3.2.7 Mirror Configuration  

 

 

Fig. 3.13

 

Function Name:

 Mirror 

Setting

 

 

Function  

Mirror Configuration is used to monitor the traffic on

 

Description

the network. For example, assume that Port A is a ‘sniffer’  port 

and 

 

 

 

Port B is the Source Port; configuring a mirror setting allows the traffic 

 

 

 

passed by Port B to be copied to Port A for monitoring purposes

 

 

 

Parameter Sniffer 

Mode

 Description

 

* Used for the activation or de-activation of the Port Mirror  

 

 

 

  function. Default is disable    

 

 

 

Sniffer Port

 

 

 

* Used to set up the port that will perform the monitoring.  

 

 

 

  Port 1-16 can be used; the default is Port 1 

 

 

 

Source Port

  

Used to 

set up the port that will be monitored. Select the  

 

 

  check box (

;

) under the port label. The valid port range  

 

 

  is ports 1-16.  

 

 

3.2.8. Quality of Service (QoS) Configuration

 

The 

switch

 offers powerful QoS functions including: VLAN tagged priority for 8 levels, TOS 

field IP header (equal DSCP low 3 bits) on Layer 3 network framework, 6 types of layer 4 
network transmission events, and IP DiffServe QoS services.  

In the Quality of Service (QoS) Configuration management interface there is an option 
named ”Default Class”. Once you have selected one of the four QoS methods, this Default 
Class is used to group packets that do not match any of the QoS rules defined for the 
particular QoS method selected. For instance, if you set:
