Cisco® announces Cisco IOS® Software updates for Cisco Catalyst® 3750-E, 3750, 3560-E, 3560, 2960, 3550, and 2970 Series Switches; and Cisco Catalyst Blade Switch 3000 Series. This release furthers Cisco leadership by providing integrated services for IPv6, secure voice, multicast, and manageability for enterprise deployments.
• IP Service-Level Agreements (IP SLAs) Support: Cisco IOS IP SLAs help enable customers to assure new business-critical IP applications, as well as IP services that utilize data, voice, and video. With Cisco IOS IP SLAs, users can verify service guarantees, increase network reliability by validating network performance, proactively identify network issues, and increase return on investment (ROI) by easing the deployment of new IP services. Cisco IOS IP SLAs use active monitoring to generate traffic in a continuous, reliable, and predictable manner, thus facilitating the measurement of network performance and health.
• Source-Specific Multicast (SSM): The SSM capability is an efficient and optimized multicast protocol that is used for one-to-many multicast applications such as video. The protocol is easier to deploy than traditional multicast protocols and utilizes Internet Group Management Protocol version 3 (IGMPv3).
• IP SLAs Enhanced Object Tracking: IP SLAs Enhanced Object Tracking support will allow switches utilizing HSRP to track IP SLA measurements and trigger hot standby failover based upon jitter, packet loss, or latency.
• Multicast Virtual Routing and Forwarding (VRF) Lite: VRF Lite allows the customer to configure multiple private routing domains for network virtualization and virtual private networks. Multicast support has now been added to VRF Lite allowing multicast traffic per VRF.
• Internet Group Management Protocol (IGMP) Proxy: This capability allows the switch to forward a host's request to join a multicast stream to a specific IP destination address.
• VRF-Aware IP Services: Various IP Services can now obtain information per VRF and are now VRF aware. The following services are now VRF aware: Address Resolution Protocol (ARP), ping, traceroute, Simple Network Management Protocol (SNMP), syslog, HSRP, IP SLAs, TFTP, FTP, and Unicast Reverse Path Forwarding (uRPF).
• Configuration Replace: The configuration replacement and configuration rollback feature provides the capability to replace the current running configuration with any saved Cisco IOS configuration file. This functionality can be used to revert to a previous configuration state, effectively rolling back any configuration changes that were made since that configuration file was saved. This feature simplifies and reduces operational overhead.
• Link Layer Discovery Protocol Media Extensions (LLDP-MED) Location Support: LLDP support has been extended to include client location information using the LLDP Media Extensions. The device location information can be used by inventory management for emergency response services, such as Enhanced 911 (E911).
• Enhanced Interior Gateway Routing Protocol (EIGRP) for Internet Protocol Version 6 (IPv6): The ability to route IPv6 prefixes is now available using EIGRP. EIGRP IPv6 utilizes IPv6 transport and communicates with IPv6 peers and advertises IPv6 routes.
• IPv6 Host Support for the Catalyst 2960: IPv6 host provides basic IPv6 management support for the Catalyst 2960 Switch. IPv6 host includes the following capabilities: IPv4/IPv6 dual stack, unicast address types, ICMPv6, AAAA DNS lookup over IPv4, Secure Shell (SSH) Protocol for v6, IPv6 neighbor discovery, CDP, Telnet, TFTP, traceroute for v6. Also available in the release is IPv6 express setup to ease deployment.
• IPv6 Multicast Listener Discovery (MLD) Snooping for the Catalyst 2960: When a host in an IPv6 network needs to receive a multicast stream, the MLD protocol is utilized. MLD snooping for the Catalyst 2960 Switch enables efficient distribution of IPv6 multicast data to clients attached to a switched network.
• Auto-Quality of Service (QOS) Voice Over IP (VoIP) Enhancement: Auto-QOS can now be used seamlessly when voice over IP is utilized in the network. This is an enhancement to the Auto-QOS functionality and adds support for port-based trust of DSCP and strict priority queuing for egress traffic.
• Cisco Media Access Control (MAC) Notification MIB: The MAC Notification MIB enables the switch to track MAC addresses that are learned or removed. Histories of the MAC addresses that are learned and deleted from the switch are tracked, and notifications can be generated based on threshold limits.
• Power over Ethernet (POE) Policing MIB: Cisco intelligent power management capabilities include enhanced power negotiation, power reservation, and per port power policing. POE policing allows notification and policing of a device that draws more inline power than what it had negotiated. The SNMP support for the POE policing feature allows network management to monitor the usage of POE on the switch and verify the operation of POE.
• Dynamic Voice Virtual LAN (VLAN) for MDA: This feature is an extension to the Multidomain Authentication (MDA) capability previously released. MDA now supports dynamic voice VLAN with Remote Authentication Dial In User Service (RADIUS).
