Hi all,
I'm trying to configure a port-channel between a Cisco Cat 4507 and a Huawei switch; when I try to activate the Po on the Cisco side I got the following error:
*Jun 8 06:27:08.289: %PM-4-ERR_DISABLE: channel-misconfig error detected on Po20, putting Te1/1 in err-disable state
*Jun 8 06:27:08.293: %EC-5-UNBUNDLE: Interface Te1/1 left the port-channel Po20
*Jun 8 06:27:08.293: %PM-4-ERR_DISABLE: channel-misconfig error detected on Po20, putting Te1/2 in err-disable state
*Jun 8 06:27:08.305: %EC-5-UNBUNDLE: Interface Te1/2 left the port-channel Po20
*Jun 8 06:27:08.305: %PM-4-ERR_DISABLE: channel-misconfig error detected on Po20, putting Po20 in err-disable state
*Jun 8 06:27:08.297: %EC-5-UNBUNDLE: STANDBY:Interface Te1/1 left the port-channel Po20
*Jun 8 06:27:08.301: %PM-4-ERR_DISABLE: STANDBY:channel-misconfig error detected on Te1/1, putting Te1/1 in err-disable state
*Jun 8 06:27:08.325: %PM-4-ERR_DISABLE: STANDBY:channel-misconfig error detected on Te1/2, putting Te1/2 in err-disable state
*Jun 8 06:27:08.445: %PM-4-ERR_DISABLE: STANDBY:channel-misconfig error detected on Po20, putting Te1/1 in err-disable state
*Jun 8 06:27:08.445: %PM-4-ERR_DISABLE: STANDBY:channel-misconfig error detected on Po20, putting Te1/2 in err-disable state
*Jun 8 06:27:08.445: %PM-4-ERR_DISABLE: STANDBY:channel-misconfig error detected on Po20, putting Po20 in err-disable state
Below the configuration on the Cisco side:
interface Port-channel20
switchport
switchport trunk allowed vlan 1,705-707
switchport mode trunk
switchport nonegotiate
flowcontrol receive on
spanning-tree link-type point-to-point
end
interface TenGigabitEthernet1/1
switchport trunk allowed vlan 1,705-707
switchport mode trunk
switchport nonegotiate
shutdown
channel-group 20 mode active
end
interface TenGigabitEthernet1/2
switchport trunk allowed vlan 1,705-707
switchport mode trunk
switchport nonegotiate
shutdown
channel-group 20 mode active
end
and here the configuration on the Huawei Switch:
interface Eth-Trunk20
port link-type trunk
port trunk allow-pass vlan 705 to 707
stp disable
mode lacp-static
lacp timeout fast
interface 10GE1/0/3
eth-trunk 20
lacp priority 16784
device transceiver 10GBASE-COPPER
#
#
interface 10GE2/0/3
eth-trunk 20
lacp priority 32678
device transceiver 10GBASE-COPPER
Any suggetion on the cause of this error?
I need to apply the lacp priority in order to have an active/stand-by configuration.
Many thanks,
Maurizio

Hi,
Try to put the command channel-protocol lacp on the physical ports for Po20 then bounce them. If it still doesn't work, try removing the the command switchport nonegotiate.

Hi agapitca19,
thanks for your suggestion but it still doesn't work. I tried to remove on the Huawei side the lacp preempt and priority but same issue.
The port-channel goes up for some second:
*Jun 8 08:16:42.909: %EC-5-BUNDLE: Interface Te1/1 joined port-channel Po20
*Jun 8 08:16:42.997: %EC-5-BUNDLE: Interface Te1/2 joined port-channel Po20
4507-SW-1-ARM-A#
*Jun 8 08:16:42.913: %EC-5-BUNDLE: STANDBY:Interface Te1/1 joined port-channel Po20
*Jun 8 08:16:43.097: %EC-5-BUNDLE: STANDBY:Interface Te1/2 joined port-channel Po20
An then goes down.

Hi
Your config looks fine, except the physical interfaces has shutdown configured. Please check this link:

Also check the Spanning Tree configurations. Do you have Etherchannel guard configured on the Cisco device?
spanning-tree etherchannel guard misconfig

I am facing the same issue too. The problem doesn't prompts at the beginning when first connected Cisco C3560 to Huawei Switch S5720-32X-EI-AC for 4 months++, but it keep on prompting after adding and removing VLAN from VTP. Both member interfaces in the Port-Channel are being put as error-disabled, even if reset Port-Channel and Physical interfaces, it will become error-disabled again after up for certain time.

May 14 13:56:49.225 MY: %LINEPROTO-5-UPDOWN: Line protocol on Interface Port-channel1, changed state to down
Below is the solution that Huawei provided, set "undo port trunk allow-pass vlan 1" at the Huawei switch port-channel interface :
interface Eth-Trunk3
description Downlink to Cisco Switch
port link-type trunk
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan 2 to 4094
mode lacp
So far it has been running fine for a day at least. Still monitoring.
Feel free to share if anyone has another solution and information.
Found this post from Huawei website too.
