But I cannot add any port neither to vlan 300 nor to vlan 303!
sw4# conf t
sw4(config)# int eth e2
sw4(config-if)# switchport mode access
sw4(config-if)# switchport access vlan 300
VLAN 300: VLAN was not created by user.
My conclusion: the realization of GVRP in LinkSys switches is completely weird and broken. And now I really don't know what to do with ~45 LinkSys SPS224G4 switches in my network. You know, creating one VLAN on them by hands is somewhat difficult, isn't it?
Is there anything able to change my mind? Thanks in advance!
I dont have any linksys switches in my network as of now but once upon a time i had Cabletron with GVRP which messed up my network when connected with Cisco switches with redundant links.
Can you please post the config of switches on which you are trying your hand, coz i can see that you have configured all ports on SW4 as trunk in first post and than you are trying to configure it as access.
Also confirm the mode you are running for GVRP ? make sure links between switches are 802.1q trunk.
