• Configure a port to monitor network traffic.
• Change Ethernet settings such as:
Fast MAC cache failover◦
◦ MAC refresh interval
◦ IGMP (Internet Group Management Protocol) snooping and idle timeout interval
◦ Loop protection
19.2.3 About logical interconnects
A logical interconnect is a single administrative entity that consists of the configuration for the
interconnects in an enclosure, which includes:
• The uplink sets, which connect to data center networks.
• The mapping of networks to physical uplink ports, which is defined by the uplink sets for a
logical interconnect.
• The downlink ports, which connect through the enclosure midplane to the servers in the
enclosure.
• The connections between interconnects, which are called stacking links. Stacking links can be
internal cables (through the enclosure) or external cables between the stacking ports of
interconnects.
For a server administrator, a logical interconnect represents the available networks through the
interconnect uplinks and the interconnect downlink capabilities through a physical server’s interfaces.
For a network administrator, a logical interconnect represents an Ethernet stacking domain,
aggregation layer connectivity, stacking topology, network reachability, statistics, and
troubleshooting tools.

Uplink sets
An uplink set defines a group of networks and physical ports on the interconnect in an enclosure.
An uplink set enables you to attach the interconnect to the data center networks. An uplink set
enables multiple ports to support port aggregation (multiple ports connected to a single external
interconnect) and link failover with a consistent set of VLAN networks.
