- Superior resiliency for higher server / application availability
The Virtual Blade Switch (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:
Cross-switch EtherChannel provides the ability 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 to 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 Virtual Blade Switch 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 less than 100 ms.
Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, failsafe 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 systems 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 Virtual Blade Switch (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 for highly granular QoS functions (for example, granular rate limiting).
Cross-switch QoS allows QoS to be configured across the entire VBS
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/UDP port number.
Cisco control-plane and data-plane QoS 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 Cisco 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/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.
- Network wide security features
The Catalyst Blade Switch 3130 supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with 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:
Dynamic 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.
Unicast 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 allows 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 allows for specific identity-based security policies regardless of where the user is connected.
IEEE 802.1x with guest VLAN allows guests without 802.1x clients to have limited network access on the guest VLAN.
Web authentication for non-802.1x clients allows non-802.1x clients to use an SSL-based browser for authentication.
Cisco security VLAN ACLs on all VLANs prevents 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 Protocol, 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 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 MAC address.
Multilevel security on console access prevents unauthorize
