VRRP is a public protocol and can interwork with non-Huawei devices.

Can BFD on S series switches interwork with non-Huawei devices
BFD supported by S series switches (except S1700 switches) complies with the standard protocol, so they can interwork with other BFD-supported devices. Note that you need to configure the same intervals for sending and receiving BFD packets on the local and peer devices.

Precautions for STP interworking on an S series switch
S (except the S1700) series switches adopt the standard STP/RSTP/MSTP algorithm. When a Huawei switch that runs STP interworks with a non-Huawei device, pay attention to the following: 1. If the non-Huawei device runs the standard STP algorithm, the Huawei switch can interwork properly with the device. 2. If the non-Huawei device runs a non-standard STP protocol except the Cisco Per VLAN Spanning Tree (PVST) protocol, the Huawei switch can transparently transmit STP packets from the device after the stp disable and bpdu enable commands are executed on the interface of the Huawei device connected to the non-Huawei device. 3. If the non-Huawei device is a Cisco device that runs PVST, the Huawei switch cannot negotiate with the device, but can transparently transmit packets from the device. 4. Check whether the configurations (such as the mode, root priority, and path cost) between the non-Huawei device and Huawei switch are consistent with each other. 5. Check the Proposal/Agreement mechanism. In enhanced mode, the current interface calculates the root interface when calculating the synchronization flag bit. In common mode, the interface ignores the root interface when calculating the synchronization flag bit. You can run the stp no-agreement-check command to configure the common fast transition mechanism on an interface. By default, the enhanced fast transition mechanism is configured on an interface. 6. There are two formats of MSTP BPDUs. One is dot1s, the format regulated in IEEE802.1s; the other is legacy, a private BPDU format. If the format of MSTP BDPUs is set to dotls on one interface and legacy on the peer interface, the negotiation fails. You can run the stp compliance { auto | dot1s | legacy } command to configure the specified STP BDPU format. The auto mode is set to allow an interface to automatically use the format of MSTP BDPUs sent from the remote interface. In this manner, the two interfaces use the same MSTP BDPU format. By default, MSTP BDPUs use the auto mode. 7. When a Huawei device is connected to a non-Huawei device, if the region name, revision level, and VLAN-to-instance mapping configured on the two devices are the same but the BPDU keys are different, the two devices cannot communicate with each other. To address this problem, run the stp config-digest-snoop command to enable the digest snooping function so that the BPDU keys on Huawei and non-Huawei devices are consistent.

Can S series switches interconnect with non-Huawei devices to set up a VRRP group
S600-E series switches do not support VRRP. VRRP supported by S series switches (S1700 excluded) comply with the standard protocol, so these switches can interconnect with other devices that comply with the VRRP standard protocol.

Can a Huawei STP switch work with a non-Huawei STP device
Huawei switches use the standard STP protocol. Whether a switch can work with a non-Huawei STP device depends on the protocol running on the non-Huawei device: If the non-Huawei device runs a standard STP protocol, including STP, MSTP, and RSTP, the Huawei switch can work with it. If the non-Huawei device runs a non-standard STP protocol, except for the Cisco Per VLAN Spanning Tree (PVST) protocol, the Huawei switch can transparently transmit the STP packets from the device after you run the stp disable and bpdu enable commands on the interface connected to the non-Huawei device. If the non-Huawei device is a Cisco device that runs PVST, the switch cannot negotiate with the device, but can transparently transmit the packets from the device.

Can S series modular switches set up a cluster with non-Huawei devices
S series modular switches cannot create a cluster with non-Huawei devices. For S series modular switches, only devices of the same series can create a cluster. For example, a cluster can be established between S7706 and S7712, S9706 and S9712, S12708 and S12712, and S9306 and S9312. However, switches of different series, for example, S7706 and S9706, cannot set up a cluster.
