Static EtherChannel

Unlike PAgP or LACP, Static EtherChannel does not require any negotiation between switches.

Figure 1 – Static EtherChannel with Mode On

Interfaces are statically grouped using the on mode at both ends. This configuration will also include setting up interfaces as trunks and allowing VLAN 50 on the trunk.

Prerequisites for Configuration

Before starting, ensure the following conditions are met:

• Interface Consistency: All interfaces in the EtherChannel must have the same speed, duplex, and interface type.

• VLAN and Trunking: For Layer 2 links, interfaces must be in the same VLAN or have identical trunk settings.

• Active Links: Ensure that each physical link is operational.

Figure 2 – EtherChannel Requirements Before Configuration

We will configure Static EtherChannel by activating on mode, configuring interfaces as trunks, and allowing VLAN 50 on the trunk for demonstration purposes.

Enter Interface Configuration Mode

Select the interfaces that will form the EtherChannel on each switch.

• On SW1:

SW1(config)# interface range g0/0 - 1

• On SW2:

SW2(config)# interface range g0/0 - 1

🔹 Set Static EtherChannel Mode

The on mode creates an EtherChannel without any negotiation protocol. This means both switches must be manually configured for EtherChannel to work. Configure it on both switches:

• SW1:

SW1(config-if-range)# channel-group 1 mode on

• SW2:

SW2(config-if-range)# channel-group 1 mode on

After this command is applied, a logical interface called Port-Channel 1 (Po1) is created on each switch !

Configure Trunk Mode and VLAN

For this example, Port-Channel 1 must be configured as a trunk, using 802.1q encapsulation, and allowing VLAN 50 for traffic.
