NOTE: When setting or changing the MTU value, make sure to verify that the Ethernet network switch is capable of supporting an MTU size that is equal to or larger than the value being set. Any mismatch in MTU values between the clients, the Ethernet network switch, and the DR Series system will make it inoperable. The relationship of jumbo frames to MTU is discussed in this topic. NOTE: When using the DR Series system CLI --setbonding and --mtu commands, a warning dialog displays with the following message: Incorrectly setting the MTU size will cause the DR4000 to not respond. You will need to log in to the system console and use the network --setbonding --bondif bond0 --mtu 1500 command to resolve the issue. 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) ? CAUTION: If the existing bonding setting is changed, the connection to the DR Series system may be lost unless you are sure that the DR Series system can accept this bonding type. In computer networking, jumbo frames are Ethernet frames with more than 1500 bytes of payload (but in some cases, jumbo frames can carry up to 9000 bytes of payload). 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 --nwif --mode --name --mtu Bond interface to update. Eth interface to update. Bonding mode to use. DNS name for the interface. 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 42

When setting or changing the MTU value, make sure to verify that the Ethernet network switch is capable

When using the DR Series system CLI

commands, a warning dialog displays with
the following message:
Incorrectly setting the MTU size will cause the DR4000 to not respond. You will
need to log in to the system console and use the
network --setbonding --bondif
bond0 --mtu 1500
command
to resolve the issue. 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

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 <ip address> --size <number of bytes>
network --update
Description
The command updates bonding and individual interface information.
Syntax
network --update [--bondif <bondN>]
[--nwif <ethN>]
[--mode < ALB | 802.3ad>]
[--name < DNS name >]
[--mtu
<Supported MTU range 512 - 9000>]
--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
