Traffic-Shape - Dell N1100-ON Reference Manual

traffic-shape

Use the traffic-shape command in Global Configuration mode and Interface
Configuration mode to specify the maximum transmission bandwidth limit
for the interface as a whole. To restore the default interface shaping rate
value, use the no form of this command.
Syntax
traffic-shape bw kbps
no traffic-shape
• bw — Maximum transmission bandwidth value expressed in Kbps.
(Range: 64 - 4294967295)
Default Configuration
This command has no default configuration.
Command Mode
Global Configuration mode, Interface Configuration (gigabitethernet, port-
channel, tengigabitethernet, fortygigabitethernet) mode
User Guidelines
Traffic shaping, also known as rate shaping, has the effect of smoothing
temporary traffic bursts over time so that the transmitted traffic rate is
bounded. This command implements a true egress shaper where bursts of
traffic are buffered and smoothed. Shaping occurs if the average rate exceeds
the configured limit or a burst exceeds 2% of the configured limit. Effectively,
all CoS queues are configured with the configured rate limit in the scheduler.
Traffic shaping may cause congestion and packet loss if the aggregate ingress
rate for an interface persistently exceeds the egress traffic shape rate.
Example
The following example rate limits interface gi1/0/1 to a maximum bandwidth
of 1024 Kbps.
console(config-if-Gi1/0/1)#traffic-shape 1024 Kbps
