Other Auto-Configured Settings

4 | Before You Start
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.
Ports 1 to 32 are internal server-facing ports, which can operate in either 1GbE or 10GbE
mode. Ports 33 to 56 are external ports auto-configured to operate by default as follows:
— The base-module ports operate in standalone 4x10GbE mode. You can configure
these ports to operate in 40GbE stacking mode. When configured for stacking, the
40GbE base-module ports cannot be used for uplinks.
— Ports on the 2-Port 40-GbE QSFP+ module operate only in 4x10GbE mode. They
cannot be used for stacking.
— Ports on the 4-Port 10-GbE SFP+ and 4-Port 10GBASE-T modules operate only in
10GbE mode.
For more information on how ports are numbered, see
• 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, see
• 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 FCF port mode.
• Link Layer Discovery Protocol (LLDP): Enabled on all ports to advertise management
TLV and system name with neighboring devices.
• iSCSI optimization
• 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.
• Stacking is not enabled by default and is supported in 40GbE mode only on the base-
module ports. To configure a switch stack, you must use the CLI. See
information.
