CDM-840 Remote Router MN-CDM840
Ethernet-based Remote Product Management Revision 3
6–43
Click VLAN to configure a VLAN ID assigned to the group. All traffic with the configured VLAN
ID will be routed through the QoS Group. If more than one QoS Group has the same VLAN
ID, then the subnet will be used to match the packet to the correct QoS Group.
The system Working Mode must be in BPM Mode in order to use the VLAN ID
to match packets to a QoS Group.
Click Subnet to configure a subnet assigned to the group. All traffic within the configured
subnet will be routed through this QoS Group. If the QoS Group subnets should overlap,
then the first QoS Group will be used for traffic.
To manage attributes:
Add an attribute Use the top row text boxes to enter the attribute (i.e., the VLAN ID or
Subnet IP/Mask). Click [Add] to create the attribute.
Delete an existing attribute Enter an Index (attribute) number in the text box. Click
[Delete] to execute removal of that attribute. The Attributes table will update accordingly.
Note the following:
VLAN Attributes Table (from left to right):
Column
Description
Index
This is the internal index number for the attribute. This number increments or
decrements automatically as you add or delete attributes.
Type
VLAN is the only available attribute.
Value
This is the assigned VLAN ID. Valid values are from 2 to 4095.
Subnet Attributes Table (from left to right):
Column
Description
Index
This is the internal index number for the attribute. This number increments or
decrements automatically as you add or delete attributes.
Type
Subnet is the only available attribute.
Value
This is the assigned subnet, in xxx.xxx.xxx.xxx/yy format.
The Attributes table entries are displayed based on which traffic has matched to this QoS Group.
The user-defined subnets entered into the QoS page need to be equal to or a superset of any of
the routes from the remotes i.e., there must be no overlaps. The user-defined VLAN ID must
be an exact match.
The examples that follow illustrate how the locally attached subnets associated with each
Ethernet will be reported as routes, unless the Management IP address has not been changed;
in which case, it will ignore that value.
Example #1
QoS Subnet
10.1.1.0/24
Remote Management IP Address
192.168.1.1
Remote’s Reported Routes
10.1.1.0/27
Result
Remote 192.168.1.1 will be added when traffic to that remote is sent
through the CTOG-250
