Chapter 1 Overview of the ML-Series Card

Key ML-Series Features

Link Aggregation (FEC and POS)

The ML-Series offers Fast EtherChannel and POS channel link aggregation. Link aggregation groups multiple ports into a larger logical port and provides resiliency during the failure of any individual ports. The ML-Series supports a maximum of four Ethernet ports in Fast EtherChannel, and two SONET virtual ports in POS channel. POS channel is only supported with LEX encapsulation.

Traffic flows map to individual ports based on MAC source address (SA)/destination address (DA) for bridged packets and IP SA/DA for routed packets. There is no support for policing or class-based packet priorities when link aggregation is configured.

RMON

The ML-Series card features RMON that allows network operators to monitor the health of the network with an NMS. ONG RMON is recommended for the ML-100T-8. The ONG RMON contains the statistics, history, alarms, and events MIB groups from the standard RMON MIB. The standard Cisco IOS RMON is also available. A user can access RMON threshold provisioning through TL1 or CTC. For more information on RMON, refer to the “SNMP Remote Monitoring” section in “SNMP” chapter of the Cisco ONS 15310-CL and Cisco ONS 15310-MA Reference Manual.

RPR

RPR is an emerging network architecture designed for metro fiber ring networks. This new MAC protocol is designed to overcome the limitations of STP, RSTP, and SONET in packet-based networks. RPR convergence times are comparable to SONET and much faster than STP or RSTP. RPR operates at the Layer 2 level and is compatible with Ethernet and protected or unprotected SONET circuits.

SNMP

The Cisco ONS 15310-CL, the Cisco ONS 15310-MA, and the ML-Series cards have SNMP agents and support SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c) sets and traps. The Cisco ONS 15310-CL and the Cisco ONS 15310-MA accept, validate, and forward get/getNext/set requests to the ML-Series through a proxy agent. Responses from the ML-Series are relayed by the Cisco ONS 15310-CL and the Cisco ONS 15310-MA to the requesting SNMP agents.

The ML-Series card SNMP support includes:

•STP traps from Bridge-MIB (RFC 1493)

•Authentication traps from RFC 1157

•Export of QoS statistics through the CISCO-PORT-QOS-MIB extension

For more information on how the ONS 15310-CL implements SNMP, refer to the “SNMP” chapter of the Cisco ONS 15310-CL and Cisco ONS 15310-MA Reference Manual. For more information on specific MIBs, refer to the Cisco SNMP Object Navigator at http://www.cisco.com.

15310-CL, 15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
