Description

-mtuSize

Type the maximum transmission unit packet size (in bytes) for the port:

If an Ethernet port carries File interfaces only, the MTU size can be set to a custom value between 1280 and 9216.
If an Ethernet port carries iSCSI interfaces, the allowed MTU sizes are 1500 and 9000.

Specific I/O modules may also restrict allowed range for MTU size value. The MTU size values of 1500 bytes (default) and 9000 bytes (jumbo frame) are supported by all interfaces and I/O modules.

-speed

Type the port speed. Available speed attribute contains the list of valid values.

NOTE: The port will be link down temporarily during change of speed.

Example

The following command sets the MTU size for Ethernet port 0 (eth0) on SP A to 9000 bytes:

uemcli /net/port/eth –id spa_eth0 set –mtuSize 9000

Storage system address: 10.0.0.1
Storage system port: 443
