Switch 7700 Configuration Guide

38 CHAPTER 3: VLAN CONFIGURATION
Add Ethernet Ports to a VLAN
You can use the following command to add Ethernet ports to a VLAN.
Perform the following configuration in VLAN view.
For the meanings of the parameters related to the Ethernet ports and the specific
numbering rules of the ports, see
“Port Configuration” in this manual.
The port number following the key word to shall be no smaller than that before
to. And all the ports within the specified range shall be of the same type and exist.
The &<1-10> of the command specifies the repetition times of the parameter,
ranging from 1 to 10. In addition, you cannot specify any trunk ports.
By default, the system adds all the ports to a default VLAN, whose ID is 1.
Specify the Broadcast Suppression Ratio for VLAN
You can use the following command to specify the broadcast suppression ratio for
the VLAN.
Perform the following configuration in VLAN view.
Using this command, you can set the threshold for broadcast traffic that can pass
through the VLAN. This value is represented by the following percent: broadcast
traffic/the entire traffic passed this VLAN. The system discards the traffic that
exceeds the threshold to keep the broadcast traffic in a rational limit and maintain
the normal operation of network services.
The lower the value of the max-ratio parameter, the less broadcast traffic is
allowed to pass through. When it takes 100, the broadcast suppression will not be
performed on the specified VLAN.
By default, no broadcast suppression will be performed on any VLAN, that is, the
max-ratio takes 100.
