Specify data center uplink information. The uplink is enabled for management and data center networks.

Procedure

  1. If the uplink is an L2 connection, provide the following information.

    Field

    Description

    Uplink Type

    L2

    Uplink LAG Enabled

    It is recommended that you select this option.

    Uplink Ports

    Port numbers on the ToR switches that are connected to the uplink network. Enter a value ranging from 43 to 46.

    Uplink Speed

    Speed for uplink connections.

    Ensure that the management and external VLANs from Cloud Foundation are routable upstream.

  2. If the uplink is an L3 connection, provide the following information.

    Field

    Description

    Uplink Type

    L3

    Uplink LAG Enabled

    LAG (Link Aggregation Group) aggregates multiple links into a single bundle. You can enable this option if the speeds on the ports in your environment match. For example, if you have 4 uplink ports at 10G, you can get up to 40G with LAG enabled.

    Uplink Ports

    Port numbers on the ToR switches that are connected to the uplink network. Enter a value ranging from 51 to 54.

    Uplink Speed

    Speed for uplink connections.

    Uplink IP

    IP address of the uplink IP on the ToR switches.

    Mask IP

    Subnet mask for the uplink IP.

    Next Hop IP

    IP address of the uplink switch for the data center.

    For an L3 uplink, SDDC Manager configures a Switched VLAN Interface (SVI) for each requested VLAN and configures a static route between ToR 1 and the upstream router. The configured SVI and the configuration between the ToR and router is non-HA. You need set up a method to route traffic across the internet. This not automated during bring-up.

    You can set up iBGP between the ToR switches and an eBGP between each ToR switch and the upstream router. For information on the required configuration, see Example ToR Switch Output for L3 Configuration on Cisco ToR Switches (9372).
