More interfaces on GNS3 for VOSS

Miguel-Angel_RO — Sat, 24 Oct 2020 20:27:59 GMT

HI,

Does anybody know if we can use more interfaces thant the 1/1-1/8 available by default?

I changed the following:

but the interfaces are not going up when I connect them.

Thanks

Hi Miguel,

I see the same thing on the 8.2 image using GNS3 2.2.25. Let me see what I can find out.

Thanks,

Chris Thompson

Same issue, waiting for an update.

Hello,

the virtual VOSS image is based on the XA1400 (even if the name suggests otherwise), therefore there are only 8 ports available. Due to the base there are also further restrictions. For example Fabric Attach.

No matter what interface I connect to the virtual VOSS image, interface Gig1/1-1/8 always come up, rather than port1/1 mapping to Gig1/1, port1/2 mapping to Gig 1/2 , etc, so it’s not possible to link multiple devices together.

Hello,

what port mapping do you meen? What do you connect to the VSP?

Hi,

Here some explanations about the limitation.

The platform is “8284XSQ”.

@StephanH , it can’t be an XA as the XA has options for fragmentation and reduced MTU on logical interfaces that aren’t available here.

and we are limited to 9 usable ports: 1 OoB mgmt port and the 1/1 to 1/8.

The limitation of the number of ports is due to the virtualization of the OS with a vSwitch intentionally limited to 8 ports.

No way to go over.

I have 5 VSP’s in my lab which I am trying to link together, of which two of them have a vIST, connecting Device1-port1/1 to Device2-port1/1, on both devices ports Gig1/1-Gig1/8 come up.

Although GNS3 allows we to make connections from the other VSPs to the VSP-vist-pair, I cant see what Gig interfaces the additional connections are mapping to.

Better to open a new topic for this

use “show autotop nm” to check what switch is behind.
