Cisco Nexus 1000V - Configuring the Basic Interface Parameters; Specifying an Interface to Configure

◦
If you configure an Ethernet port speed to a value other than auto (for example, 10, 100, or 1000
Mbps), you must configure the connecting port to match. Do not configure the connecting port to
negotiate the speed.
The device cannot automatically negotiate the Ethernet port speed and duplex modes if
the connecting port is configured to a value other than auto.
Note
Changing the Ethernet port speed and duplex mode configuration might shut down and
reenable the interface.
Note
•
To specify an interface in the CLI, use the following guidelines:
◦
For an Ethernet port, use the ethernet slot/port command, where slot is the module slot number
and port is the port number.
◦
For a vEthernet port, use the vethernet number command, where number is a number from 1 to
1048575.
◦
A space is not required between the interface type and the slot/port or interface number. For
example, for the Ethernet slot 4, port 5 interface, you can specify either the ethernet 4/5 command
or the ethernet4/5 command.
•
Jumbo frames are only supported on the vmxnet3 driver. Attempts to change the MTU appear to succeed
but the adapter always drops frames larger than 1500 bytes. For more information, see the VMware KB
article http://kb.vmware.com/selfservice/microsites/search.do?language=en_
