Just setting the port mode hybrid and vlan stack command made it work. Thanks
Hi, I have this setup up linux labpc -> Dell switch z9100-on -> other switch The other switch / device is connnected to 1/7/1 port on Dell switch. On labpc, there is network interface for example myeth0. There is vlan interface under that e.g. myeth0.10 myeth0 and myeth0.10 has own ip address and different network. When I ping to other interface. It works perfectly fine. However, when I ping from myeth0.10, it doesn't reach 'other switch'. I have mirroring of port set up on other switch. Nothing comes. My question is that, do I need to configure the port 1/7/1 to all the ping to pass through from vlan?? I just find this vlan stuff confusing. There is trunks and vlans and private vlans, tagging and untagging. I would like to know, what is really needed. thanks for your time,              
Pinging from vlan network interface is not working
