You need to have a vlan capable switch/machine connected and properly configured... If you plug in the machine to a normal switch, and the other machine isn't vlan aware not much will happen... Now if you configure your machine to route (net.inet.ip.forwarding) and setup the pc w/ the proper routing tables, you'll be able to ping the machines... If this doesn't help, please talk w/ a local network engineer to help you configure your network properly... I'm succussfully using FreeBSD with both vlans, and aliases (multiple ips on a single interface aka broadcast domain)... > On Tue, Mar 12, 2013 at 5:06 PM, Ian FREISLICH <ianf@clue.co.za> wrote: > > > Yasir hussan wrote: > > > Thanks for notic but all the elebration was for make alias on one > > > interface but i want to have multiple interface, i can no where that > > > some one would have tring to creating new interfaces and using them, > > > or may be i am missing something, just send its solution if have, > > > solution should be for > > > > I still think you're confusing Linux semantics with FreeBSD semantics. > > > > On linux you would have: > > eth0 Link encap:Ethernet HWaddr 00:1E:C9:53:0B:61 > > inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0 > > inet6 addr: fe80::21e:c9ff:fe53:b61/64 Scope:Link > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:211328068 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:368394006 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:34065846811 (31.7 GiB) TX bytes:476377525764 (443.6 > > GiB) > > Interrupt:169 Memory:e6000000-e6011100 > > > > eth0:1 Link encap:Ethernet HWaddr 00:1E:C9:53:0B:61 > > inet addr:10.0.1.1 Bcast:10.0.1.255 Mask:255.255.255.0 > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > Interrupt:169 Memory:e6000000-e6011100 > > > > > > On FreeBSD you would have: > > > > re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 > > > > options=8209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE> > > ether 54:04:a6:96:0c:1e > > inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255 > > inet 10.0.1.1 netmask 0xffffff00 broadcast 10.0.1.255 > > media: Ethernet autoselect (1000baseT <full-duplex>) > > status: active > > > > These are both the same thing.
