trunking between Huawei S3900 and Cisco catalyst 3750

One of my edge Huawei S3900 stack switches is dead, I am going to replace it with a Cisco switch Catalyst 3750 series PoE-48 via a trunk link with GE fiber port on both ends, please see the diagram below.
trunk trunk
Core switchrouter<----------S3900<--------------->Cisco Catlyst 3750

I haven’t touch Cisco switch for many years, I would like to ask the following questions:

1.)      Do I need to take any precaution before connecting this Cisco switch into my Huawei network? Only one link between S3900 and C3750, so I don't need worry anout STP? Do I need to worry about Default vlan regarding trunking port?
2.)      I need to use different trucking protocol e.g. 802.1Q etc to interconnect these two switches (S3900 and Catalyst 3750), please see the following configuration:

For C3750:

switchport trunk encapsulation dot1q
switchport trunk native vlan (What you want)
switchport trunk allowed vlan (VLANs required)
switchport mode trunk
spanning-tree portfast trunk

For S3900:

port link-type trunk
port trunk permit vlan all

Do you think the configurations above are right?

Do I need to manually enter Duplex and speed options ?

3.)If the configurations are not right, then what are the commands for trucking port/link should I use on the Cisco switch (it uses IOS software) and Huawei switch? Procedures of the commands would be really helpful !

Any information and help would be much appreciated.

Thanks

Regards

being a trunk like, I would manually set port speed and duplex. I do that for all network devices. Also, looks like you are allowing all vlans so you can eliminate the sw tr al vl xxx command as without this command, it will trunk all VLANS. As for native VLAN, you can leave this blank and it will trunk VLAN 1 natively by default. Not sure what VLAN S3900 uses. However, you can connect the 3750 to the S3900 and run term mon on a telnet/ssh session (or is consoled, you don't need this command to see session output), and you will see if the native vlan matches or not and adjust from there. I would also disable DTP (Dynamic Trunking Protocol) as well. Other than that, its pretty simple.

Hi SeeMeShakinMyHead,

Thanks for youe help it's appreciated.
I got it wirking by using the following:

For Cisco catalyst 3750 :
interface GigabitEthernet1/0/1
switchport trunk encapsulation dot1q
switchport mode trunk
spanning-tree portfast trunk

For Huawei S3900:
interface GigabitEthernet1/1/1
port link-type trunk
port trunk permit vlan all

Also I make sure the new Cisco switch is not going to competing for root switch when it is in our live network, so I did the following on this cisco switch:
Switch(config)#spanning-tree mst 1-4094 priority 61440

Now I have another question: what are the configurations/commands to configure port of Cisco Catalyst 3750 for VoIP (equivalent to the configurations on the port on Huawei S3900):

For S3900:
interface Ethernet1/0/2
poe enable
port link-type hybrid
port hybrid vlan 8 tagged
port hybrid vlan 100 untagged
undo port hybrid vlan 1
port hybrid pvid vlan 100
priority trust

* vlan 8 is for VoIP, vlan 100 is for staff PCs/laptops, Vlan1 is default vlan

What are the equivalent commands on port of Cisco catalyst 3750 for VoIP and PCs?

Any information and help would be much appreciated.

Thanks

put this on the interface. The switch will automatically configure QoS queues, policy-maps and class-maps for this.

mls qos trust device cisco-phone
mls qos trust cos
auto qos voip cisco-phone

what "the interface" ? uplink interface? or the interface the VoIP phone is going to be connected to?

Also, I use Alcatel VoIP (IP Touch 4018) instead of Cisco VoIP phone, do I still need to use "mls qos trust device cisco-phone" or "auto qos voip cisco-phone" ?

I configured "auto qos voip trust" only on both interfaces by following:

Thanks for youe advice, Now Cisco is connected to Huawei switch.

Wireless, VoIP and Data are working.
