ASAP Card POS Ports Parameters (continued)

 

 

 

Parameter

 

Meaning

 

 

 

Tx Octets

 

Number of bytes transmitted (to the SONET/SDH path) after the

 

 

bytes undergoing HLDC encapsulation by the policy engine.

 

 

 

Rx Shorts

 

Number of packets below the minimum packet size received.

 

 

 

Rx Runts

 

Total number of frames received that are less than 5 bytes.

 

 

 

Rx Longs

 

Number of received frames that exceed the maximum transfer

 

 

unit (MTU).

 

 

Rx CRC Errors/HDLC Errors

HDLC errors received from SONET/SDH.

 

 

Rx Single Bit Errors

Number of received frames with single bit errors.

 

 

Rx Multi Bit Errors

Number of received frames with multibit errors.

 

 

Rx Type Invalid

Number of received frames with invalid type.

 

 

Rx Input Abort Packets

Number of received packets aborted before input.

 

 

Rx Input Drop Packets

Number of received packets dropped before input.

 

 

 

12.6.2.5 ASAP Card POS Ports Utilization Window

The POS Ports Utilization window shows the percentage of Tx and Rx line bandwidth used by the POS 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 * 8) / interval * maxBaseRate

Tx = (outOctets * 8) / 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). The maxBaseRate for ASAP cards is shown in Table 12-7 on page 12-16.

Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.

12.6.2.6 ASAP Card POS Ports History Window

The Ethernet POS Ports History window lists past Ethernet POS Ports statistics for the previous time intervals. The History window displays the statistics for each port for the number of previous time intervals as shown in Table 12-8. The listed parameters are defined in Table 12-9 on page 12-16.

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.
