Qos Policy Map Counter

This feature is an extension of Qos Policy. It allows the user to configure Qos Policy Map counters. If a class-map is configured for a policer action then the conformed and non-conformed packet and byte counters are displayed for that class-map. Otherwise the number of packets and bytes hitting the class-map are shown. Platform compatibility DCS-7020R DCS-7280R DCS-7280R2 DCS-7500R DCS-7500R2 Configuration Following command allocates the Counter Engines for Qos which actually count and store the counter value. switch(config)#[no|default] hardware counter feature qos in Currently, there is not enough space in TCAM action bank for Qos counter feature. So to program the...

CFM: Default MIP

Connectivity Fault Management (CFM) is used in Virtual Bridged Local Area Networks for detecting, isolating, and reporting connectivity faults. Please refer IEEE 802.1ag standard for more details. This document introduces to the concept of Default Maintenance Intermediate Point and how to configure it on a switch for monitoring connectivity between various Maintenance Points within a Maintenance Domain. This feature is supported from EOS-4.20.1F onwards. Platform compatibility DCS-7020R DCS-7280R DCS-7280R2 DCS-7500R DCS-7500R2 Abbreviations MD Maintenance Domain MDL Maintenance Domain Level MP Maintenance Point MEP Maintenance End Point MIP Maintenance Intermediate Point CCM Continuity Check Message LTM Linktrace Message LTR Linktrace Reply...

WRED Support

WRED ( Weighted Random Early Detection ) is one of the congestion management techniques. It works at queue level to drop packets randomly after crossing given queue threshold even before queue is full. Without WRED, all newly arriving packets get tail dropped once the queue is full, which creates TCP global synchronization issue. WRED helps to avoid TCP global synchronization. Platform compatibility DCS-7050X DCS-7300X DCS-7250X Configuration This is configured at interface’s tx-queue level. The drop profile is defined by minimum-threshold, maximum-threshold and drop-probability. The units for thresholds can be given in segments ( 1 segment is equivalent to 208 bytes on T2...
