ASAP Ethernet Statistics Parameters (continued)

 

 

 

Parameter

 

Meaning

 

 

dot3StatsInternalMacTransmitErrors

A count of frames for which transmission on a particular

 

 

interface fails due to an internal MAC sublayer transmit error.

 

 

A frame is only counted by an instance of this object if it is not

 

 

counted by the corresponding instance of the

 

 

dot3StatsLateCollisions object, the

 

 

dot3StatsExcessiveCollisions object, or the

 

 

dot3StatsCarrierSenseErrors object.

 

 

dot3StatsFrameTooLongs

A count of frames received on a particular interface that exceed

 

 

the maximum permitted frame size.

 

 

dot3StatsInternalMacReceiveErrors

A count of frames for which reception on a particular interface

 

 

fails due to an internal MAC sublayer receive error. A frame is

 

 

only counted by an instance of this object if it is not counted by

 

 

the corresponding instance of the dot3StatsFrameTooLongs

 

 

object, the dot3StatsAlignmentErrors object, or the

 

 

dot3StatsFCSErrors object. The precise meaning of the count

 

 

represented by an instance of this object is

 

 

implementation-specific. In particular, an instance of this

 

 

object may represent a count of receive errors on a particular

 

 

interface that are not otherwise counted.

 

 

dot3StatsSymbolErrors

A count of frames for which transmission on a particular

 

 

interface fails due to an internal MAC sublayer transmit error.

 

 

A frame is only counted by an instance of this object if it is not

 

 

counted by the corresponding instance of either the

 

 

dot3StatsLateCollisions object, the

 

 

dot3StatsExcessiveCollisions object, or the

 

 

dot3StatsCarrierSenseErrors object. The precise meaning of the

 

 

count represented by an instance of this object is

 

 

implementation-specific. In particular, an instance of this

 

 

object might represent a count of transmission errors on a

 

 

particular interface that are not otherwise counted.

 

 

 

12.6.2.2 ASAP Card Ether Ports Utilization Window

The Ether Ports Utilization window shows the percentage of Tx and Rx line bandwidth used by the Ethernet ports during consecutive time segments. The Utilization window provides an Interval menu that enables you to set time intervals of 1 minute, 15 minutes, 1 hour, and 1 day. Line utilization is calculated with the following formulas:

Rx = (inOctets + inPkts * 20) * 8 / 100% interval * maxBaseRate

Tx = (outOctets + outPkts * 20) * 8 / 100% interval * maxBaseRate

The interval is defined in seconds. The maxBaseRate is defined by raw bits per second in one direction for the Ethernet port (that is,1 Gbps). Table 12-7provides the maxBaseRate for ASAP Ethernet cards.

ONS 15600 specifications

Cisco Systems ONS 15600 is a highly versatile optical networking platform designed to meet the demands of modern telecommunications and data services. This multiservice edge platform supports various transmission mediums and offers a wide array of features that enable efficient data transport. Ideal for service providers and large enterprises, the ONS 15600 is engineered to provide scalable and reliable optical transport solutions.

One of the notable features of the ONS 15600 is its capability to support multiple protocols, including SONET/SDH, Ethernet, OTN, and legacy TDM services. This flexibility allows users to tailor their networks according to specific service requirements while ensuring interoperability with existing infrastructure. The platform is designed to facilitate seamless service migration, accommodating both legacy and next-generation services.

The modular architecture of the ONS 15600 enhances its scalability. It allows for easy expansion by incorporating additional line cards or interface modules without requiring significant downtime. This modularity ensures that service providers can evolve their networks over time, responding to increasing bandwidth demands and new service offerings with ease.

Incorporating advanced technologies, the ONS 15600 employs Dense Wavelength Division Multiplexing (DWDM), significantly increasing the capacity of fiber networks by allowing multiple signals to be transmitted simultaneously over a single optical fiber. This capability helps to optimize fiber utilization and reduce operational costs. In addition, the platform supports Optical Transport Network (OTN) for improved error detection and correction, contributing to higher reliability and performance.

Another key characteristic of the ONS 15600 is its robust management capabilities. The platform can be managed through Cisco's Optical Networking Manager (ONM), providing a centralized interface for network configuration, monitoring, and troubleshooting. This enhances operational efficiency and minimizes downtime, allowing service providers to focus on delivering quality services to their customers.

The ONS 15600 also prioritizes security, offering various features like encryption and access control to safeguard sensitive data during transmission. With its combination of scalability, flexibility, and security, the Cisco ONS 15600 stands out as a reliable choice for organizations looking to enhance their optical networking capabilities while meeting the evolving demands of the digital landscape. Its commitment to quality and performance makes it a cornerstone of modern optical networks.
