Switch2(config-if-range)#interface port-channel 2 Switch2(config-if-range)#channel-group 2 mode desirable Switch2 Configuration: Switch1(config)#interface range FastEthernet 0/1 - 2

Switch1(config-if-range)#interface port-channel 1

Switch1(config-if-range)#channel-group 1 mode desirable Switch1 Configuration: Switch1(config)#interface range FastEthernet 0/1 - 2 We have two Layer 3 switches, Switch1 and Switch2, and we will configure the two links connecting them as EtherChannels. We have to issue the ‘no switchport’ command to make the physical interface a routed port/interface (Group state = from Layer 2 to Layer 3)įor the Layer 3 Etherchannel configuration, we will use the topology below as an example. The port-channel interface number can differ between two neighbor Layer 3 Switches, but we have to use the same Channel Group Number for all physical interfaces on a Layer 3 Switch.Ģ. Owing to its features, the layer 3 switches can single handedly manage the traffic controlling and routing in LANs utilizing bandwidth hungry devices.1. This configuration enables it to manage the VLAN routing at the local level and optimizes the work efficiency of router enabling it to perform long distance data transmission. In such networks, each individual switch is configured with a main router. Layer 3 switches are used in several high density WANs comprising overloaded routers. They can support bandwidth-hungry end-user applications and resources.

This flexibility makes them an ideal choice for the fast-growing enterprises, where high speed networks are implemented. When used in combination with layer 2 switches, these switches can accommodate any number of users, and help reduce the need for increasing bandwidth or adding extra layer 3 switches or making any additional investments.

These switches are commonly used in the fast growing campuses, organizations, as well as data centers, where high density networking is involved. More Buying Choices 1,072.
