The LAN Uplinks Manager provides a single interface where you can configure the connections between Cisco UCS and the LAN. You can use the LAN Uplinks Manager to create and configure the following:
Ethernet switching mode
Uplink Ethernet ports
Port channels
LAN pin groups
Named VLANs
Server ports
QoS system classes
Some of the configuration that you can do in the LAN Uplinks Manager can also be done in nodes on other tabs, such as the Equipment tab or the LAN tab.
Launching the LAN Uplinks Manager
Procedure
Step 1
In the
Navigation pane, click the
LAN tab.

Changing the Ethernet Switching Mode with the LAN Uplinks
Manager
Important:
When you change the Ethernet switching mode,
Cisco UCS Manager
logs you out and restarts the fabric interconnect. For a cluster configuration,
Cisco UCS Manager
restarts both fabric interconnects sequentially. The second fabric interconnect can take several minutes to complete the change in Ethernet switching mode and become system ready.
Procedure
Step 1

Configuring Named VLANs
Creating a Named VLAN with the LAN Uplinks Manager
In a
Cisco UCS instance with two switches, you can create a named VLAN that is
accessible to both switches or to only one switch.
Important:
You cannot create VLANs with IDs from 3968 to 4047. This range of
VLAN IDs is reserved.
The VLAN name is case sensitive.
Procedure
Step 1
In the LAN Uplinks Manager, click the
VLANs tab.
Step 2
On the icon bar to the right of the table, click
+.
If the
+ icon is disabled, click an entry in the
table to enable it.
Step 3
In the
Create VLAN dialog box, complete the following
fields:
Name
Description
VLAN Name/Prefix field
For a single VLAN, this is the VLAN name. For a range of VLANs, this is the prefix that the system uses for each VLAN name.
This name can be between 1 and 32
alphanumeric characters. You cannot use spaces or any special characters, and
you cannot change this name after the object has been saved.
Configuration options
You can select:
Common/Global—The VLANs apply to
both fabrics and use the same configuration parameters in both cases
Fabric A—The VLANs only apply to
fabric A.
Fabric B—The VLAN only apply to
fabric B.
Both Fabrics Configured
Differently—The VLANs apply to both fabrics but you can
specify different VLAN IDs for each fabric.
VLAN IDs field
To create one VLAN, enter a single numeric ID. To create multiple VLANs, enter individual IDs or ranges of IDs separated by commas. A VLAN ID can:
Be between 1 and 3967
Be between 4049 and 4093
Overlap with other VLAN IDs already defined on the
system
For example, to create six VLANs with the IDs 4, 22, 40, 41, 42, and 43, you would enter 4, 22, 40-43.
Important:
The VLAN IDs from 3968 to 4048 are reserved. You cannot
specify an ID within this range.
Sharing Type field
Whether this VLAN is subdivided into private or secondary VLANs. This can be:
none—This VLAN does not have any secondary or private VLANs.
primary—This VLAN can have one or more secondary VLANs, as shown in the Secondary VLANs area.
isolated—This is a private VLAN. The primary VLAN with which it is associated is shown in the Primary VLAN drop-down list.
Primary VLAN drop-down list
If the Sharing Type field is set to isolated, this is the primary VLAN associated with this private VLAN.
Check Overlap button
Click this button to determine whether the VLAN ID overlaps
with any other IDs on the system.
Step 4
Click
OK.
Cisco UCS Manager
adds the VLAN to one of the following
VLANs nodes:
The
LAN Cloud > VLANs node for a VLAN accessible to both fabric
interconnects.
The
Fabric_Interconnect_Name > VLANs node for a VLAN accessible to only one fabric
interconnect.
Deleting a Named VLAN with the LAN Uplinks Manager
If
Cisco UCS Manager includes a named VLAN with the same VLAN ID as the one you
delete, the VLAN is not removed from the fabric interconnect configuration
until all named VLANs with that ID are deleted.
Procedure
Step 1
In the LAN Uplinks Manager, click the
VLANs tab.
Step 2
Click one of the following subtabs, depending upon what type of
VLAN you want to delete:
Subtab
Description
All
Displays all VLANs in the
Cisco UCS
instance.
Dual Mode
Displays the VLANs that are accessible to both fabric
interconnects.
Fabric A
Displays the VLANs that are accessible to only fabric
interconnect A.
Fabric B
Displays the VLANs that are accessible to only fabric
interconnect B.
Step 3
In the table, click the VLAN you want to delete.
You can use the
Shift key or
Ctrl key to select multiple entries.
Step 4
Right-click the highlighted VLAN or VLANs and select
Delete.
Step 5
If
Cisco UCS Manager GUI
displays a confirmation dialog box, click
Yes.
Configuring QoS System Classes with the LAN Uplinks Manager
The type of adapter in a server may limit the maximum MTU supported. For example, network MTU above the maximums may cause the packet to be dropped for the following adapters:
The Cisco UCS CNA M71KR adapter, which supports a maximum MTU of 9216.
The Cisco UCS 82598KR-CI adapter, which supports a maximum MTU of 14000.
Procedure
Step 1
In the LAN Uplinks Manager, click the QoS tab.
Step 2
Update the following properties for the system class you want to configure to meet the traffic management needs of the system:
Note
Some properties may not be configurable for all system classes.
Name
Description
Enabled check box
If checked, the associated QoS class is configured on the
fabric interconnect and can be assigned to a QoS policy.
If unchecked, the class is not configured on the fabric
interconnect and any QoS policies associated with this class default to
Best Effort or, if a system class is configured with a Cos of 0, to the Cos 0 system class.
Note
This field is always checked for
Best Effort and
Fibre Channel.
Cos field
The class of service. You can enter an integer value between
0 and 6, with 0 being the lowest priority and 6 being the highest priority.
We recommend that you do not set the value to 0, unless you want that system class to be the default system class for traffic if the QoS policy is deleted or the assigned system class is disabled.
Note
This field is set to 7 for internal traffic and to
any for
Best Effort. Both of these
values are reserved and cannot be assigned to any other priority.
Packet Drop check box
If checked, packet drop is allowed for this class. If
unchecked, packets cannot be dropped during transmission.
This field is always unchecked for the
Fibre Channel class, which
never allows dropped packets, and always checked for Best Effort, which always allows dropped packets.
Weight drop-down list
This can be:
An integer between 1 and 10. If you enter an integer,
Cisco UCS
determines the percentage of network bandwidth assigned to the priority level
as described in the
Weight (%) field.
best-effort.
none.
Weight (%) field
To determine the bandwidth allocated to a channel,
Cisco UCS:
Adds the weights for all the channels
Divides the channel weight by the sum of all weights to
get a percentage
Allocates that percentage of the bandwidth to the
channel
MTU drop-down list
The maximum transmission unit for the channel. This can be:
An integer between 1500 and 9216. This value corresponds
to the maximum packet size.
fc—A predefined packet size of
2240.
normal—A predefined packet size of
1500.
Note
This field is always set to
fc for
Fibre Channel.
Multicast Optimized check box
If checked, the class is optimized to send packets to
multiple destinations simultaneously.
Note
This option is not applicable to the
Fibre Channel.
Step 3
Do one of the following:
Click OK to save your changes and exit from the LAN Uplinks Manager.
Click Apply to save your changes without exiting from the LAN Uplinks Manager.
