LACP between Cisco and Huawei

[m.pederneschi]

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?

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.

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.
