whitelist session-car e-trunk-ipv4

Format

whitelist session-car e-trunk-ipv4 { cir cir-value | cbs cbs-value | pir pir-value | pbs pbs-value } ^*

undo whitelist session-car e-trunk-ipv4 [ { cir cir-value | cbs cbs-value | pir pir-value | pbs pbs-value } ^* ]

Parameters

Parameter	Description	Value
cir cir-value	Specifies a committed information rate (CIR), that is, the average rate at which packets can be transmitted or forwarded.	The value is an integer that ranges from 0-1000000, in kbit/s. The default value is 128.
cbs cbs-value	Specifies a committed burst size (CBS) for instantaneously transmitted packets.	The value is an integer that ranges from 0-9000000, in bytes. The default value is 25600.
pir pir-value	Specifies a peak information rate (PIR), that is, the highest rate at which packets can be transmitted or forwarded.	The value is an integer that ranges from 0-1000000, in kbit/s. The default value is 1500. It is recommended that <i>pir-value</i> be greater than or equal to <i>cir-value</i>.
pbs pbs-value	Specifies a peak burst size (PBS), that is, the peak burst traffic that can instantaneously pass through.	The value is an integer that ranges from 0-9000000, in bytes. The default value is 187,500. It is recommended that <i>pbs-value</i> be greater than or equal to <i>cbs-value</i>.

Parameter

Description

Value

cir cir-value

Specifies a committed information rate (CIR), that is, the average rate at which packets can be transmitted or forwarded.

cbs cbs-value

Specifies a committed burst size (CBS) for instantaneously transmitted packets.

The value is an integer that ranges from 0-9000000, in bytes. The default value is 25600.

pir pir-value

Specifies a peak information rate (PIR), that is, the highest rate at which packets can be transmitted or forwarded.

The value is an integer that ranges from 0-1000000, in kbit/s. The default value is 1500. It is recommended that pir-value be greater than or equal to cir-value.

pbs pbs-value

Usage Guidelines

Usage Scenario

For an IPv4 network, when a large number of E-Trunk packets are sent to the CPU, you can run the whitelist session-car e-trunk-ipv4 command to adjust bandwidth parameters for CAR for E-Trunk sessions to ensure that E-Trunk packets can be properly sent to the CPU.

Precautions

In normal cases, adjusting the default bandwidth parameters for CAR for E-Trunk sessions is not recommended. Use the default values instead.

Example

# Configure bandwidth parameters for CAR for E-Trunk sessions.
