Monitoring (RMON), Simple Network Management Protocol (SNMP), and syslog protocols.
Network management tools such as CiscoWorks LAN Management Solution (LMS) and
Cisco Network Assistant software, PC-based tools for quick configuration based on preset
templates are available. Another ease of use feature is Cisco Smartports macros to
generate and reduce time to setup and administer Cisco IOS Software configurations.
The following new features are available with Cisco IOS Software Release 12.2(40)EX for
enterprise Ethernet switches:
●
Configuration Replace: The configuration replacement and configuration rollback feature
provides the capability to replace the current running configuration with any saved Cisco
IOS Software 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.
●
Multicast VRF-Lite: VRF-Lite allows the customer to configure multiple private routing
domains for network virtualization and VPNs. Multicast support has now been added to
VRF-Lite, allowing multicast traffic per VRF.
●
Source Specific Multicast: 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 IGMPv3.
●
IP Service-level Agreements (IP SLAs) support: Cisco IOS Software 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 Software 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 Software IP SLAs use active monitoring to generate traffic in
a continuous, reliable, and predictable manner, thus facilitating the measurement of
network performance and health.
●
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.
●
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: ARP, ping, traceroute, SNMP,
syslog, HSRP, IP SLAs, Trivial File Transfer Protocol (TFTP), FTP, and Unicast Reverse
Path Forwarding (uRPF).
●
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).
●
EIGRP for 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.
●
Auto-QoS voice-over-IP (VoIP) enhancement: Auto-QoS can now be used transparently
when voice over IP is utilized in the network. This is an enhancement to the Auto-QoS
