Hello guys, 

We are replacing the cisco 2960 switch to Huawei s5720li, and when translating the cisco switch configuration to Huawei configuration, I found some configuration which I’m not sure what is the corresponding feature in Huawei.

Switch(config)#spanning-tree uplinkfast

Switch(config)#spanning-tree portfast default

 Could someone help me to figure it out?

Appreciating any suggestions, thanks.

@user_3357111 hi!

The command spanning-tree uplinkfast enables the switch to switch the root port to the backup root port when suspecting that the root port is down.

The command 'spanning-tree portfast default' enables the ports to turn to forwarding when the port turns up.

In the case of uplinkfast, it’s like the alternative port in rstp. When the root port turns to down, it turns to forwarding immediately, skipping the listening and learning state.
 
In the case of portfast, it’s like the edge port on rstp - it’s connected to the terminal devices. When the device connects to this interface, the port will skip the listening and learning state and turn to forwarding state immediately.

These two commands are commonly used on the access switch. You can use the translating tool to translate the configuration from Cisco to Huawei, please visit https://serviceturbo-cloud-cn.hu ... 3-b4b5-7a5baf2f50d1.

As @chenhui mentioned uplink-fast is backup root port and it is cisco proprietary option however Huawei have default STP option which converge the backup port by sensing if root port have failed and immediately convert alternate port to root port. Below document have very good information about it.

https://forum.huawei.com/enterprise/en/All-About-Switches-Example-for-Configuring-STP/thread/322707-861


Regarding the [#spanning-tree portfast default] above already been explained however the same config in Huawei will be as below in global.

stp edged-port default

As edged-port means listening and learning timers will be skipped so it is recommended always enable "stp bpdu-protection" in global so if anyone will connect any switch in network the port will shutdown to avoid any loop/root attempt.

It is also recommended to use "stp edged-port" in respective port(s) instead than globally and only on those port(s) which are connected by Server(s) or PC(s). To know more about where to enable edge port you can view the below document.

Thank you.

Kindest regards,
