New and Changed Information interfaces. Prior to this release, IP addresses for LAN interfaces were obtained using BOOTP during the AutoInstall process. The AutoInstall Using DHCP for LAN Interfaces feature also enables the routing device to recognize IP address allocation messages coming from regular BOOTP servers, providing a seamless transition for those devices already using BOOTP servers for AutoInstall. Additionally, this feature enables uploading of configuration files using unicast TFTP.
New and Changed Information Class-Based Ethernet CoS Matching & Marking Platforms: Cisco 7200 series and Cisco 7500 series routers The Class-Based Ethernet Class of Service (CoS) Matching & Marking extends IOS capabilities to match packets by looking at the CoS value of the packet and mark packets with user defined CoS values. This feature can be used for L2 CoS to L3 TOS mapping. CoS Matching & Marking can be configured via the IOS QoS Mod CLI framework.
New and Changed Information probabilities to those packets. This feature adds two new commands, random-detect dscp and dscp. It also adds two new arguments, dscp-based and prec-based, to two existing WRED-related commands—the random-detect (interface) command and the random-detect-group command.
New and Changed Information Distributed Traffic Shaping Platforms: Cisco 7500 series routers The DTS feature is one element used to manage the bandwidth of an interface to avoid congestion, to meet remote site requirements, and to conform to a service rate that is provided on that interface. DTS uses queues to buffer traffic surges that can congest a network. Data is buffered and then sent into the network at a regulated rate.
New and Changed Information Frame Relay Fragmentation with Hardware Compression Platforms: Cisco 7200 series routers The Frame Relay Fragmentation with Hardware Compression feature introduces the following functionality: Frame Relay Fragmentation and Hardware Compression Interoperability This new feature enables FRF.12, FRF.
New and Changed Information In deployment cases where IGMP v3 cannot be used (for example, if it is not supported by the receiver host or its applications), there are two other mechanisms to enable Source Specific Multicast (SSM): URL Rendezvous Directory (URD) and IGMP v3 lite. Both of these features were introduced with SSM in Cisco IOS Release 12.1(5)T.
New and Changed Information IP DSCP Marking for Frame-Relay PVC Platforms: Cisco 7100 series, Cisco 7200 series, and Cisco 7500 series routers The functionality of configuring a policy on a main or a subinterface to match and set IP type of service (ToS) and differentiated services code point (DSCP) bits has existed in Cisco IOS Release 12.0S and Cisco IOS Release 12.0(7)XE. This feature was introduced to Cisco IOS 12.1(2)T with the added support of configuring a policy on an ATM PVC.

IEEE 802.1Q encapsulation enables you to interconnect a VLAN capable router with another VLAN capable device.
New and Changed Information The RSVP support for Frame Relay feature allows RSVP to work with per VC (data link connection identifier (DLCI)) queueing for voice-like flows. Traffic shaping must be enabled in a Frame Relay environment for accurate admission control of resources (bandwidth and queues) at the congestion point; that is, the VC itself. Specifically, RSVP can work with VCs defined at the interface and subinterface levels.
New and Changed Information TN3270 Server Connectivity Enhancements Platforms: Cisco 7200 series and Cisco 7500 series routers The TN3270 Server Connectivity Enhancements feature, an enhancement to the existing TN3270 Server feature, provides the following new functions: • Dynamic LU naming • Inverse DNS nailing • TN3270 Server security enhancements Traceroute Enhancement for MPLS Platforms: Cisco 7200 series and Cisco 7500 series routers The traceroute enhancements for MPLS feature introduces two ne
New and Changed Information Turbo Access Control Lists Platforms: Cisco 7200 series routers Access control lists (ACLs) are normally searched sequentially to find a matching rule, and ACLs are ordered specifically to take this factor into account. Because of the increasing needs and requirements for security filtering and packet classification, ACLs can expand to the point that searching the ACL adds a significant amount of time and memory when packets are being forwarded.
New and Changed Information VPN Accelerator Card Enhancements Platforms: Cisco 7100 series and Cisco 7200 series routers The VPN Accelerator Card Enhancements feature displays the packet statistics of the VPN accelerator card and controller. It is available on the Cisco 7100 series router with the ISA and the ISM. It is available on the Cisco 7200 series router only if an ISA is installed.

This feature supports the following IEEE 802.
New and Changed Information row is created successfully, the cciStatus is active(1). When creating a new row, set the cciDescr object along with the cciStatus in a single snmp set pdu command. If the row is already active, only the cciDescr object can be modified. The other option is to delete the row first by setting the cciStatus to destroy(6), and then recreate the row with a new value for cciDescr. When creating a new row, the ifIndex is validated first.
New and Changed Information Event MIB Platforms: Cisco 7200 series and Cisco 7500 series routers The Event MIB is an asynchronous notification mechanism standardized for use by network management systems using Simple Network Management Protocol (SNMP). The Event MIB provides the ability to monitor the Cisco Management Information Base (MIB) objects on the local or remote system using SNMP and take simple action whenever a trigger condition is met.
New and Changed Information General Packet Radio Service Release 1.4 Platforms: Cisco 7200 series routers Note General Packet Radio Service (GPRS) Release 1.4 is a specially licensed feature that is available only through a controlled image release in Cisco IOS Release 12.1(3)T. GPRS Release 1.4 is the recommended upgrade for both GPRS Release 1.2 (available in Cisco IOS Release 12.1(1)GA) and GPRS Release 1.3 (available in Cisco IOS Release 12.1(2)GB).
New and Changed Information HSRP Support for MPLS VPNs Platforms: Cisco 7200 series and Cisco 7500 series routers The HSRP support for Multiprotocol Label Switching (MPLS) VPNs feature enables ICMP redirection on interfaces configured with the Hot Standby Router Protocol (HSRP). The Internet Control Message Protocol (ICMP) is a network layer Internet protocol that provides message packets to report errors and other information relevant to IP processing.
New and Changed Information • Determines the routes for traffic flows across a network based on the resources the traffic flow requires and the resources available in the network • Employs “constraint-based routing,” in which the path for a traffic flow is the shortest path that meets the resource requirements (constraints) of the traffic flow • Recovers from link or node failures by adapting to the new constraints presented by the changed topology • Transports packets using MPLS forwarding crossing
New and Changed Information • SVCs with ingress and egress (AAL5) common part convergence sublayer (CPCS) service data unit (SDU) maximum size of at least 1506 bytes when supporting LLC/SNAP encapsulation, and 1502 bytes when supporting virtual circuit multiplexed encapsulation. • Maximum Transmission Unit (MTU) negotiation as described in RFC-1626, “Default IP MTU size for use over ATM AAL5”.
New and Changed Information RSVP provides admission control. However, to provide the bandwidth and delay guarantees for voice traffic and get admission control, RSVP must work with LLQ. The RSVP support for LLQ feature allows RSVP to classify voice flows and queue them into the priority queue within the LLQ system while simultaneously providing reservations for nonvoice flows by getting a reserved queue.
New and Changed Information Transparent Common Channel Signaling Platforms: Cisco 7200 series and Cisco 7500 series routers Transparent CCS allows the connection of two PBXs with digital interfaces that use a proprietary or unsupported CCS protocol without the need for interpretation of CCS signaling for call processing. T1/E1 traffic is transported transparently through the data network and the feature preserves proprietary signaling.
New and Changed Information New Hardware Features in Release 12.1(3)T The following new hardware features are supported by the Cisco 7000 family for Cisco IOS Release 12.
New and Changed Information Bidirectional PIM Platforms: Cisco 7200 series and Cisco 7500 series routers Bidirectional PIM (bidir-PIM) is a variant of the Protocol Independent Multicast (PIM) suite of routing protocols for IP multicast. Bidir-PIM is derived from the mechanisms of Protocol Independent Multicast sparse mode (PIM SM) and shares many of its protocol elements. In short, bidir-PIM is PIM SM with shared tree, but no shortest path tree operations.
New and Changed Information Frame Relay Switching Enhancements Platforms: Cisco 7200 series and Cisco 7500 series routers The Frame Relay Switching Enhancements feature enables a router in a Frame Relay network to be used as a Frame Relay switch. This feature provides the following functionality: Traffic Shaping on Switched PVCs You can now configure Frame Relay traffic shaping on switched permanent virtual connections (PVCs).
New and Changed Information H.323 Support for Virtual Interfaces Platforms: Cisco 7200 series routers With the H.323 Support for Virtual Interfaces feature, you can configure the IP address of the gateway, so that the IP address included in the H.323 packet is deterministic and consistently indicates the same address for the source. In previous releases of the Cisco IOS software, the source address included in the H.323 packet could vary depending on the protocol (RAS, H.225, H.245, or RTP).
New and Changed Information OSPF Flooding Reduction Platforms: Cisco 7100 series, Cisco 7200 series, and Cisco 7500 series routers The explosive growth of the Internet has placed the focus on the scalability of Interior Gateway Protocols such as Open Shortest Path First (OSPF). The networks using OSPF are becoming larger every day and will continue to expand to accommodate the demand to connect to the Internet.
