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

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	Interconnect, port 53

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.
