port-channel

Port-channel note

We have the following setup of a port-channel between to Catalyst 3750s - SW1 Gi0/1 and Gi0/2, bundled in a port-channel are connected to Gi0/1 and Gi0/2 on SW2:

port-channel: sample topology

SW1:

interface GigabitEthernet1/0/1
description Member of PC1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,3,4
switchport mode trunk
switchport nonegotiate
channel-group 1 mode on

interface GigabitEthernet1/0/2
description Member of PC1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,3,4
switchport mode trunk
switchport nonegotiate
channel-group 1 mode on

interface Port-channel1
description to SW2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,3,4
switchport mode trunk
switchport nonegotiate

SW2:

interface GigabitEthernet1/0/1
description Member of PC1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,3,4
switchport mode trunk
switchport nonegotiate
channel-group 1 mode on

interface GigabitEthernet1/0/2
description Member of PC1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,2,3,4

interface Port-channel1

In order for the port-channel to form successfully, all port members need to have identical: › Continue reading
