Are you worried about the port mode of the switch? below, I will walk into the switch with you and hold the switch port mode completely. I will use an article with a picture and truth to make you no longer confused. Yigu Switch 1.

three-layer switch port, meaning that the limit is three layer switch port uplink and downlink traffic control, similarly, if the three-layer switch port is not connected to the PC, but a two-layer
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
Mirror Port simply, the flow of one (several) port (source port) of the switch is completely copied, from another port (destination port), so that the network administrator from the destination
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! First, the concept of po
The port of the core switch is mainly a fiber type, but the price of the switch fibre port is very expensive and requires special attention from the user, while the fibre port of the switch is not stacked and can only be used for
How to Use H3C Huawei switches: about port and VLAN technology, this article describes QoS, VLAN technology, and switch port speed limit, port configuration, etc, the author gives a comprehensive introduction to all the relevant knowledge about how to use H3C Huawei switches. H3C Huawei
packet .. when the vlan id is different from the default vlan id, you can use the command port hybrid vlan-id-list {tagged | untagged} to configure whether the port carries a Tag. Note: local Hybrid port or Trunk Port The default vlan id of the port must be the same as the
Generally, the simplest and most common way to achieve isolation between switch ports is to divide VLAN (Virtual LAN ). However, in specific applications, it is often hoped that some valns can communicate with each other flexibly after port isolation. Generally, L2 switches need to be isolated, and then VLAN mutual access is achieved on the uplinked L3 switches or routers. In fact, only layer-2 switches can
The Switch Port Analyzer (Switchedportanalyzer) is primarily designed to provide network data flow to some network analyzer. Switch Port Analyzer It can either implement several source ports in one VLAN to mirror data to a monitoring port, or mirror data from s
port is VLAN 1 when the port receives a message without VLAN tag, the message is forwarded to the port that belongs to the default VLAN (if the port's default VLAN ID is set). When the port sends a message with VLAN tag, if the VLAN ID of the message is the same as the default VLAN ID of the

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
