Hi,
I'm trying to setup a Port-Channel between one Cisco 4507 and one Huawei 5850. The Cisco switch is running RSPT PVST whereas the Huawei Switch is running MSTP.
Below the configuration of the Cisco:
interface Port-channel20
description *** TO HUAWEI 5720 Telecom - Link verso 5850 Lepida ***
switchport
switchport trunk native vlan 4001
switchport trunk allowed vlan 1,705-707
switchport mode trunk
flowcontrol receive on
interface TenGigabitEthernet1/1
switchport trunk native vlan 4001
switchport trunk allowed vlan 1,705-707
switchport mode trunk
channel-group 20 mode active
interface TenGigabitEthernet1/2
switchport trunk native vlan 4001
switchport trunk allowed vlan 1,705-707
switchport mode trunk
channel-group 20 mode active
And here the Huawei:
interface Eth-Trunk20
port link-type trunk
port trunk pvid vlan 4001
port trunk allow pass vlan 705 to 707
mode lacp-static
interface 10GE1/0/3
eth-trunk 20
device transceiver 10GBASE-COPPER
interface 10GE2/0/3
eth-trunk 20
device transceiver 10GBASE-COPPER
If I remove from the trunk the VLAN 1, the port-channel remain UP but on Huawei side the MSTP put the Eth-Trunk in discarding mode. If I add the VLAN 1 to the trunk the port-channel remain up for a while (I can ping side to side) but then I got the following error:

Could be a interoperability between MSTP and RSTP PVST?
Many thanks.
