IStaX Software Product Specification
Product Overview
The IStaX turnkey software package is a fully managed L2 switch application for the IoT applications. This software
package can be customized to support different port configurations. It is built on Linux to ensure cost optimization
without compromising efficiency. The IStaX supports the following major capabilities.
• RedBoot bootloader
• U-boot bootloader
• Web or XMODEM update
Management is done using a web graphical user interface (GUI), command line interface (CLI), Simple Network
Management Protocol (SNMP), or JavaScript Object Notation-Remote Procedure Call (JSONRPC) running on the
internal MIPS24Kec CPU. The IStaX is highly integrated with switch features, such as QoS control lists (QCLs),
access control lists (ACLs), and super priority management queue.
This document provides an overview of the switch and software features of the IStaX software and lays the basis for
further specifications. The supported configuration details including parameters and limitations are beyond the scope
of this document. The module specific requirement specifications and configuration guides may be referred to for
obtaining these details.

Software Architecture
The CEServices software provides support for standalone switches. It consists of the following components.
• Operating system (Linux) for access to the hardware.
• Application programming interface (API) for a function library to control switches and PHYs.
• Control modules, such as port control, MSTP, and Virtual LAN (VLAN)—to implement product features and
protocols. These modules may include threads and provide a management API for configuration and monitoring.
• Management modules, such as CLI, web, JSON-RPC, and Simple Network Management Protocol (SNMP)—for
interfaces to the system based on the management API of the control modules.
The following illustration shows the architecture of the Microchip managed application software and a few control and
management modules.

Draft Product Specification DS30010225C-page 31
4. Port and System Capabilities
The following sections describe the port and system capabilities supported by the IStaX software.
4.1 Port Capability
The ports are equipped with the following capabilities.
• All copper ports can be configured as full-duplex or half-duplex.
• Copper ports operating at 10/100 Mbps support auto-sensing and auto-negotiation.
• Full-duplex, auto-sensing, and auto-negotiation are supported on 1000 Mbps ports.
• Full-duplex flow control is supported according to the IEEE 802.3x standard.
• Half-duplex flow control is supported using collision-based backpressure.
• LEDs for all the ports are driven by the SGPIO and Shift registers.
• Different port-based configurations are supported on all available ports. For more information, see 1. Supported
Features.
4.2 System Capability
The 6- to 52-port turnkey switch platform model switches can be supported using the IStaX software with wire speed
layer 2 Gigabit/Fast Ethernet switches, with an option to additionally support the PoE capability with partner vendors.
The turnkey switch software runs on Linux. The following system-wide operations are supported.
• Store-and-forward forwarding architecture.
• Configurable MAC address aging support (300 seconds default timeout value).
• Port packet-forwarding rates of 1488095 pps (1000 Mbps), 148810 pps (100 Mbps), and 14880 pps (10 Mbps).
• 128-MB system DDR SDRAM is recommended for a typical 24- to 48-port switch.
• 16-MB flash size is recommended for a typical 24- to 48-port switch.
• NOR-only, flash-based hardware designs are supported. NOR flash size of 64 MB is supported.

Firmware Upgrade
© 2020 Microchip Technology Inc.
and its subsidiaries
Draft Product Specification DS30010225C-page 32
5. Firmware Upgrade
The IStaX firmware, which controls the switch, can be updated using one of the following methods.
• Web, using the HTTP protocol
• CLI, using the TFTP client on the switch
The software image selection information includes the following:
• Image—the file name of the firmware image
• Version—the version of the firmware image
• Date—the date when the firmware was produced
After the software image is uploaded from the web interface, a web page announces that the firmware update is
initiated. After about a minute, the firmware is updated and the switch restarts.
While the firmware is being updated, web access appears to be defunct. The front LED flashes green/off with a
frequency of 10 Hz while the firmware update is in progress.
Note: 
Do not restart or power off the device at this time or the switch may fail to function.

Port Control
© 2020 Microchip Technology Inc.
and its subsidiaries
Draft Product Specification DS30010225C-page 33
6. Port Control
The following sections describe the port control features supported by the IStaX software.
6.1 NPI Port
The IStaX software supports the NPI port to manage the switch core. Any front port can be configured as an NPI port
through which frames can be injected from and extracted to an external CPU.
6.2 PCIe
The PCIe interface allows a back-to-back connection with an external CPU. The external CPU has read/write access
to device registers and can burst frame-data in (injection) and out (extraction) through memory-mapped injection/
extraction registers.
6.3 Dual CPU
The IStaX software supports a dual system where both the internal and external CPU are active at the same time.
6.4 SFP Detection
The IStaX software detects SFP at run time.
6.5 VeriPHY Support
The IStaX software provides VeriPHY support to run cable diagnostics to find cable shorts/opens and to determine
cable length.
6.6 PoE Support
The IStaX software provides PoE support to comply with the IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt
standards of enabling the supply of up to 90W per port and up the the total power budget.
6.7 POE with LLDP
The IStaX software allows automatic power configuration if the link partner supports PoE. When LLDP is enabled,
the information about the power usage of the PD is available, and then the switch can comply with or ignore this
information.
6.8 Unidirectional Link Detection (UDLD)
UDLD is used to determine the physical status of the link and to detect a unidirectional link.
A UDLD packet is sent to the port it links to for each device and for each port. The packet contains identity
information of the sender (device and port) and expected receiver identity information (device and port). Each port
checks that the UDLD packets it receives contain the identifiers of its own device and port.
The UDLD implementation conforms to the RFC5171 standard.
Note: 
RFC5171 is unclear about timers as well as messaging sequences. It is assumed that probe messages are initially
exchanged every second, and once link status is detected, probe messages are exchanged depending on message
time interval (by default 7 seconds).

Quality of Service (QoS)
© 2020 Microchip Technology Inc.
and its subsidiaries
Draft Product Specification DS30010225C-page 35
7. Quality of Service (QoS)
The following sections describe the rich QoS features supported by the IStaX software.
7.1 Port Policers
The QoS ingress port policers are configurable per port and are disabled by default. The software allows disable/
enable flow control on the port policer. Flow control is disabled by default. If flow control is enabled and the port is in
flow control mode, then pause frames are sent instead of discarding frames.
7.2 Scheduling and Shaping
Each egress port implements a scheduler that controls eight queues, one queue (priority) per QoS class. The
scheduler mode can be set to strict priority or weighted (modified-DWRR). Strict priority is selected by default. It is
possible to specify the weight for each of the queues (0–5).
Each egress port also implements a port shaper and a shaper per queue. The software allows disabling/enabling the
port and queue shaper as part of egress shaping. The port shaper and queue shaper are disabled by default.
It is possible to specify the maximum bit rate in kbps or mbps. The use of excess bandwidth for a queue is
configurable and is disabled by default.
The software also has the QoS leaky bucket egress shapers support per queue (0–7) as well as per port.
7.3 QCL Configuration
QoS classification based on basic classification can be overruled by an intelligent classifier called QoS Control List
(QCL).
The QCL consists of QCE entries where each entry is configured with keys and actions. The keys specify which part
of the frames must be matched and the actions specify the applied classification parameters.
When a frame is received on a port, the list of QCEs is searched for a match. If the frame matches the configured
keys, the actions are applied and the search is terminated.
The QCL configuration is a table of QCEs containing QoS control entries that classify to a specific QoS class on
specific traffic objects. A QoS class can be associated with a particular QCE ID.
7.4 Weighted Random Early Detection (WRED)
While the random early detection (RED) settings are configurable for queues 0–5, WRED is configurable to either
disable/enable, and is disabled by default.
The minimum and maximum percentage of the queue fill level or drop probability can be configured before WRED
starts discarding frames.
By specifying a different RED configuration for the queues (QoS classes), it is possible to obtain the WRED operation
between queues.
7.5 Tag Remarking
Tag remarking determines how an egress frame is edited before transmission. This includes the remarking of PCP
and DEI values in tagged frames.
When adding a VLAN tag, the software allows specifying a mode where the PCP and DEI values are taken from
Classified, Mapped, or Default. Classified is the default.
The QoS class DEI, DP Level to PCP, can also be mapped for QoS egress tag remarking per port when the
classification is set to Mapped.
