MTUΒΆ
Default MTU interface is typically 1500. User can lower the value to cope with tunneling, or increase the value up to 9K to leverage jumbo support on the NIC.
To configure the MTU of the existing interface eth0
in vrf main
to
2000, do:
vrouter running config# vrf main
vrouter running vrf main# interface physical eth0
vrouter running physical eth0# mtu 2000
vrouter running physical eth0# commit
To display an interface mtu:
vrouter> show state / vrf main interface physical eth0
physical eth0

..
mtu 2000

The same configuration can be made using this NETCONF XML configuration:
vrouter> show config xml absolute vrf main interface physical eth0
<config xmlns="urn:6wind:vrouter">
<vrf>
<name>main</name>
<interface xmlns="urn:6wind:vrouter/interface">
<physical>
<name>eth0</name>
<mtu>2000</mtu>
(...)
</physical>
</interface>
</vrf>
</config>
