Working Principle – Layer 3 switch looks at the MAC address of the destination host and sends the frame only to that recipient. Moreover, routers were devices that connected the LAN to the WAN and switches were just LAN devices.
Switch(config)interface FastEthernet 0/1 Switch(config-if)no switchport Switch(config-if)ip address 10.1.1.1 255.255.255. In this case, it is FastEthernet 0/1 for the Cisco Catalyst 3550. While a router have more options like SDH, SONET, E1/T1 etc. Step 5: IP configuration facing the default router should look like the commands below. Interfaces - Another difference regarding a layer 3 switch vs router is that a Layer 3 switch is limited in interfaces it supported (usually just Ethernet for RJ45 and single mode/multimode fiber). For many, the command line belongs to long gone days: when computers were controlled by typing mystical commands into a black window when the mouse possessed no power. Enter configure terminal to go to Global Configuration Mode. In this STP (Spanning Tree Protocol) Configuration Example, we will configure STP on Cisco switches on Cisco Packet Tracer.
Switch to router configuration password#
So layer 3 switch is most used to support routing between VLANs. Log on to the router, and enter the privileged EXEC mode by entering enable and then entering the enable password command. Additionally, designed specifically for use on intranets, a layer 3 switch usually has no WAN ports and features a traditional router usually gets.
Switch to router configuration software#
The hardware inside a layer 3 switch blends that of traditional switches and routers, improving some of a router’s software logic with integrated circuit hardware to offer better performance for LANs. Hardware - The key difference between layer 3 switch vs router lies in the hardware. R2(config)router rip R2(config-router)network 192.168.12.0 We use the router rip command to go to the RIP configuration. Like traditional router, a layer 3 switch can also be configured to support routing protocols such as RIP, OSPF, and EIGRP. Layer 3 switches are thus able to segregate ports into separate VLANs and perform the routing between them. layer 3 switch enable packets switching by inspecting both their IP addresses and their MAC addresses.
Layer 3 Switch Vs Router: Similarities and DifferencesĪ layer 3 switch is both a switch and a router: it can be regarded as a router with multiple Ethernet ports and with switching function.
