Why Would a Layer 2 Switch Need an Ip Address

Port 102 is a layer 3 port 1921682253 255255255248. However to perform switch management over the network or use protocols such as SNMP the switch will need to have an IP address.

The difference between TCP Transmission Control Protocol and IP Internet Protocol is their role in the data transmission process.

. The ip helper command was put on each SVI in the switch. MAC addresses are typically used only to direct packets from one device to the next device as data travels on a network. They break up one large collision domain into multiple smaller ones.

Layer 3 switch or multilayer switch can do all the job of a layer 2 switch and additional static routing and dynamic routing as well. The IP address is configured under a logical interface known as the management domain or VLAN. Layer 2 switching or Data Link layer switching is the process of using devices MAC addresses to decide where to forward framesSwitches and bridges are used for Layer 2 switching.

Together the two form the TCPIP protocol suite. Port 103 trunk port that the SVI connect through to another device. IP obtains the address where data is sent your computer has an IP address.

MAC operates at Layer 2 of the OSI model while IP operates at Layer 3. Usually the default VLAN 1 acts like the switchs own NIC for connecting into a LAN to send IP packets. TCP ensures accurate data delivery once that IP address has been found.

All of my connections to the switch are as follows. In a typical LAN all hosts are connected to one central device. The connection on the switch to the router is a layer 3 connection with an IP of 1921682253 255255255248.

That means that the MAC address of your computers network adapter travels the network only until the next device along the way. That means a Layer 3 switch has both MAC address table and IP routing table and handles intra-VLAN communication and packets routing between different VLANs.
