etherchannel

[Feker Miri]

Hi,

I have a problem with etherchannel in WS-C3650 :

In my LAN network, I have two C3650 in stackwise mode for Core and three C3650 in stackwise mode for access modul, when I apply a etherchannel configuration I see this error :

Apr 27 12:32:04.014: %EC-5-L3DONTBNDL2: Gi1/1/1 suspended: LACP currently not enabled on the remote port.

*Apr 27 12:32:51.374: %LINK-3-UPDOWN: Interface GigabitEthernet2/1/1, changed state to up

*Apr 27 12:32:57.076: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/1/1, changed state to up

*Apr 27 12:32:58.065: %LINK-3-UPDOWN: Interface Port-channel1, changed state to up

*Apr 27 12:32:59.065: %LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1, changed state to up

This is a configuration Core Switch :

interface Port-channel1

switchport trunk native vlan 18

switchport mode trunk

!

interface GigabitEthernet1/1/1

description ## PO TO Grn_floor ##

switchport trunk native vlan 18

switchport mode trunk

channel-group 1 mode active

!

interface GigabitEthernet2/1/1

description ## PO TO Grn_floor ##

switchport trunk native vlan 18

switchport mode trunk

channel-group 1 mode active

This is a configuration in access switch:

interface Port-channel1

switchport trunk native vlan 18

switchport mode trunk

!

interface GigabitEthernet1/1/1

switchport trunk native vlan 18

switchport mode trunk

channel-group 1 mode active

end

!

interface GigabitEthernet1/1/2

switchport trunk native vlan 18

switchport mode trunk

channel-group 1 mode active

 all Switch have same IOS-XE :cat3k_caa-universalk9.SPA.03.06.04.E.152-2.E4.bin

Can you help me

Hi,

What's the output for the "show etherchannel summary "  command?

if you see "Po1(SU)" in output, everything should be fine and just ignore the error message. Maybe it's related to negotiation between ports. Otherwise, please share the output of the above command.

thx to your replay

no 

this is a outpout for the " sh etherchannel summary"

SWSCF-ACC4-GF3650#sh etherchannel summary
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator

M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
d - default port

Number of channel-groups in use: 1
Number of aggregators: 1

This "Gi1/1/2(s)" shows the port  is suspended. The reason maybe incompatibility between speed, duplex, .... on the interfaces. Try "show int " in all members and check the interface configuration.

Try a Shut and No Shut on each port and on the Port Channel interface.

If not, try a switch reboot.

The config looks ok.
