Default Settings

The I/O Aggregator provides zero-touch configuration with the following default configuration settings:

• default user name (root)

• password (calvin)

• VLAN (vlan1) and IP address for in-band management (DHCP)

• IP address for out-of-band (OOB) management (DHCP)

• read-only SNMP community name (public)

• broadcast storm control (enabled in Standalone mode and disabled in VLT mode)

• IGMP multicast flooding (enabled)

• VLAN configuration (in Standalone mode, all ports belong to all VLANs)

You can change any of these default settings using the CLI. Refer to the appropriate chapter for details.

NOTE: You can also change many of the default settings using the chassis management controller

(CMC) interface. For information about how to access the CMC to configure the aggregator, refer

to the Dell Chassis Management Controller (CMC) User’s Guide on the Dell Support website at

Other Auto-Configured Settings

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 from 1 to 8 are internal server-facing ports.

– Ports from 9 to 12 are external ports.

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.
