System

System identifier

The ONS 15310-MA SDH system identifier is set to its IEEE 802.3

 

 

MAC address.

 

 

 

SEL

Selector

The selector field directs the protocol data units (PDUs) to the correct

 

 

destination using the CLNP network layer service. Selector values

 

 

supported by the ONS 15310-MA SDH include:

 

 

00—Network Entity Title (NET). Used to exchange PDUs in the

 

 

ES-IS and IS-IS routing exchange protocols. (See the

 

 

“8.6.4.1 End System-to-Intermediate System Protocol” section

 

 

on page 8-28, and the “8.6.4.2 Intermediate

 

 

System-to-Intermediate System Protocol” section on page 8-28.)

 

 

1D—Selector for Transport Class 4 (and for FTAM and TL1

 

 

applications

 

 

AF—Selector for the TARP protocol

 

 

2F—Selector for the GRE IP-over-CLNS tunnel (ITU/RFC

 

 

standard)

 

 

CC—Selector for the Cisco IP-over-CLNS tunnels (Cisco

 

 

specific)

 

 

E0—Selector for the OSI ping application (Cisco specific)

 

 

NSELs are only advertised when the node is configured as an ES.

 

 

They are not advertised when a node is configured as an IS. Tunnel

 

 

NSELs are not advertised until a tunnel is created.

 

 

 

Figure 8-15shows the default ISO-DCC NSAP address delivered with the ONS 15310-MA SDH. The System ID is automatically populated with the node’s MAC address.

The ONS 15310-MA SDH main NSAP address is shown on the node view Provisioning > OSI > Main Setup subtab. This address is also the Router 1 primary manual area address, which is viewed and edited on the Provisioning > OSI > Routers subtab. See the “8.6.6 OSI Virtual Routers” section on page 8-32for information about the OSI router and manual area addresses in CTC.

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.
