The port in active mode negotiates with the other side to form Etherchannel while the interface in passive mode indicates using LACP, but responds to requests only and does not send any request.

A port in the passive mode cannot form an EtherChannel with another port that is also in the passive mode because neither port starts LACP negotiation.

A port in the active mode can form an EtherChannel with another port that is in the active or passive mode. It is a method used by routers/switches to automatically establish link aggregation.

Switch/Router Ports can form an EtherChannel when they are in different LACP modes as per the below criteria вЂ“ LACPВ is an open standard protocol and published under the 802.3ad specification. These are the final settings I used for both.

Use the interface range command to configure more than one interface at a time.

However, donвЂ™t forget to have the same interface settings on all ports. Just add the channel-group command on all relevant physical interfaces. Related вЂ“ PORT Channel vs EtherChannel LACP (LINK AGGREGATION CONTROL PROTOCOL) The configuration of the Cisco switch is quite simple. Note вЂ“ Switch1 is configured under desirableВ mode while Switch2 under AutoВ mode to negotiate and form EtherChannel Switch2(config-if-range)#interface port-channel 1

Trunk links are required between devices in any situation where traffic from multiple VLANs will traverse the link. The syntax of the command is as follows: Switch(config-if) switchport mode trunk. Switch2(config)#interface range Gi0/0-3Switch2(config-if-range)#channel-group 1 mode auto The switchport mode trunk command is used on the Cisco Catalyst 2950 switch to configure a port as a VLAN trunk port. PAgP Mode negotiation вЂ“ PAgP ModeД®therChannel Configuration between Switch1 and Switch2 using PAgPВ is shown below вЂ“ The port in autoВ mode defines using PAgP butВ does not send requests. The port in desirableВ mode is one which sends requests to the other side to see if it is also using PAgP.

A port in the auto mode can form an EtherChannel with another port in the desirable mode.

A port in the desirable mode can form an EtherChannel with another port that is in the desirable or auto mode.

Switch/RouterВ Ports can form an EtherChannel when they are in different PAgP modes as per below criteria вЂ“ It uses the multicast address of 01-00-0C-CC-CC-CCВ for communication. PAgPВ is Cisco proprietary Etherchannel technology.

802.1Q trunking is configured in the on mode between Access1 and Distribution1 switches. Feature Example In this example the switches Access1 and Distribution1 and Core1 are connected as shown in Figure 6-2.

EtherChannel configuration can be in one of below enlisted 3 modes- Etherchannel ModeДЇorced to form Etherchannel without using negotiation protocolД«elow diagram will be referred to while forming and configuring EtherChannel in вЂ“ The commands show interfaces trunk and show interface mod interfaceid trunk are not available on all switches that run IOS. We can create an EtherChannel on a standalone switch, on a single switch in the stack, or on multiple switches in the stack (known as cross-stack EtherChannel).
