SYNOPSIS
vustack [ options ...] stack command [ args ]
DESCRIPTION
vunet is the VUOS module for networking virtualization. Networking stacks can be loaded using vumount (1) and are identified by a pathname: the mount point. vustack selects the stack to use among those available; command runs using the stack selected vustack .
OPTIONS
-h , --help

-s , --supported
select the stack only for the protocol families supported by stack .
-f list , --family list , --families list
select the stack for the protocol families in list . list is a comma separated list of protocol names or numbers.
-v , --verbose
print the list of protocol families object of the stack selection.
EXAMPLES
Load vunet and mount a stack:
$ vu_insmod
vunet
$ vumount -t vunetvdestack vde:// /dev/net/vde
Run ip link using the stack mounted in /dev/net/vde:
$ vustack
/dev/net/vde ip link
1: lo: *LOOPBACK* mtu 65536 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: vde0: *BROADCAST,MULTICAST* mtu 1500 qdisc noop state
DOWN mode DEFAULT group default qlen 1000
link/ether 5a:1e:97:fa:ab:a3 brd ff:ff:ff:ff:ff:ff
Run ip link set vde0 up selecting /dev/net/vde only for the families supported by vunetvdestack:
$ vustack -s -v
/dev/net/vde ip link set vde0 up
Using /dev/net/vde for the following address families:
inet(2) inet6(10) netlink(16) packet(17)
mount a null stack and use it to disable netlink:
$ vumount -t
vunetnull vde:// /dev/net/null
$ exec vustack -f netlink -v /dev/net/null bash
Using /dev/net/null for the following address families:
netlink(16)
$ ip addr
Cannot open netlink socket: Address family not supported by
