Link Aggregation Group (LAG) direct link topology

This section covers details about the Link Aggregation Group (LAG) direct link topology.

Based on the LAG direct link topology and the uplink bandwidth option (10 Gbps or 40 Gbps) for the customer data center connection, use the following port connectivity diagram:

Figure 1. Customer data center connection: LAG direct link


Diagrams of port connectivity for customer data center connection, LAG direct link
Note
  • The interconnect switch requires a single 1 Gbps copper connection (RJ45) from the out-of-band (OOB) management port on the interconnect switch to the management switch or the OOB interconnect network.

  • Ports 51 and 54 of the interconnect switch do not have LED status indicators.

The following table provides the ports from the interconnect switch which need to be connected to the customer data center network.

Uplink bandwidth option

Device

Network interconnect ports

10 Gbps data center network

Primary device

Interconnect, Mgmt port

Interconnect, port 48

Secondary device

Interconnec,t port 46

40 Gbps data center network

Primary device

Interconnect, Mgmt port

Interconnect, port 54

Secondary device

Note

Choose either the 10 Gbps or the 40 Gbps option.

Table 1. LAG direct link topology specifications

Configuration

Both sides configured as trunk ports with LAG

OOB Interconnect Network

One access port for the interconnect switch connected to the management switch or VLAN

Requirements

  • LACP enabled

  • STP required

Note

The uplink VLAN must be different than the OOB management VLAN.
