Dell PowerVault DR2000v - Manual (Page 42)

Many Gigabit Ethernet switches and Gigabit Ethernet network interface cards support jumbo frames. Some Fast
Ethernet switches and Fast Ethernet network interface cards (NICs) also support jumbo frames.
Some computer manufacturers use 9000 bytes as the conventional limit for jumbo frame sizes. Internet Protocol (IP)
subnetworks require that all hosts in a subnet have an identical MTU.
Consequently, interfaces that use a standard frame size and those that use a jumbo frame size should not be in the same
subnet. To reduce the chance of interoperability issues, NICs capable of jumbo frames require special configurations to
use jumbo frames. For more information, contact your Dell Support representative for assistance.
To verify that the destination system can support a specific frame size you want to attempt, use the following DR Series
system CLI commands and specify the frame size in bytes using the following command as an example:
network --ping --destination --size
network --update
Description
The command updates bonding and individual interface information.
Syntax
network --update [--bondif ]
[--nwif ]
[--mode < ALB | 802.3ad>]
[--name < DNS name >]
[--mtu ]
--bondif Bond interface to update.
--nwif Eth interface to update.
--mode Bonding mode to use.
--name DNS name for the interface.
--mtu Ethernet MTU to use (valid range is 512 - 9000).
For example, to update bond1 to use a different MTU parameter, run the command: network --update --
bondif bond1 --mtu 5000
Result
WARNING: Incorrectly setting the MTU size will cause the DR appliance to not
respond.
Please verify that the switch is enabled and capable of supporting an MTU size
that is equal to or larger than the value being set.
Do you want to continue (yes/no) [n]? y
Interface update successful.
network --factory_reset
Description
The command resets bond0 Slave Interfaces according to the option of auto_bonding_speed.
Syntax
network --factory_reset [--auto_bonding_speed <1G|10G>]
--auto_bonding_speed The speed of the device (1G or 10G)
to bond on restart.
