensure that the highest-priority packets are serviced ahead of all other traffic.
• The committed information rate (CIR) function provides bandwidth in increments as low as 8 Kbps.
• Rate limiting is provided based on source and destination IP address, source and destination MAC address, Layer 4 TCP and UDP information, or any combination of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy maps.
• Up to 64 aggregate or individual policers are available.


Networkwide security features

The VBS supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with IEEE 802.1x and extensions. This set of comprehensive features not only helps prevent external attacks, but defends the network against "man-in-the-middle" attacks, a primary concern in today's business environment. The switch also supports the Network Admission Control (NAC) security framework.

Security features include the following:

• Dynamic Address Resolution Protocol (ARP) Inspection (DAI) helps ensure user integrity by preventing malicious users from exploiting the insecure nature of the ARP protocol.
• DHCP snooping prevents malicious users from spoofing a DHCP server and sending out bogus addresses. This feature is used by other primary security features to prevent a number of other attacks such as ARP poisoning.
• IP source guard prevents a malicious user from spoofing or taking over another user's
IP address by creating a binding table between the client's IP and MAC address, port,
and VLAN.
• Private VLANs restrict traffic between hosts in a common segment by segregating traffic at Layer 2, turning a broadcast segment into a nonbroadcast multi-access-like segment.
• Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic.
• The nicast Reverse Path Forwarding (RPF) feature helps mitigate problems caused by the introduction of malformed or forged (spoofed) IP source addresses into a network by discarding IP packets that lack a verifiable IP source address.
• IEEE 802.1x enables dynamic, port-based security, providing user authentication.
• IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless of where the user is connected.
• IEEE 802.1x and port security are provided to authenticate the port and manage network access for all MAC addresses, including that of the client.
• IEEE 802.1x with an ACL assignment enables the user of specific identity-based security policies regardless of where the user is connected.
• IEEE 802.1x with guest VLAN allows guests without IEEE 802.1x clients to have limited network access on the guest VLAN.
• Web authentication for non-IEEE 802.1x clients allows non-IEEE 802.1x clients to use a Secure Sockets Layer (SSL) based browser for authentication.
• Cisco security VLAN ACLs on all VLANs prevent unauthorized data flows from being bridged within VLANs.
• Cisco standard and extended IP security router ACLs define security policies on routed interfaces for control plane and data plane traffic. IPv6 ACLs can be applied to filter
IPv6 traffic.
• Port-based ACLs for Layer 2 interfaces allow security policies to be applied on individual switch ports.
• Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSH, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions.
• Bidirectional data support on the Switched Port Analyzer (SPAN) port allows the Cisco Intrusion Detection System (IDS) to take action when an intruder is detected.
• TACACS+ and RADIUS authentication facilitates centralized control of the switch and restricts unauthorized users from altering the configuration.
• MAC address notification allows administrators to be notified of users added to or removed from the network.
• Port security secures the access to an access or trunk port based on the MAC address.
• Multilevel security on console access prevents unauthorized users from altering the switch configuration.
• Bridge protocol data unit (BPDU) guard shuts down Spanning Tree PortFast-enabled interfaces when BPDUs are received to avoid accidental topology loops.
• Spanning Tree Root Guard (STRG) prevents edge devices not in the network administrator's control from becoming Spanning Tree Protocol root nodes.
• IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.
• Dynamic VLAN assignment is supported through implementation of VLAN membership policy server client capability to provide flexibility in assigning ports to VLANs. Dynamic VLAN facilitates the fast assignment of IP addresses.
