12.6.2 ASAP Card Ethernet Performance Monitoring Parameters

Table 12-6

ASAP Ethernet Statistics Parameters (continued)

 

 

 

Parameter

 

Meaning

 

 

etherStatsBroadcastPkts

The total number of good packets received that were directed to

 

 

the broadcast address. Note that this does not include multicast

 

 

packets.

 

 

etherStatsMulticastPkts

The total number of good packets received that were directed to

 

 

a multicast address. Note that this number does not include

 

 

packets directed to the broadcast address.

 

 

etherStatsFragments

The total number of packets received that were less than

 

 

64 bytes in length (excluding framing bits but including FCS

 

 

bytes) and had either a bad FCS with an integral number of

 

 

bytes (FCS error) or a bad FCS with a nonintegral number of

 

 

bytes (alignment error).

 

 

Note It is entirely normal for etherStatsFragments to

 

 

increment. This is because it counts both runts (which

 

 

are normal occurrences due to collisions) and noise hits.

 

 

etherStatsPkts64Octets

The total number of packets (including bad packets) received

 

 

that were 64 bytes in length (excluding framing bits but

 

 

including FCS bytes).

 

 

etherStatsPkts65to127Octets

The total number of packets (including bad packets) received

 

 

that were between 65 and 127 bytes in length inclusive

 

 

(excluding framing bits but including FCS bytes).

 

 

etherStatsPkts128to255Octets

The total number of packets (including bad packets) received

 

 

that were between 128 and 255 bytes in length inclusive

 

 

(excluding framing bits but including FCS bytes).

 

 

etherStatsPkts256to511Octets

The total number of packets (including bad packets) received

 

 

that were between 256 and 511 bytes in length inclusive

 

 

(excluding framing bits but including FCS bytes).

 

 

etherStatsPkts512to1023Octets

The total number of packets (including bad packets) received

 

 

that were between 512 and 1023 bytes in length inclusive

 

 

(excluding framing bits but including FCS bytes).

 

 

etherStatsPkts1024to1518Octets

The total number of packets (including bad packets) received

 

 

that were between 1024 and 1518 bytes in length inclusive

 

 

(excluding framing bits but including FCS bytes).

 

 

 

Rx Utilization

 

The percentage of receive (Rx) line bandwidth used by the

 

 

Ethernet ports during consecutive time segments.

 

 

 

Tx Utilization

 

Same as Rx Utilization, except calculated over the transmit

 

 

(Tx) line bandwidth.

 

 

Rx Alignment Errors

A count of frames received on a particular interface that are not

 

 

an integral number of bytes in length and do not pass the FCS

 

 

check.

 

 

 

Rx FCS Errors

 

A count of frames received on a particular interface that are an

 

 

integral number of bytes in length but do not pass the FCS

 

 

check.

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.
