Hundred trillion switch to the desktop is currently the most common, with the promotion of network applications, the existing hundred trillion has been unable to meet the needs of Goxia, to have a quality upgrade must be upgraded to gigabit, online looking for this tp-link sg1008+, specifically selected a plastic shell, so easy to carry! In fact, to buy this gigabit switch is to carry the use, the exchange

A lot of friends are asking Huawei about the image of the switch. Through my existing data and documents, the various models of the switch mirroring methods are summarized. So that friends can easily check! Before the configuration, the basic concept of port mirroring is still a certain understanding!

1.4 Fabric port Mode
The Fabric port is the port between units in IRF. It is only used for interconnection between units and cannot connect users.

The total rate at which a message is sent or received by the port is indicated here at 8 levels, with a value range of 1~8, which means that when the port is working at a 10M rate, 1~

When you configure the watch port, if you do not specify a VLAN, the type of the observed port is local mirroring, and if you specify a VLAN, the type of the watch port is the remote mirror. 2. Configure the Mirror Port#将ETHERNET0/0/1----ETHERNET0/0/10 interface is configured as a mirrored

I. Port Mirroring concept: Port Mirror is used for network performance monitoring. It can be understood as follows: Establish an image relationship between port A and port B. In this way, data transmitted through port A will be copied to
Session 1 Port SecurityThe MAC address in the network is the constant physical address in the device, the control of the MAC address access control the switch port access, so port security is also the security of the Mac. In the switch, the cam (content addressable memory, t

To configure a vswitch port image, experts can understand the following knowledge about the vswitch port image configuration. You only need to complete the vswitch port image configuration in a few minutes. The local connection is also mentioned in this article.
Vswitch images such as 3026]Vswitches such as S2008/S2016/S2026/S2403H/S3026 support
bandwidth description:
When the Ethernet frame is 64 bytes, the fixed overhead of the 8 byte frame header and the 12 byte frame gap must be considered. Therefore, the packet forwarding rate of A 1-gigabit Ethernet port when forwarding a 64-byte packet is 1.488 Mpps. The 10-in-10 Gigabit Ethernet packet forwarding rate is 148.8 kpps.◆ For 10-Gigabit Ethernet, the packet forwarding rate of a wire speed
-Gigabit Switch with excellent performance does not have HOL. The test time is 15 seconds.
Deep test on address learning rate and address table
The address table thoroughly tests the number of MAC address tables for 24 full gigabit switches. The address learning rate checks the speed at which 24 full Gigabit Switches learn MAC addresses. We have used 24 ports A, B, and C of all gigabit switches. Ports A and B are used for sending learning frames and t
zabbix to monitor switch traffic. Instead, cacti is used. In fact, there is a problem with cacti, but you didn't meet it !!! The reason is that the data monitored by cacti is larger than that monitored by zabbix. The two sides are inconsistent. Back to question
In fact, to monitor the traffic on the vswitch port, pay attention to the two details.
1. The data unit is bit or bytes.
This concerns the issue of
If there is no port aggregation on the switch. Your two computers are connected by two wires. is a loop, and it affects both the switch and the connected computer. Therefore, the port aggregation function is very important for the Internet Café switch.
