Note: Transparent VLAN tagging does not occur on any VLAN packets that are sent
with VLAN configuration mode in the guest operating system on the VF.
Transmission Rate Configuration
Configure the transmission rate limit (TX-RATE) on a VF interface from the hypervisor
using the following IP command syntax:
# ip link set eth vf rate
where:

eth is the interface corresponding to the physical function.

is the VF number corresponding to the interface that you are
configuring the TX-rate.

is the transmission rate limit, in Mb/s.
For example, to set a TX-RATE of 5000 Mb/s for the VF 0, run
# ip link set eth0 vf 0 rate 5000
Link State Configuration
This section provides link state configuration for a VF in the newer CNAs (for example,
the OCe14000-series adapters).
Configure the link state on a VF interface from the hypervisor using the following IP
command syntax:
#ip link set eth vf state < auto | enable | disable >
where:

eth is the interface corresponding to the physical function

is the VF number corresponding to the interface for which the link state
is being configured

auto - VF link state will reflect the PF link state

enable - VF link state will be always up

disable - VF link state will be always down
Viewing VF Properties
To view the properties configured to VFs attached to a PF, use the following IP
command syntax:
# ip link show eth
where eth is the interface corresponding to the physical function.
For example, to view the properties of a PF at “eth0” (which has VFs 0, 1 associated
with it), run the following command in the hypervisor:
# ip link show eth0
Expected example output:
eth0: mtu 1500 qdisc mq state UP qlen 1000
