Chapter 7 Circuits and Tunnels

Bridge and Roll

Manual—You must complete a manual roll after a valid signal is received. One-way destination rolls are always manual.

Roll Path—The fixed point of the roll object.

Roll From Path— The old path that is being rerouted.

Roll To Path—The new path where the Roll From Path is rerouted.

Complete—Completes a manual roll after a valid signal is received. You can complete a manual roll if it is in a ROLL_PENDING status and you have not yet completed the roll or have not cancelled its sibling roll.

Force Valid Signal—Forces a roll onto the Roll To Circuit destination without a valid signal. If you choose Force Valid Signal, traffic on the circuit that is involved in the roll will be dropped when the roll is completed.

Finish—Completes the circuit processing of both manual and automatic rolls and changes the circuit status from ROLL_PENDING to DISCOVERED. After a roll, the Finish button also removes any cross-connects that are no longer used from the Roll From Circuit field.

Cancel—Cancels the roll process. When the roll mode is Manual, cancel roll is only allowed before you click the Complete button. When the roll mode is Auto, cancel roll is only allowed before a good signal is detected by the node or before you click the Force Valid Signal button.

7.9.2Roll Status

Table 7-10lists the roll statuses. You can only reroute circuits that have a DISCOVERED status. (See Table 7-1 on page 7-3for a list of circuit statuses.) You cannot reroute circuits that are in the ROLL_PENDING status.

Table 7-10

Roll Statuses

 

 

 

State

 

Description

 

 

ROLL_PENDING

The roll is awaiting completion or cancellation.

 

 

ROLL_COMPLETED

The roll is complete. Click the Finish button.

 

 

ROLL_CANCELLED

The roll has been canceled.

 

 

 

TL1_ROLL

 

A TL1 roll was initiated.

 

 

Note If a roll is created using TL1, a CTC user cannot complete or

 

 

cancel the roll. Also, if a roll is created using CTC, a TL1 user

 

 

cannot complete or cancel the roll. You must use the same

 

 

interface to complete or change a roll.

 

 

 

INCOMPLETE

 

This state appears when the underlying circuit becomes incomplete. To

 

 

correct this state, you must fix the underlying circuit problem before the

 

 

roll state will change.

 

 

For example, a circuit traveling on Nodes A, B, and C can become

 

 

INCOMPLETE if Node B is rebooted. The cross connect information is

 

 

lost on Node B during a reboot. The Roll State on Nodes A and C will

 

 

change to INCOMPLETE.

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.
