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 This 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. The port list is specified by listing the lowest switch number and the
beginning port number on that switch, separated by a colon. Then the highest switch
number, and the highest port number of the range (also separated by a colon) are
specified. The beginning and end of the port list range are separated by a dash. For
example, 1:3 specifies switch number 1, port 3. 2:4 specifies switch number 2, port 4.
1:3–2:4 specifies all of the ports between switch 1, port 3 and switch 2, port 4 – in
numerical order. Non–contiguous portlist entries are separated by a comma. (ex: 1:1–
1:3,1:7–1:9)
all – Specifies all ports on the Switch. Non–contiguous portlist entries are separated by a
comma. (ex: 1:1–1:3,1:7–1:9)
forward_list − Specifies a port or range of ports that will receive forwarded frames from
the ports specified in the portlist, above.
• 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). The port list is specified by
listing the lowest switch number and the beginning port number on that switch,
separated by a colon. Then the highest switch number, and the highest port number
of the range (also separated by a colon) are specified. The beginning and end of
the port list range are separated by a dash. For example, 1:3 specifies switch
number 1, port 3. 2:4 specifies switch number 2, port 4. 1:3–2:4 specifies all of the
ports between switch 1, port 3 and switch 2, port 4 – in numerical order. Non–
contiguous portlist entries are separated by a comma. (ex: 1:1–1:3,1:7–1:9)
Restrictions Only Administrator and Operator-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–3426:5#config traffic_segmentation 1:1–1:10 forward_list 1:11–1:15
Command: config traffic_segmentation 1:1–1:10 forward_list 1:11–1:15
Success.
