Trunk problem

Latest reply: Apr 20, 2020 20:56:47 3112 4 0 0
One of my edge Huawei S5700-28C-EI 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<----------S5700<--------------->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 S5700 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 (S5700 and Catalyst 3750), please see the following configuration:

For S5700:

 port link-type trunk
 port trunk permit vlan all

For WS-C3750X-24T-L:

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

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.
