Even thought the default is all, I would still look at making sure the Trunk has specified Vlans or all Vlans added to it. Something similar to this. console(config-if)# switchport mode trunk console(config-if)# switchport trunk allowed vlan all Or console(config-if)# switchport mode trunk console(config-if)# switchport trunk allowed vlan  add 1,200,  Something else to look into would be to setup a static route between the two switches. The following example configures a static route with prefix 172.16.0.0, prefix length 16, and gateway 131.16.1.1. Console(config)# ip route 172.16.0.0 /16 131.16.1.1 Page 212 goes over Ip route some more. support.dell.com/.../en_ug.pdf Pages to reference are 503 and page 691 support.dell.com/.../en_cli.pdf Side note, the firmware on the switches is out of date, I would recommend getting that updated. www.dell.com/.../powerconnect-5448 Keep us updated, Thanks
Hello I have a big problem with my network infrastructure. I have 16 Esxi 5.0 hosts that are connected to 2x Dell PowerConnect 5448 switches. All VM's are connected to Distributed Switches with multiple Port Groups. Every VDS Port Groups are adding VLAN ID to all frames that are sent to physical switches. VMs that are connected to the same physical switch are able to communicate but when they are connected to different switches the connection is lost :( LAG 1 is connected as  Trunk in Port Mode with GVRP disabled and admitAll frame type. Also this port is a member in: VLAN 1(Untagged System) and VLANS from 100-200 (Tagged Static) Ports that are connected to Vmware Distributed Switches are configured with General Mode,  GVRP disabled,  admitAll frame type and they are member of VLANS 100-200 (Tagged Static). Nativ VLAN: 234. Can anyone help me. Maybe im doing something wrong?  [IMAGE]
