LAN Uplinks Manager
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
Changing the Ethernet Switching Mode with the LAN Uplinks Manager
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. The second fabric interconnect can take several minutes to complete the change in Ethernet switching mode and become system ready. The configuration is retained.
While the fabric interconnects are rebooting, all blade servers will lose all LAN and SAN connectivity, causing a complete outage of all services on the blades. This may cause the operating system to crash.
Configuring a Port with the LAN Uplinks Manager
All of the port types listed are configurable on both the fixed and expansion module, including server ports, which are not configurable on the 6100 series fabric interconnect expansion module, but are configurable on the 6200 series fabric interconnect expansion module.
Configuring Server Ports
Enabling a Server Port with the LAN Uplinks Manager
This procedure assumes that the port has been configured as a server port, but is disabled.
Disabling a Server Port with the LAN Uplinks Manager
Unconfiguring a Server Port with the LAN Uplinks Manager
Configuring Uplink Ethernet Ports
Enabling an Uplink Ethernet Port with the LAN Uplinks Manager
This procedure assumes that the port has been configured as an uplink Ethernet port, but is disabled.
Disabling an Uplink Ethernet Port with the LAN Uplinks Manager
The disabled port is removed from the list of enabled interfaces and returned to the Unconfigured Ports list.
Unconfiguring an Uplink Ethernet Port with the LAN Uplinks Manager
The disabled port is removed from the list of enabled interfaces and returned to the Unconfigured Ports list.
Configuring Uplink Ethernet Port Channels
Creating a Port Channel with the LAN Uplinks Manager
Enabling a Port Channel with the LAN Uplinks Manager
Disabling a Port Channel with the LAN Uplinks Manager
Adding Ports to a Port Channel with the LAN Uplinks Manager
Removing Ports from a Port Channel with the LAN Uplinks Manager
Deleting a Port Channel with the LAN Uplinks Manager
Configuring LAN Pin Groups
Creating a Pin Group with the LAN Uplinks Manager
In a system with two fabric interconnects, you can associate the pin group with only one fabric interconnect or with both fabric interconnects.
Configure the ports and port channels with which you want to configure the pin group. You can only include ports and port channels configured as uplink ports in a LAN pin group.
What to Do Next
Include the pin group in a vNIC template.
Deleting a Pin Group with the LAN Uplinks Manager
Configuring Named VLANs
Creating a Named VLAN with the LAN Uplinks Manager
In a Cisco UCS domain with two switches, you can create a named VLAN that is accessible to both switches or to only one switch.
You cannot create VLANs with IDs from 3968 to 4047. This range of VLAN IDs is reserved.
VLANs in the LAN cloud and FCoE VLANs in the SAN cloud must have different IDs. Using the same ID for a VLAN and an FCoE VLAN in a VSAN results in a critical fault and traffic disruption for all vNICs and uplink ports using that VLAN. Ethernet traffic is dropped on any VLAN which has an ID that overlaps with an FCoE VLAN ID.
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.
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:
| ||||||||||
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 the 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:
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:
| ||||||||||||||||||||||||||
Step 3 | Do one of the following: |
