I am using 8021q vlans on my servers, and I cannot figure out how to make PXE/DHCP work. Has anyone figured out how to do this ?

...tdev=eth0 /etc/xen/script/network-bridge start netdev=eth0.100 /etc/xen/script/network-bridge start netdev=eth0.101 Then we use brctl show, we can see eth0.100 and eth0.101 bridges is start up. Then we start 4 xenU, 2 xenUs on each bridges. But questions is that: I can''t get the 8021q packages with ethereal tool. I doubt that I don''t setup the vlans successfully. And xenU in the vlans can''t connect the outside by using ping address. Is anybody know about this? Best Regards --Li -- Best regards --Li _______________________________________________ Xen-use...

Thank you everyone. OK, the mystery deepens, I guess. The machine does need to support several VLAN's, it is currently on a trunkport (8021q encapsulated), it made it into the ARP table - which I specifically tested for by physically unplugging the table, clearing the ARP table and plugging it back in. The ARP table currently looks like this: hq#show arp Protocol Address Age (min) Hardware Addr Type Interface Internet...

...strip the tag out". You can either terminate the VLAN at the switch port (untagged) which will strip out the VLAN tag or you can pass the packet containing the VLAN tag to the computer or other device(tagged/trunk). This device can then pull out the tag. On linux this mechanism is done by an 8021q VLAN interface.

Hi, has anybody a running setup with 2 or more tinc daemons in switch mode which transport 8021q tagged traffic? I am trying to connect two segments with about 4 x 1000 mac addresses (distributed on different vlans). I am always running out of memory on one side. This happens only on the side where the arp requests come from. Currently there is no unicast traffic between the sides; only broa...

Appologies. - checkpatches.pl errors fixed Changes since v2: - Added inline functiosn to manimulate vlan hw filters and re-use in 8021q and bridge code. - Use rtnl_dereference (Michael Tsirkin) - Remove synchronize_net() call (Eric Dumazet) - Fix NULL ptr deref bug I introduced in br_ifinfo_notify.

...deadlock has happened. Also you can list the currently held locks (if CONFIG_LOCKDEP is enabled) via magic sysrq + d for example. See which process is holding them, what are their priorities and so on. Try to build some theory of how a deadlock might happen and then go about proving it. Does the 8021q module have the same problem? It uses similar code to set its hook. > Please let me know whether you have any thoughts on how the above > issues were triggered, and what other information I could gather to > further demystify this bug.

Hello all, I am trying to make a little bit more complex QoS/Shapping form and I need to shape a PPPoE conection that I serve to my clients. So this is the scope: client connects using pppoe so it gets an IP address (from pppoe pool) and open an interface into my linux box interface for this client is ppp0 client has got an ip 1.1.1.2/32 and it is poiting to pppoe-server 1.1.1.1 So,
