SNMP Trap Content

12.6 SNMP Trap Content

The ONS 15310-MA SDH use SNMP traps to generate all alarms and events, such as raises and clears. The traps contain the following information:

Object IDs that uniquely identify each event with information about the generating entity such as the slot or port, synchronous transport signal (VC high-order path), and Virtual Tributary (VC low-order path).

Severity of the alarm (critical, major, minor, or event) and service effect (service-affecting or non-service-affecting).

Date and time stamp when the alarm occurred.

12.6.1Generic and IETF Traps

The ONS 15310-MA SDH support the generic and IETF traps listed in Table 12-4.

Description

 

 

 

 

coldStart

 

RFC1907-MIB

Agent up, cold start.

 

 

 

 

warmStart

 

RFC1907-MIB

Agent up, warm start.

 

 

 

authenticationFailure

RFC1907-MIB

Community string does not match.

 

 

 

 

newRoot

 

RFC1493/

Sending agent is the new root of the spanning tree.

 

 

BRIDGE-MIB

 

 

 

 

topologyChange

RFC1493/

A port in a bridge has changed from Learning to

 

 

BRIDGE-MIB

Forwarding or Forwarding to Blocking.

 

 

 

entConfigChange

RFC2737/

The entLastChangeTime value has changed.

 

 

ENTITY-MIB

 

 

 

 

dsx1LineStatusChange

RFC2495/

A dsx1LineStatusChange trap is sent when the value of

 

 

E1-MIB

an instance of dsx1LineStatus changes. The trap can be

 

 

 

used by an NMS to trigger polls. When the line status

 

 

 

change results from a higher-level line status change (for

 

 

 

example, a DS3), no traps for the E1 are sent.

 

 

 

dsx3LineStatusChange

RFC2496/

A dsx3LineStatusLastChange trap is sent when the value

 

 

DS3-MIB

of an instance of dsx3LineStatus changes. This trap can

 

 

 

be used by an NMS to trigger polls. When the line status

 

 

 

change results in a lower-level line status change (for

 

 

 

example, a E1), no traps for the lower-level are sent.

 

 

 

 

risingAlarm

 

RFC2819/

The SNMP trap that is generated when an alarm entry

 

 

RMON-MIB

crosses the rising threshold and the entry generates an

 

 

 

event that is configured for sending SNMP traps.

 

 

 

 

fallingAlarm

 

RFC2819/

The SNMP trap that is generated when an alarm entry

 

 

RMON-MIB

crosses the falling threshold and the entry generates an

 

 

 

event that is configured for sending SNMP traps.

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.
