Trunk-Trunk Configuration Between Huawei & Cisco

[erudes1991]

Hi everyone,

Has anyone experienced switch configuration between Cisco and Huawei?

Im trying to set up trunk to trunk, and I had luck with only one port, the others I have just don’t work.

What type of encapsulation do I need in order for these two to work?

What’s the native default VLAN configuration for each of the trunks, on both brands that I need to use?

If you could post the configs, it would help us see what you’re dealing with.

You want to use 802.1q trunking, but that will be the default on pretty much all modern switches. Native VLAN is mostly a Cisco concept. On the Huawei they will likely use the terms “tagged” and “untagged”. The default native VLAN on a Cisco switch is VLAN 1; this just means that frames on VLAN 1 are sent across the trunk “untagged”. So on the Huawei side, just leave VLAN 1 untagged on the trunk port and tag all the other VLANs you need the trunk to carry.

Sorry for late reply,

That definitely did the trick.

I allowed VLANs through specifically on both trunks​, and not all by default.

I understand the default VLAN concept, but why would that make a difference?

Thanks!
