I’m a little unclear as to how you configured the nodes I have basically use a single NIC (some are LACP bonds) with a GENERAL link type (not TRUNK or ACCESS) where there is a default VLAN (which I don’t tag) and the rest of the VLANs are tagged. On my switch (TP-LINK) I have to go to the VLANs and say TAG on all of them except the DEFAULT one. I couldn’t get TRUNK working even with one untagged and the rest tagged. For me, using GENERAL was the way I did it.<div class=""><br class=""></div><div class="">I’m not a networking except on hardware but this discussion may clarify. I have no idea why TRUNK didn’t work over GENERAL and didn’t spend much more time than that but here’s a discussion on the topic <a href="https://supportforums.cisco.com/discussion/11897946/general-vs-trunk-mode" class="">https://supportforums.cisco.com/discussion/11897946/general-vs-trunk-mode</a></div><div class=""><br class=""></div><div class="">Tom<br class="">

It used to be an untagged network and it worked fine, but I needed to add more networks on the host. The switch it is connected to has the port configured as a trunk port with these VLANs. When a VM sends traffic out (to get a DHCP address for instance), it reaches the server but does not get the DHCP offer that the server sends. I did a tcpdump on the node that hosts the VM and the packets going out do not have a VLAN tag. I assume the VM host interface would should not have the tag present, but that the p2p1.91 interface should put the VLAN tag on.<br class=""><br class="">The relevant interface configuration on the node that the VM host is on looks like:<br class=""><br class="">27: sohonet_DMZ: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP <br class=""> link/ether a0:36:9f:2a:63:20 brd ff:ff:ff:ff:ff:ff<br class="">29: p2p1.91@p2p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue master vmnet state UP <br class=""> link/ether a0:36:9f:2a:63:20 brd ff:ff:ff:ff:ff:ff<br class="">30: vmnet: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP <br class=""> link/ether a0:36:9f:2a:63:20 brd ff:ff:ff:ff:ff:ff<br class=""> inet6 fe80::a236:9fff:fe2a:6320/64 scope link <br class=""> valid_lft forever preferred_lft forever<br class="">31: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vmnet state UNKNOWN qlen 500<br class=""> link/ether fe:1a:4a:16:01:58 brd ff:ff:ff:ff:ff:ff<br class=""> inet6 fe80::fc1a:4aff:fe16:158/64 scope link <br class=""> valid_lft forever preferred_lft forever<br class="">32: vnet1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vmnet state UNKNOWN qlen 500<br class=""> link/ether fe:1a:4a:16:01:5c brd ff:ff:ff:ff:ff:ff<br class=""> inet6 fe80::fc1a:4aff:fe16:15c/64 scope link <br class=""> valid_lft forever preferred_lft forever<br class=""><br class=""></div>where vnet1 is the VM interface, and p2p1.91 is the VLAN'd interface for the network.
