Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

After the Aggregator powers on, it auto-configures and is operational with software features enabled, including:

• Ports: Ports are administratively up and auto-configured to operate as hybrid ports to transmit tagged and untagged VLAN traffic.For more information about how ports are numbered, refer to Port Numbering.
• Link aggregation: All uplink ports are configured in a single LAG (LAG 128).
• VLANs: All ports are configured as members of all (4094) VLANs. All VLANs are up and can send or receive layer 2 traffic. For more information, refer to VLAN Membership.
• Data center bridging capability exchange protocol (DCBx): Server-facing ports auto-configure in auto-downstream port roles; uplink ports auto-configure in auto-upstream port roles.
• Fibre Channel over Ethernet (FCoE) connectivity and FCoE initiation protocol (FIP) snooping: The uplink port channel (LAG 128) is enabled to operate in Fibre channel forwarder (FCF) port mode.
• Link layer discovery protocol (LLDP): Enabled on all ports to advertise management TLV and system name with neighboring devices.
• Internet small computer system interface (iSCSI)optimization.
• Internet group management protocol (IGMP) snooping.
• Jumbo frames: Ports are set to a maximum MTU of 12,000 bytes by default.
• Link tracking: Uplink-state group 1 is automatically configured. In uplink state-group 1, server-facing ports auto-configure as downstream interfaces; the uplink port-channel (LAG 128) auto-configures as an upstream interface. Server-facing links are auto-configured to be brought up only if the uplink port-channel is up.
• In VLT mode, port 9 is automatically configured as VLT interconnect ports. VLT domain configuration is automatic. This includes peer-link, configured MAC, backup link and setting every port channel as VLT port-channel.
