Administrator Guide

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.

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, and disabling

storm control on interfaces connected to an iSCSI equallogic (EQL) 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.

Link Aggregation

In Standalone, VLT, and Stacking modes, all uplink ports are configured in a single LAG (LAG 128). There

can be multiple uplink LAGs in programmable-mux mode. Server-facing ports are auto-configured as

part of link aggregation groups if the corresponding server is configured for LACP-based NIC teaming.

Static LAGs are supported in PUX mode.

NOTE: The recommended LACP timeout is Long-Timeout mode.

Link Tracking

By default, all server-facing ports are tracked by the operational status of the uplink LAG. If the uplink LAG

goes down, the Aggregator loses its connectivity and is no longer operational; all server-facing ports are

brought down.

NOTE: If installed servers do not have connectivity to a ToR switch, check the Link Status LED of

uplink ports on the Aggregator. If all LEDs are ON, check the LACP configuration on the ToR switch

that is connected to the Aggregator to ensure the LACP is correctly configured.

VLANs

By default, all Aggregator ports belong to all 4094 VLANs and are members of untagged VLAN 1. You can

use the CLI or CMC interface to configure only the required VLANs on a port.
