Try this lines for
create three VLANs
[*]name the three VLANs
[*]bind the three VLANs to 3 three separate Ports, so you connect a device without VLAN-Support
[*]bind all three VLANs to Port 4 to connect a device, which support VLANs

You have to do this in configure mode.

Good luck

Hi Ulf,

thank you for your input.

I have actually done these steps already in config mode. Based on the description from VMware, after configuring these steps, the following two CISCO commands should be also entered:

- switchport trunk encapsulation dot1q

- spanning-tree portfast trunk

My "problem" is to find/understand the equivalent commands for the TL-SG5428 switch. I read the CLI manual, but I am not sure which TL-SG5428 config-commands would do the same as these previous two commands for CISCO switches. Any idea?

Regards,
Steve

Hi Steve,

"switchport mode trunk" on the TP-Link is the same like "switchport trunk encapsulation dot1q" on CISCO. Perhaps Cisco can also port pased vlans.

For spanning tree I set this one time in the global configuration mode and on every interface, which could be affected:

[CODE]
#...snip
#
ip ssh server
no ip ssh version v1
#
#
spanning-tree
#
snmp-server
#...snip
ip ssh server
no ip ssh version v1
#
#
spanning-tree
#
snmp-server
#
#...snip
#
interface gigabitEthernet 1/0/3
description "Trunk SW001"
switchport mode trunk
switchport trunk allowed vlan 10,20,30,40,50,60,70,21,41
switchport trunk allowed vlan 30
switchport pvid 10
spanning-tree

#
interface gigabitEthernet 1/0/4
description "Trunk SW001"
switchport mode trunk
switchport trunk allowed vlan 10,20,30,40,50,60,70,21,41
switchport trunk allowed vlan 30
switchport pvid 10
spanning-tree

#
#...snip
[/CODE]

This this configuration there is noch network storm anymore between this two switches.

Good luck.
Ulf
