The MAC address table of the switch records the MAC address, interface number, and VLAN of the device connected to the switch interface. Data can be quickly forwarded based on the MAC address table to reduce broadcast fluctuations. The MAC address table can be divided into three types: static MAC addresses, dynamic MAC addresses, and black hole MAC addresses. The static MAC address is manually configured by the Administrator to implement the unique ing between the

Preface This period of time has been studying how to improve the utilization of flow tablespace. I have never been able to think of good idea. One article compares the methods mentioned in the existing research, and here records the types of methods and their shortcomings. These methods are not limitedHow to improve the utilization of flow tablespaceTo extend the scopeHow to improve the matching success rate of the vswitch flow table.Background Soft

With network virtualization, the software switches (such as Open VSwitch) on the servers act like the edge switches. So, to gain insights into the network flow behavior, it becomes important to has some sort of flow monitoring technique t o Analyze the traffic through these switches. NetFlow and SFlow are the "most widely used flow monitoring approaches." To monitor the flows, the switches need to be configured to export and send the traffic data to a

As virtualization shifts the network edge from top of rack switches to software virtual switches running on the hypervisor S Visibility in the virtual switching layer is essential on order to provide network, server and storage management teams WI Th the information needed to coordinate resources and ensure optimal performance.The recent release of Citrix XenServer 6.0 provides an opportunity for a side-by-side comparison of SFlow and NetFlow Moni Toring Technologies Since both protocols be supp

TRUNK interface will also be sent to all interfaces and adjacent switches, resulting in excessive load on the switch, slow network, packet loss, and even paralysis. You can suppress MAC attacks by setting the maximum number of MAC addresses and the aging time of MAC addresses on the port. 1. Set the maximum number of MAC addresses that can be learnedBy setting the maximum number of MAC addresses learned from the Ethernet port, you can control the number of entries in the MAC address table maint

If the switch port of a vswitch is "err-disabled", it is likely that the workstation Nic device is not properly installed, then you can reinstall the NIC or update its driver. During normal work, the failure of workstations to access the Internet is generally caused by the switch port. Currently, many technical forums have provided some solutions to switch ports, these methods provide us with ideas and methods for efficient network management. However

In the network management work, the Internet cafe Switch configuration must be mastered and skillful. As this is a complicated process, some new network administrators may still lack experience. This document describes how to configure an internet cafe switch. Different types of switch Console Port location is not the same, the type of the Console port is also different, the vast majority of the use of RJ-45 port, but there are also a few using DB-9 serial port or DB-25 serial port. Next, perfo

This article describes in detail the vro and vswitch passwords. If you forget or are modified, how can you recover the vro and vswitch passwords? I hope this article will help you. Set vro Mode You can set a vro in five ways: 1. Set Through the SNMP network management workstation on the Ethernet; 2. The AUX port is connected to a MODEM and is connected to a remote terminal or a computer running the terminal

The first step in configuring VLAN 1 in an AVAYA_CAJUN vswitch to set a VLAN is to first create a VLAN. In an AVAYA vswitch, you must first create a vlan id and name. In fact, the name is only used to help identify VLANs, the switch identifies different VLANs by ID. After creating a VLAN, you can specify a port as the corresponding VLAN. The procedure is as follows: Step 1: set vlan

As the DHCP settings of the vswitch, the router switches the wireless route of the vswitch to the AP mode to connect to the wired router. Disable the DHCP service built in the wireless router for the Wireless AP to use, but sometimes the computer cannot get the IP address correctly. Why?1. Understanding SPI firewall 1. SPI, namely, full-state packet inspection firewall, refers to the situation through the s

these network devices to configure our own DHCP server, instead of configuring another server for the DHCP service. Next I will take the cisco switch (Other switches have not been tried) as an example to explain the specific practices: Assume that there are 400 hosts in a network, of which 255 are requested for allocation. The range is from 202.38.X.0 ~ 202.38.X.254, of which 202.38.X.1 is used to allocate to the Gateway. There are three servers A, B, and C in the network, and their fixed IP ad
