IPMI KVM on Allegro series 1000+

2025-04-30T13:47:13Z

Valerio:

Many Allegro Network Multimeters come with an on-board [https://en.wikipedia.org/wiki/Intelligent_Platform_Management_Interface IPMI] interface for basic hardware management.

This interface can be used to start, reboot, or shutdown the device without accessing the web interface. You can also access a virtual monitor to view the output on the console and use a virtual keyboard to interact with the device (KVM: ''keyboard, video, mouse''). This can be helpful for [[Performing a factory reset or configuration reset]].

The following table shows if the device supports IPMI and where the IPMI KVM port is located:

== Access to IPMI ==

The IPMI interface can be accessed via a LAN using the very top-left Ethernet port, usually above the USB ports. By default, the port will obtain an IP address via DHCP, but it can be reconfigured within the IPMI web interface.

If you point a browser to that IP address, a SuperMicro login will be presented where you can log into the interface:

[[File:Kvm login.png|640px]]

The default credentials are ADMIN/ADMIN but some newer devices come with a random password printed on the serial number sticker. On Allegro x300 series, the password is printed below a retractable plastic plate on top of the top-left 2.5 inch disk drive bay.

We recommend to change the default password into a secure one.

== Access to Health event log ==

There is an event log which shows all system health related events. In case of hardware problems, this can be useful to check.

[[File:Kvm event log.png|640px]]

[[File:Kvm event log2.png|640px]]

== Virtual console ==

The IPMI interface also allows to use a virtual console to see the monitor output and use a keyboard for input. This is useful when boot changes must be made, for example, a factory reset is required. It also allows to make screenshots from the boot process in case of problems.

[[File:Kvm console.png|640px]]

== Additional information ==

Please refer to the [http://www.supermicro.com/manuals/other/IPMI_Users_Guide.pdf official documentation] for more information.

The BMC can be updated manually, see [[IPMI BMC update|this page]] for more detailed information.

List of Supported Transceiver Modules

2024-10-11T11:17:19Z

Valerio:

== DISCLAIMER ==

Allegro Packets allows you to use third-party vendor modules in its appliances but guarantees only warranty and support for transceiver modules sold by Allegro Packets. Any malfunction or configuration issue with third-party modules are NOT covered by the warranty.

Allegro Packets does not restrict the use of third-party SFP+ modules for the devices. However, some hardware limitations apply which are described as follows:

== Built-in ports vs. expansion cards ==

The Allegro Network Multimeter 800/1000/1010/1200/3000/3010/3200/x310/x410 series have two on-board SFP+ ports which are restricted to original or branded '''Intel modules'''.

All non built-in ports are '''not''' vendor locked and can accept all transceiver modules. However, there are modules that do not work because of specific vendor extensions within the modules. This applies for all ports of the Allegro Network Multimeter x300, x310, x400, x410, x500 and x510 series and all expansion cards for the Allegro Network Multimeter 1000/1010/1200/3000/3010/3200.

The following table shows which kind of modules are supported by Allegro by
port type:

{| class="wikitable sortable"
|-
! Port type !!original or branded Intel modules !! non-Intel branded modules
|-
| built-in SFP+ ports || x || -
|-
| SFP+ expansion|| x || x
|-
| SFP28 expansion|| x || x
|-
| QSFP expansion|| x|| x
|-
| QSFP28 expansion|| x || x
|-
|}

The use of Intel branded modules is mandatory for the built-in SFP+ ports. These restrictions do not apply to the additional network expansion cards (2 port and 4 port SFP+, high precision GPS card, etc.) that are available for the Allegro Network Multimeter 1000 and 3000 series. These ports accept generic modules from a wide range of vendors.

Since auto-negotiation is often not available on 1G/10G SFP+ interfaces, it may be necessary to manually set the correct speed in the `Interface Stats` section of the user interface.

QSFP+ breakout cables are NOT supported.

== List of tested third-party modules ==

The following list of modules have been either tested by Allegro Packets or customers and have been reported to operate. Please be aware that this can change due new module revisions.

== Link status issues with different network equipment ==

=== Problem: 1G link is not coming up with 1G/10G SFP+ fiber modules ===
There is a known incompatibility with our 1G/10G SFP+ fiber modules when used with some Cisco equipment, such as a Cisco Nexus or Catalyst switch with 1G connectivity.

The solution is as follows:

* Disable auto-negotiation for the Cisco switch port which is connected to the Allegro device.
* Manually set speed to 1G for the Cisco switch port

Example configuration for Nexus:
configure terminal
interface ethernet x/yy
speed 1000
no negotiate auto
Actual commands depends on the Cisco model. Alternative commands are:
speed nonegotiates
set port speed 1000
Combinations known to work for 1G connectivity:

* Our 1G/10G SFP+ SR module in an Allegro SFP port (article number 700)
* Cisco GLC-SX-MMD in a Cisco switch
* Cisco switch settings applied as described above

Mirror Port, TAP and Packet Broker Installation

2024-10-11T11:03:35Z

Valerio:

This section describes the installation for network situations where the Allegro Network Multimeter receives traffic. It is referred to here as '''Mirror Port Installation''' or '''Mirror Port Mode''' but it is also applicable for Tap and Packet Broker installations.

The '''Mirror Port''' is a feature that is available on almost all manageable Ethernet switches.

== General ==

=== DISCLAIMER ===

The '''Mirror Port Mode''' depends on the quality of the Switch mirroring. Please check the Mirror Port statistics of your Switch if all packets have been forwarded. Allegro Network Multimeter measurements depend on accurate packet mirroring and may lead to incorrect statistics if the Mirror Port is not working as expected.

Allegro recommends a separate Tap or a Packet Broker if the quality of the Mirror Port cannot be guaranteed.

=== What is the '''Mirror Port Mode?''' ===

The Allegro Network Multimeter works in the '''Mirror Port Mode''' as a traffic receiving device. It will '''NOT''' forward any traffic on the measurement Ethernet ports.

=== How should the '''Mirror Port Mode''' be used? ===

The data plane ports of the Allegro Network Multimeter should be connected in '''Mirror Port Mode''' to one or multiple Mirror Ports on a Switch. The Allegro Network Multimeter management port needs to be connected to a standard Switch port or to an out-of-band management Switch.

See [[#Limitations]] for more details.

=== How do I configure the '''Mirror Port Mode?''' ===

Please refer to your Switch manual how to set up a Switch port as a mirror port.

The Allegro '''Mirror Port Mode''' can be configured at '''Settings''' → '''Global settings''' → '''Packet processing mode'''. The interfaces can be configured to '''Bridge mode''' or '''Sink mode'''. The '''Sink mode''' will disable packet forwarding and transmission on the Ethernet ports. Please switch to '''Sink mode''' and save the settings at the bottom of the page
[[File:Sink mode.png|800px]]

== Allegro Network Multimeter Data Plane Ports ==

=== Devices with built-in network ports ===

The '''Allegro 200, 500, 800, 1000, 1010, 1200, 3000, 3010, 3200, x310 and x410 series''' have built-in physical network ports.

|}

===Devices with port expansion cards===

All Allegro Network Multimeters with network card expansion slots support the '''Mirror Port Mode'''. All expansion cards have either '''2''' or '''4''' network ports.

===Bypass expansion cards===

The Allegro Network Multimeter bypass cards deliver a fail-over when the software bypass is not active in '''Bridge Mode''' ( see [[In-Line Installation|In-Line installation]] for more details ). The bypass is deactivated when the '''Mirror Port Mode / Sink Mode''' is active.

==Grouping of multiple links ( Trunk vs. separate links )==

By default, the Allegro Network Multimeter processes all incoming traffic as one big pipe and it does not use the port as an criteria to separate links. If you have connected separate links at the Allegro Network Multimeter, please use the virtual link grouping feature to specify which ports belong together.

This feature can also be used to forward multiple links with a Packet Broker to one Allegro port with VLANs as a separator.

==Advanced VLAN handling==

Some Switches remove the VLAN for one flow direction and keep it for the other when mirroring a VLAN trunk. Usually the Allegro Network Multimeter treats different packets of different VLANs as different links. The Allegro Network Multimeter can be configured to ignore the VLAN tag. This can be done at: '''Settings''' → '''Global settings''' → '''Expert settings''' → '''VLAN handling'''. Do not forget to save the settings at the bottom of the page!

[[File:Ignore vlan key.png|1200px]]

==Limitations==

===Switch limitations===

Please be aware that the Allegro Network Multimeter can only analyze packets that have been forwarded by the Switch port. Please also be aware that the exact packet timing and ordering depends on the Switch implementation. Allegro recommends the installation of a Tap to prevent any Switch side effects.

IPMI KVM on Allegro series 1000+

2024-10-11T10:25:11Z

Valerio:

Many Allegro Network Multimeters come with an on-board [https://en.wikipedia.org/wiki/Intelligent_Platform_Management_Interface IPMI] interface for basic hardware management.

This interface can be used to start, reboot, or shutdown the device without accessing the web interface. You can also access a virtual monitor to view the output on the console and use a virtual keyboard to interact with the device (KVM: ''keyboard, video, mouse''). This can be helpful for [[Performing a factory reset or configuration reset]].

The following table shows if the device supports IPMI and where the IPMI KVM port is located:

{| class="wikitable"

|}

== Access to IPMI ==

The IPMI interface can be accessed via a LAN using the very top-left Ethernet port, usually above the USB ports. By default, the port will obtain an IP address via DHCP, but it can be reconfigured within the IPMI web interface.

If you point a browser to that IP address, a SuperMicro login will be presented where you can log into the interface:

[[File:Kvm login.png|640px]]

The default credentials are ADMIN/ADMIN but some newer devices come with a random password printed on the serial number sticker. On Allegro x300 series, the password is printed below a retractable plastic plate on top of the top-left 2.5 inch disk drive bay.

We recommend to change the default password into a secure one.

== Access to Health event log ==

There is an event log which shows all system health related events. In case of hardware problems, this can be useful to check.

== Virtual console ==

The IPMI interface also allows to use a virtual console to see the monitor output and use a keyboard for input. This is useful when boot changes must be made, for example, a factory reset is required. It also allows to make screenshots from the boot process in case of problems.

In-Line Installation

This section describes the Allegro Network Multimeter In-Line installation.

== General ==

=== DISCLAIMER ===

Allegro recommends a separate Tap, a Packet Broker or Mirror Port for productive network links. Please use the '''In-Line''' only if the failure of a link does '''not''' cause problems.

=== What is the '''In-Line''' mode? ===

The '''In-Line mode''' allows the Allegro Network Multimeter to work as a transparent Bridge. Pairs of network ports form a group where all received traffic is forwarded immediately to the other port of the pair. It is the default configuration of the Allegro Network Multimeter that 2 port pairs build a transparent Bridge.

=== How should the '''In-Line mode''' be used? ===

The Allegro Network Multimeter can be installed between 2 network devices. As an example, the Allegro Network Multimeter can be installed between a Switch and an Access Point.
The '''In-Line mode''' is designed for links where the downtime of a link is '''not''' critical and where a delay and jitter of a few microseconds is acceptable. See [[#Limitations]] for more details.

=== How do I configure the '''In-Line mode?''' ===

The '''In-Line mode''' can be configured at '''Settings''' → '''Global settings''' → '''Packet processing mode'''. The interfaces can be configured to '''Bridge mode''' or '''Sink mode'''. The '''Bridge mode''' will enable packet forwarding to the Ethernet pair ports.

=== Devices with built-in network ports ===

The '''Allegro 200, 500, 800, 1000, 1010, 1200, 3000, 3010, 3200, x310 and x410''' have built-in physical network ports which run by default in '''Bridge mode'''.

== Expansion card options ==

=== Port expansion cards ===

Various 1G-100G Base-T and Base-X port expansion cards, featuring RJ45, SFP+, SFP28, QSFP and QSFP28 connection options, can be used.
All Allegro Netwok Multimeters with network card expansion slots support the '''In-Line mode''' by default. All expansion cards have either '''2''' or '''4''' network ports. Each card forms '''1''' or '''2''' Bridges. On expansion cards with '''4''' ports, the two left and the two right ports are the Bridge pairs.

=== Bypass Fail-over cards ===

The bypass cards for the Allegro Network Multimeter deliver an optical fail-over when the software bypass is not active. The bypass will be enabled when Bridge mode is active and triggered when the Allegro firmware is not running due to power off/loss, during the firmware upgrade process and/or most other instances of software/hardware failure.

=== PoE provisioning cards ===

Power over Ethernet bypass is not supported by the Allegro Network Multimeter. A PoE expansion card can be installed to support PoE. Alternatively a PoE injector can be used if PoE is required.

=== nanosecond time stamping cards ===
SFP+ 2-port extension cards with (GPS based) nanosecond timestamp support (100M/1G/10G)

== Limitations ==

=== Link setup ===

The Allegro Network Multimeter negotiates every port of a Bridge pair independently. This can lead to a link speed mismatch. As an example, an installation between a 1GBit/s Switch port and a 100 MBit/s VoIP telephone will lead by default to a speed mismatch. The Allegro Network Multimeter will show a warning if there is a speed mismatch.
You can check if there is a mismatch at '''Interface stats'''.

[[File:Interface speed mismatch.png|200px]]

=== Delay and jitter ===

Traffic forwarding is handled in software. This incurs a minor delay and jitter. The average delay and jitter is below 1 microsecond and does not have a measurable impact on most networks. The worst case jitter is below 50 microseconds. You can check average and worst case jitter at '''System info''' → '''Info''' → '''Load'''.

[[File:Loop duration.png|600px]]

=== Packet limitations ===

The software bypass does '''NOT''' forward :

* Packets with an MTU above 9000 bytes
* FcoE ( Fibre Channel over Ethernet ) packets ( ethertype 0x8906 )
* Ethernet flow control and pause frames ( ethertype 0x8808 )

=== Performance limitations ===

The software bypass can forward several million packets per second depending on the Allegro model. If packet loss on the bridge is not acceptable for multi-million packets per second, please use a Tap or similar.
