FAQs for Intel® Gigabit Ethernet Switch AXXSW1GB

Last Reviewed: 03-Mar-2016
Article ID: 000007248

Why do I get "Component Unfit" after installing a second switch?
Error: Component unfit
An active admin link between two switches can cause this error

Where is the ARP cache?
The ARP cache is under the switch Advanced Configuration - Layer 2 – Address table – Dynamic Addresses. More information can be found on page 74 (87 of 220) of the Intel® Gigabit Ethernet Switch AXXSW1GB Ethernet switch user guide

Is there a Fibre Channel option?
We currently offer Ethernet switches only.

What is the benefit of two Ethernet switches?
A second Ethernet switch can connect the servers to two separate physical networks. Separate VLANS or NIC teaming / bonding are recommended.

Do I have to add a mezzanine card to each compute module?
One Dual Gigabit Ethernet I/O Expansion Mezzanine Card AXXGBIOMEZ is required for each compute module that needs to access the second switch.

What kinds of teaming are supported?
Adapter Fault Tolerance and Adaptive Load Balancing are supported with a single switch. Switch Fault Tolerance is supported with dual switches and a mezzanine card, and is set via Device Manager or the NIC driver.

Can I aggregate NICs 1 & 2 and 3 & 4?
No. You can only use Switch Fault Tolerance to team NIC1 or NIC2, with NIC3 or NIC4.

Are there any security issues running multiple tenants, multiple domains, or multiple NATs?
No. The networking subsystem is specifically designed to treat each Compute Module as a unique entity.

Can I create a Link Aggregation Group (LAG) on the internal ports?
LAG can only be created on the external switch ports. For further information on LAG creation on the external ports, see Creating a multi-port trunk with an external switch.

Can the switch configuration be saved, exported or imported?
Yes. Use the Intel® Advanced Management Pack which is available with firmware 6.5. The Advanced Management Pack allows saving and exporting the existing Intel® Modular Server configuration, including the switch settings.

Are there external 10Gb ports?
The external ports are 1Gb. The internal 10Gb connections are not physically accessible.

How do I assign external port traffic, to a specific compute module?
Use VLAN membership, and put the external and the internal ports on a separate VLAN from the default.
Dashboard > Chassis Back > Switches > Advanced Configuration > Layer2 > Interface > VLAN. For further information on setting up VLANs, check How to create and use VLANs on the Intel® Modular Server.

Can dual ESMs be configured into one large switch for VLANs?
You cannot create an Inter-switch trunk using ports from ESM1 and ports from ESM2

Does Spanning Tree need to be disabled, when the switch has a LAG configured?
No. Spanning Tree can be enabled by port or LAG

Can both NICs be assigned to a VLAN

With a Mezzanine card, can 4 NICs be teamed or interconnected into a VLAN
Although you cannot aggregate all 4 NICs into a single trunk, you can enable fault tolerance between two NIC groups: NIC 1 and 2, and NIC 3 and 4.
