Table 11-10 CE-100T-8, CE-MR-6, and ML-100T-8 POS Ports Parameters for GFP-F Mode (continued)

Parameter

Definition

 

 

txTotalPkts

The total number of transmit packets.

 

 

ifInDiscards

The number of inbound packets that were chosen to be discarded

 

even though no errors had been detected to prevent their being

 

deliverable to a higher-layer protocol.

 

 

iflnErrors

Number of inbound packets discarded because they contain errors.

 

 

ifOutOctets

The total number of transmitted octets, including framing packets.

 

 

rxTotalPkts

The total number of receive packets.

 

 

ifOutOversizePkts

Number of packets larger than 1518 bytes sent out into SDH.

 

Packets larger than 1600 bytes do not get transmitted.

 

 

gfpStatsRxSBitErrors

Receive frames with single bit errors (cHEC, tHEC, eHEC).

 

 

gfpStatsRxMBitErrors

Receive frames with multibit errors (cHEC, tHEC, eHEC).

 

 

gfpStatsRxTypeInvalid

Receive frames with invalid type (PTI, EXI, UPI).

 

 

gfpStatsRxCRCErrors

Receive data frames with payload CRC errors.

 

 

gfpStatsRxCIDInvalid

Receive frames with invalid CID.

 

 

gfpStatsCSFRaised

Number of Rx client management frames with client signal fail

 

indication.

 

 

ifInPayloadCRCErrors

The number of receive data frames with payload CRC errors.

 

 

ifOutPayloadCRCErrors

The number of transmit data frames with payload CRC errors.

 

 

gfpStatsRxFrame

Number of received GFP frames.

 

 

gfpStatsTxOctets

Number of GFP bytes transmitted.

 

 

ifOutDiscards

Number of outbound packets that were chosen to be discarded even

 

though no errors had been detected to prevent their transmission. A

 

possible reason for discarding such packets could be to create buffer

 

space.

 

Note ifOutDiscards is not supported on ML cards.

 

 

11.6.1.5 CE-100T-8, CE-MR-6, and ML-100T-8 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 POS Ports Utilization window provides an Interval drop-down list that enables you to set time intervals of 1 minute, 15 minutes, 1 hour, and 1 day. Line utilization for POS ports 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).

Refer to Table 11-7 on page 11-22for maxBaseRate values for VC high-order path circuits.

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

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.
