Configuring EtherChannels
Before You Begin
Ensure that you have enabled the LACP feature.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# interface type slot/port
3. switch(config-if)# channel-group channel-number [force] [mode {on | active | passive}]
4. switch(config-if)# no channel-group number mode
DETAILED STEPS
Command or Action
Step 1 switch# configure terminal
Step 2 switch(config)# interface type
slot/port
Step 3 switch(config-if)# channel-group
channel-number [force] [mode {on
| active | passive}]
Step 4 switch(config-if)# no
channel-group number mode
This example shows how to set the LACP-enabled interface to active port-channel mode for Ethernet interface
1/4 in channel group 5:
switch# configure terminal
switch (config)# interface ethernet 1/4
switch(config-if)# channel-group 5 mode active
Purpose
Enters configuration mode.
Specifies the interface to configure, and enters the interface configuration mode.
Specifies the port mode for the link in an EtherChannel. After LACP is enabled,
you configure each link or the entire channel as active or passive.
force—Specifies that the LAN port be forcefully added to the channel group. This
option is available in Cisco NX-OS Release 5.0(2)N2(1).
mode—Specifies the EtherChannel mode of the interface.
active—Specifies that when you enable LACP, this command enables LACP on
the specified interface. The interface is in an active negotiating state in which the
port initiates negotiations with other ports by sending LACP packets.
on—(Default mode) Specifies that all EtherChannels that are not running LACP
remain in this mode.
passive—Enables LACP only if an LACP device is detected. The interface is in a
passive negotiation state in which the port responds to LACP packets that it receives
but does not initiate LACP negotiation.
When you run EtherChannels with no associated protocol, the channel mode is
always on.
Returns the port mode to on for the specified interface.
