The ABI of the Solaris/Linux operating system is Sytem v abi.
Concept: SFP (Stack Frame Pointer) Stack framework Pointer
To understand SFP correctly, you must understand:
Concept of IA32 Stack
Functions of 32-bit register ESP/EBP in CPU
How the PUSH/POP command affects the stack
How CALL/RET/LEAVE and other commands affect the stack
As we know:

Huawei Switch Model Daquan LI (Lite software Image) indicates that the device is a weak feature version. The SI (standard software Image) indicates that the device is a standardized version and contains the underlying features. EI (Enhanced software Image) indicates that the device is an enhanced version and contains some advanced features.

Although from the perspective of applications, enterprises have gradually increased their requirements for data, voice, and video fusion from Gigabit to desktop, high prices stop some price-sensitive enterprises. To solve this problem, zhibang technology has launched the New SMC 8024L, a fully gigabit network-managed switch. This product is an intelligent network management switch with a layer-2 wire speed of Gbit/s. Its biggest characteristic is its good cost performance and excellent network m
Cisco SLM2024 offers 24 10/100/1000mbps RJ-45 connectors and 2 shared Gigabit Optical Small package hot-swappable (SFP) uplink interfaces, 48Gbps switching capacity, bidirectional gigabit forwarding without blocking, and full graphical web configuration interface; General features like VLAN, QoS, IGMP, broadcast suppression, etc. are readily available.
The SLM2024 supports 802.1x and port security,
. However, if you disassemble the Solaris/Linux binary files, you will find that the function return values are saved using eax.This is not accidental. It is determined by the operating system's Abi (Application binary interface.The ABI of the Solaris/Linux operating system is sytem v Abi.

It includes the following set of logical channels for the transmission of public control signaling.

System File Protection
Installation programs that are not part of the operating system can overwrite shared system files, even when it is incorrect to do so. This has been a common problem in the history of the Microsoft? Windows? Operating systems. overwriting shared system files with older versions or modified versions of the file can result in unpredictable system performance that ranges from application errors to operating system crashes.
In network management, network optimization and network obstacle elimination are the two most challenging tasks. I have been engaged in network management for nearly ten years and have accumulated many typical cases of network faults. I share this platform for your reference. Today, let's talk about common faults in the vswitch connection process.
Fault 1: Switch cascade fault
Fault situation: a customer adds available Ethernet interfaces by connecting the vswitch to the cascade mode. After a ne
1: What are the characteristics of TDD technology?
L Time Division Duplex (TDD): distinguishes uplink and downlink based on different time slots
P advantages
N when the upstream and downstream services are asymmetrical, different quantities of time slots can be flexibly allocated to the upstream and downstream operations, resulting in high spectrum efficiency.
N uplink and downlink use the same frequency ca
frequencies and between systems requires compression mode.
The compression mode is introduced to perform cross-frequency measurement or cross-system measurement under FDD. Because a receiver can only work on a group of sending and receiving frequencies at the same time, to measure signals of other frequencies, the receiver must stop working and switch the frequency to the target frequency for measurement. To ensure the normal transmission of the downstream signal, the original signal must be se
scheme, can be implemented through a physical network port to achieve the functions of these four ports, which will greatly reduce the complexity of the network, but also a good solution.1) The physical port of the Vxlan can be unnecessary, because the Vxlan transfer requires an IP layer address, you can create internal port (L3vxlan) on Br-uplink, and configure the port with an IP address to enable the transmission of Vxlan tunneling information.2)
Optical fiber jumper (also known as optical fiber connector) is a Connector Plug installed on both ends of the optical fiber, used to achieve optical link activity connection; one end is equipped with a plug is called pigtails.
