problems when using such low-end devices separately. Workgroup-level optical fiber switch Fiber switches provide the ability to cascade many switches into a large-scale Fabric. By connecting one or more ports of two vswitches, all ports connected to the vswitch can see a unique network image, any node on this Fabric can communicate with other nodes. Essentially, through cascade switches, a large, virtual,

Mirror Port configurationMost switches support mirroring technology, which allows for easy troubleshooting of the switch. We call it "mirroring" or "Spanning". Mirroring is the copying of traffic from one port on the switch to the other (mirror port) for monitoring.CISCO3550

allows packets sent by default VLAN without tags. 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. 2 Application of Hybrid port Mode By introducing the various link port modes

from the source VLAN list; (4) A VLAN in the inactive state cannot participate in span tasks; (5) For a source VLAN set to input data flow monitoring, routing information packets from other VLANs are not mirrored, and the routing information packets sent from the VLAN set to the output data stream are also not mirrored. In other words, the VLAN-based span task mirrors only packets going in and out of the two-tier exchange

range is 1~4094. 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

The configuration mode of the switch can be broadly divided into two categories: one is the configuration mode represented by the Cisco switch, and the other is the configuration mode represented by Huawei and the H3C switch. In fact, the two configuration modes are not fundamentally different, but the configuration of the command name and configuration of the wa

This chapter describes the details. 3. Principle of L3 remote Port Mirroring Layer-3 remote port images are implemented through the re

For many enterprise network administrators, switches are naturally the most commonly used equipment. So how much do you know about vswitches? Next we will use an example to discuss the practice of vswitch port configuration and access security protection! Scenario: There is a CISCO3550 switch in a certain unit. For the sake of network security, the security requirements for some ports are high, that is, on

the show mac-address-table command. For example: 　　 Code: switch# Show Mac-address-table Mac Address Table ——————————————- Vlan Mac Address Type Ports ..................................................................... 1 0007.e9e2.2d7d DYNAMIC FA0/5 1 0009.0f30.07e9 DYNAMIC FA0/48 1 0009.5bbc.af04 DYNAMIC Fa0/28 1 00e0.bb2c.30d1 DYNAMIC GI0/1 1 00e0.bb2c.3e5f DYNAMIC GI

cannot access this port. 4. Method of cracking: there are many ways to crack the network, mainly by changing the MAC address of the new computer Nic, but I think, in practice, this method does not have any function. The reason is very simple. If it is not a network administrator, other general personnel cannot pay attention to the MAC address of a valid computer at ordinary times, generally, you cannot enter a valid computer to obtain the MAC addre

When connecting a computer to a switch, it may take 30 seconds or more for the computer to communicate with the network. If you are in a hurry to use, 30 seconds of waiting is enough to make you feel very long. Let's see how we can speed up the port initialization process for the switch. Understanding the process of switch
