www.dell.com | support.dell.com 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 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, see 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 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 Stacking for more information.
DCB Support DCB enhancements for data center networks are supported to eliminate packet loss and provision links with required bandwidth. The Aggregator provides zero-touch configuration for DCB. The Aggregator auto-configures DCBX port roles as follows: • Server-facing ports are configured as auto-downstream interfaces. • Uplink ports are configured as auto-upstream interfaces. In operation, DCBX auto-configures uplink ports to match the DCB configuration in the ToR switches to which they connect. The Aggregator supports DCB only in standalone mode; DCB is not supported in stacking mode. FCoE Connectivity and FIP Snooping Many data centers use Fibre Channel (FC) in storage area networks (SANs). Fibre Channel over Ethernet (FCoE) encapsulates Fibre Channel frames over Ethernet networks. On an Aggregator, the internal ports support FCoE connectivity and connect to the converged network adapter (CNA) in blade servers. FCoE allows Fibre Channel to use 10-Gigabit Ethernet networks while preserving the Fibre Channel protocol. The Aggregator also provides zero-touch configuration for FCoE configuration. The Aggregator auto-configures to match the FCoE settings used in the ToR switches to which it connects through its uplink ports. FIP snooping is automatically configured on an Aggregator. The auto-configured port channel (LAG 128) operates in FCoE forwarder (FCF) port mode. iSCSI Operation Support for iSCSI traffic is turned on by default when the Aggregator powers up. No configuration is required. When the Aggregator powers up, it monitors known TCP ports for iSCSI storage devices on all interfaces. When a session is detected, an entry is created and monitored as long as the session is active. The Aggregator also detects iSCSI storage devices on all interfaces and auto-configures to optimize performance. Performance optimization operations, such as Jumbo frame size support, STP port-state fast, and disabling of storm control on interfaces connected to an iSCSI storage device, are applied automatically. CLI configuration is necessary only when the configuration includes iSCSI storage devices that cannot be automatically detected and when non-default QoS handling is required. Before You Start | 5
