Usage¶

In this section, it is assumed that Virtual Accelerator has been properly installed and configured. See Getting Started for more details.

Fast path¶

You can manage MACVLAN devices via the fp-cli commands below.

Displaying MACVLAN devices¶

Synopsis

macvlan

Example

<fp-0> macvlan
ntfp2-vr0:
        macvlan3-vr0: mode: private
        macvlan1-vr0: mode: private
ntfp3-vr0:
        macvlan2-vr0: mode: passthru

Displaying MACVLAN information¶

Synopsis

iface

Example

<fp-0> iface
...
10:macvlan1 [VR-0] ifid=10 (virtual) <FWD4|FWD6> (0x18)
        type=macvlan mac=26:ff:f5:17:53:6d mtu=1500 tcp4mss=0 tcp6mss=0
        IPv4 routes=0  IPv6 routes=0
        if_ops: rx_dev=none rx_early=none tx_dev=macvlan ip_output=none
        mode private, link ntfp2
11:macvlan2 [VR-0] ifid=11 (virtual) <FWD4|FWD6> (0x18)
        type=macvlan mac=de:ed:03:d6:ff:33 mtu=1500 tcp4mss=0 tcp6mss=0
        IPv4 routes=0  IPv6 routes=0
        if_ops: rx_dev=none rx_early=none tx_dev=macvlan ip_output=none
        mode passthru, link ntfp3
12:macvlan3 [VR-0] ifid=12 (virtual) <FWD4|FWD6> (0x18)
        type=macvlan mac=a6:09:fe:65:09:c7 mtu=1500 tcp4mss=0 tcp6mss=0
        IPv4 routes=0  IPv6 routes=0
        if_ops: rx_dev=none rx_early=none tx_dev=macvlan ip_output=none
        mode private, link ntfp2
...

Providing options¶

Some capabilities can be tuned for this module.

--ifaces¶

Maximum number of MACVLAN interfaces

Default value: 127
Memory footprint per MACVLAN interfaces: 50 B
Range: 0 .. 5000

Example

FP_OPTIONS="--mod-opt=macvlan:--ifaces=256"

Then fast path can manage up to 256 MACVLAN interfaces.

--hash-order¶

Size order of MACVLAN interfaces hash table. Value automatically updated if --ifaces is changed.

Default value: 8
Range: 1 .. 31

Example

FP_OPTIONS="--mod-opt=macvlan:--hash-order=9"

Tip

To get optimal performance, apply the following ratios to the two parameters:

Parameter	Value
–hash-order	`N`
–ifaces	`2 ** N`

Note

See Fast Path Capabilities documentation for impact of the available memory on the default value of configurable capabilities
