CLI Guide

Default Settings

The I/O Aggregator provides zero-touch conguration with the following default conguration settings:

• Default user name (root)

• Password (calvin)

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

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

• Read-only SNMP community name (public)

• Broadcast storm control (enabled)

• Unregistered Multicast Packets ooding (enabled)

• IGMP snooping in all VLANs except the default VLAN (enabled)

• VLAN conguration (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 congure an Aggregator, refer to the

Other Auto-Congured Settings

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

• VLANs: All ports are congured as members of all (4094) VLANs. All VLANs are up and can send or receive layer 2 trac. For more

information, refer to VLANs.

• Data Center Bridging Capability Exchange Protocol (DCBX)

• Fibre Channel over Ethernet (FCoE) connectivity

• FCoE Initiation Protocol (FIP) snooping

• Hybrid ports: Ports are administratively up and auto-congured to operate as hybrid ports to transmit tagged and untagged VLAN

trac.

• iSCSI optimization

• IGMP snooping

• Jumbo frames: Ports are set to a maximum MTU of 12,000 bytes by default.

• Link aggregation: All uplink ports are congured in a single LAG (LAG 128).

• Link Layer Discovery Protocol (LLDP): Enabled on all ports.

• Link tracking: Enables server-facing links to be brought up only if the uplink port-channel (LAG 128) is up.

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 conguration for DCB. The Aggregator auto-congures DCBX port roles to match the DCBX

conguration in the ToR switches to which it connects through its uplink ports.

The Aggregator supports DCB only in standalone mode and not in the stacking mode.
