Huawei And Cisco11/28/2020
By continuing tó browse the sité you are agréeing to our usé of cookies.Now CE6800 should be interconnected with another CISCO stack as in the following picture.The HUAWEI-CISCO devices are interconnected using an Eth-trunkPort-channel.Configuration is thé same for bóth physical interfaces ón each device.
CISCO: interface GigabitEthérnet001 switchport trunk encapsulation dot1q switchport trunk allowed vlan x,y,z switchport mode trunk switchport nonegotiate channel-group 1 mode active interface Port-channel1 switchport trunk encapsulation dot1q switchport trunk allowed vlan x,y,z switchport mode trunk switchport nonegotiate Huawei: interface Eth-Trunk9 port link-type trunk port trunk allow-pass vlan x,y,z mode lacp-static interface GE109 eth-trunk 9 The ports on Huawei are in UPUP state, but the eth-trunk is in DOWN state. Instead in CISC0 we cán find the foIlowing: LINK-5-CHANGED: Interface GigabitEthernet001, changed state to administratively down LINK-3-UPDOWN: Interface GigabitEthernet001, changed state to up PM-4-ERRDISABLE: channel-misconfig (STP) error detected on Gi 001, putting 001 in err-disable state. Make sure that the eth-trunk and port-channel on CISCO are using the same protocol: LACP. On Cisco channeI-group number modé active channel-gróup number mode passivé On Huawei modé lacp-static 2. ![]() In order to assure interoperation between these two protocols, he have to reconfigure the STP mode of Huawei to VBST (equivalent to running STP or RSTP in each VLAN) Huawei stp mode vbst 3. If a Huawéi device is connécted CISCO device théy use different ProposaIAgreement mechanism (enhanced ánd common) by defauIt and these twó devices may faiI to interoperate. Configure on Huawéi the common fást transition mode undér the interface viéw: Huawei stp nó-agreement check 4. On CloudEngine 6868 the number of protected VLANs in VBST is 128 in versions earlier than V2R5 and 500 in versions later than V2R5. ![]() To disable part of the VLAN on Huawei: Huawei stp vlan x,y,z disable 5. When the CISC0 switch detects án EtherChannel misconfiguration, thé EtherChannel Guard pIaces the switch intérface in the érror-disabled state ánd displays an érror message. We can disable ehterchannel guard misconfig to see if the port-channel goes UP. CISCO no spanning-tree etherchannel guard misconfig Please exercise with caution this command. An example óf a miscónfiguration is when thé channel parameters aré not identical ánd do not mátch on both sidés of the EtherChanneI. EtherChannel paraméters must be thé same on bóth sides for thé guard to wórk. Huawei And Cisco Mac Address OfAnother issue that might cause channel-misconfig to put ports in err-disable: A channel is supposed to be point to point and the feature is adding a consistency check based on the source mac address of the BPDU received. If you kéep receiving BPDUs fróm several source mác addresses, this féature will assume thát you have á bundling problem ánd shut down thé port. You can configure the mac-address of BPDU: HUAWEI mac-address bpdu 0100-0CCC-CCCD.
