EtherChannel is a port link aggregation technology in which many physical port links are classified into one logical link. Has the capability to rush many Ethernet lines into one virtual line on Cisco bias. It’s used to give high-speed links and redundancy. A maximum of 8 links can be added up to form a single logical link. Generally use this to increase the bandwidth of Subcaste 2 technologies.

To learn more about EtherChannel and its configuration refer to  EtherChannel in the Computer Network article.

Steps to Configure and Verify Layer3 EtherChannel:

Step 1: First open the cisco packet tracer desktop and create a network topology of the devices given below:

S.NO Device Model Name
1. Switch 3650-24PC
2. Cable Automatic connecting cable

 

Step 2: Configure Switches with Etherchannel and IP addresses.

S.NO device IP Address Subnet Mask
1. 3650-24PS Multilayer switch0 192.168.10.1 255.255.255.0
2. 3650-24PS Multilayer switch1 192.168.10.2 255.255.255.0
  • Click on multilayer switch0 and go to CLI.
  • Then, type these commands to configure EtherChannel 
Switch>en
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#int range Gig1/0/1-2
Switch(config-if-range)#no switchport
Switch(config-if-range)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet1/0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet1/0/1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet1/0/2, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet1/0/2, changed state to up
Switch(config-if-range)#int port-channel 1
Switch(config-if)#int port-channel 1
Switch(config-if)#no switchport
Switch(config-if)#exit
Switch(config)#int range Gig1/0/1-2

Switch(config-if-range)#channel-group 1 mode ?
active Enable LACP unconditionally
auto Enable PAgP only if a PAgP device is detected
desirable Enable PAgP unconditionally
on Enable Etherchannel only
passive Enable LACP only if a LACP device is detected

Switch(config-if-range)#channel-group 1 mode on
Switch(config-if-range)#
%LINK-5-CHANGED: Interface Port-channel1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface
Port-channel1, changed state to up

Switch(config-if-range)#no switchport
Switch(config-if-range)#exit
Switch(config)#interface port-channel 1

Switch(config-if)#ip add 192.168.10.1 255.255.255.0
Switch(config-if)#

Step 3: Click on switch1 and follow the same procedure as switch0.

Switch>en
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#int range Gig1/0/1-2
Switch(config-if-range)#no switchport
Switch(config-if-range)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet1/0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface

%LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet1/0/2, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface
GigabitEthernet1/0/2, changed state to up
Switch(config-if-range)#exit
Switch(config)#interface port-channel 1
Switch(config-if)#no switchport
Switch(config-if)#exit
Switch(config)#int range Gig1/0/1-2
Switch(config-if-range)#channel-group 1 mode on
Switch(config-if-range)#
%LINK-5-CHANGED: Interface Port-channel1, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1,
changed state to up
Switch(config-if-range)#exit
Switch(config)#in port-channel 1
Switch(config-if)#ip add 192.168.10.2 255.255.255.0
Switch(config-if)#

Step 4: Verify the EtherChannel summary and connection.

Step 5: Checking the IP address of Port-channel 1 in multilayer switch0:

 

  • Checking the IP address of Port-channel 1 in multilayer switch0:
