I have two 3750G-24PS switches and three Huawei S2300 switches. I have configured VLANs (15 nos.) in 3750. Is it possible for me to use those three switches for all VLANs or do I have to use separate switches for each VLAN? ... View more

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 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 S5700: 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. ... View more
