New and Changed Information
The following table provides an overview of the significant changes made to this configuration guide. The table does not provide an exhaustive list of all changes made to this guide or all new features in a particular release.
Feature |
Release |
Description |
Where Documented |
---|---|---|---|
FEX-Based ACL Classification |
7.0(3)N1(1) |
The FEX-Based ACL Classification feature uses TCAM resources on a FEX to perform ACL-based packet classification of incoming packets on the switch. |
|
Buffer Utilization Histogram |
7.0(2)N1(1) |
The Buffer Utilization Histogram feature allows you to analyze the maximum queue depths and buffer utilization in the system in real time. Instantaneous or real time buffer utilization information is supported. |
|
IPv6 ACL logging |
7.0(1)N1(1) |
The IPv6 ACL logging feature allows you to monitor ACL flows and to log dropped packets on an interface. |
|
Micro-Burst Monitoring |
7.0(0)N1(1) |
The micro-burst monitoring feature allows you to monitor traffic on a per-port basis for both ingress and egress ports and to detect unexpected data bursts within a very small time window (micro-seconds). This allows you to detect flows in the network that are at risk of data loss, and that may require extra bandwidth |
|
Configuring Switch Latency Monitoring |
7.0(0)N1(1) |
The switch latency monitoring feature marks each ingress and egress packet with a timestamp value. To calculate the latency for each packet in the system the switch compares the ingress with the egress timestamp. The feature allows you to display historical latency averages between all pairs of ports, as well as real-time latency data. |
|
WRED Explicit Congestion Notification |
7.0(0)N1(1) |
Weighted Random Early Detection (WRED), and Explicit Congestion Notification (ECN) provide congestion control and avoidance solutions for applications that are sensitive to delay or packet loss (for instance, interactive traffic including Telnet, web-browsing, and transfer of audio and video data). |
