TRAFFIC SEGMENTATION COMMANDS 
Traffic segmentation allows you to further sub-divide VLANs into smaller groups of ports that will help to reduce traffic on the 
VLAN.  The VLAN rules take precedence, and then the traffic segmentation rules are applied. 
Command Parameters 
config traffic_segmentation  [<portlist> | all] forward_list [null | all | <portlist>] 
show traffic_segmentation  {<portlist>} 
Each command is listed, in detail, in the following sections. 
config traffic_segmentation 
Purpose  Used to configure traffic segmentation on the Switch. 
Syntax 
config traffic_segmentation [<portlist> | all] forward_list [null | 
all | <portlist>] 
Description The config traffic_segmentation command is used to configure 
traffic segmentation on the Switch. 
Parameters 
<portlist> − Specifies a port or range of ports that will be configured 
for traffic segmentation.  
all – Specifies all ports on the Switch. 
forward_list  − Specifies a port or range of ports that will receive 
forwarded frames from the ports specified in the portlist, above. 
Restrictions 
•  null − No ports are specified  
•  all – Specifies all ports on the Switch. 
•  <portlist>  − Specifies a range of ports for the forwarding list. 
This list must be on the same switch previously specified for 
traffic segmentation (i.e. following the <portlist>  specified 
above for config traffic_segmentation). 
Only administrator-level users can issue this command. 
Example usage: 
To configure ports 1 through 10 to be able to forward frames to port 11 through 15: 
DGS-3400:4# config traffic_segmentation 1-10 forward_list 11-15 
Command: config traffic_segmentation 1-10 forward_list 11-15 
 
Success. 
DGS-3400:4# 
 
 
show traffic_segmentation 
Purpose  Used to display the current traffic segmentation configuration on the 
Switch. 
Syntax 
show traffic_segmentation {<portlist>}  
Description The show traffic_segmentation command is used to display the 
current traffic segmentation configuration on the Switch. 
Parameters 
<portlist> − Specifies a port or range of ports for which the current traffic 
segmentation configuration on the Switch will be displayed.   
Restrictions  The port lists for segmentation and the forward list must be on the same 
Switch.
