Linux 8021Q trunk to 3550 trunk port: VMWARE vlan problems
Here is my network information. I have a Cisco 3550 Running the latest iOS. I have a linux server with 1 ethernet card in it.
I am running GNS3 inside of a vmware version of Ubuntu.
The 3550 port my linux server is connected to is fa0/2
eth0 on my linux box.
I have two vlans created on my 3550,
vlan 10 subnet: 192.168.2.0/24
vlan 20 subnet: 192.168.3.0/24
I made dhcp pools for both vlans on the 3550
Even though for this server vlan 10 it uses a static ip which has been excluded from the dhcp pool
On linux I ran modprobe 8021q, setup the interfaces, so now eth0 has no ip address.
eth0.10 has a static ip of 192.168.2.20
eth0.20 has a dhcp ip of 192.168.3.2
the 3550 gateways
vlan10 : 192.168.2.10
I can ping both gateways, computers on the network, and the internet.
I can also ping back from any device on my network to both ip address on my linux server.
Now the problem arises because I am broke and cannot afford more ethernet cards.
I am trying to bridge vmware's traffic through the same eth0 device, but it is not connected to anything.
That is the first problem:
Routing traffic from vmware as bridged through my linux server which is connected to a trunk on the switch through one network card.
(I am willing to change the setup if someone has a better suggestion, but I was pretty proud of myself so far)
The other problem is I want to route GNS3 routers through the same interface to the switch, this is another reason I wanted it to be a trunk, so I could route multiple vlans out of the GNS3 routers, through my linux server, into the trunk port on my switch and into the rest of my network, and back in again.
Has anybody delt with this problem before? I have searched for answers to this vmware / linux 8021Q and I could not find any answers or advice.
Starting from NFVIS 3.12 versions, the deploy option does not depict all the SR-IOV VFs(Virtual Functions) available in a physical interface. This change is introduced as (i) the number of VFs of ENCS platform on LANs side is increased to 24 and (ii) the...

Hi alli have 40 spots (40 Ethernet cables for computers coming out from switch) and i want each of these spots to have fix IP which means if i swap the computer the IP of certain spot remain the same.example : at spot 30 i have IP address of 192.168.22.40...
