hold for a specific VRF. This command does not apply to the management VRFs.

● show ipv6 route — display the IPv6 routes.
ip mtu
Set the IP MTU (frame size) of the packet the RPM transmits for the line card interface. If the packet must be fragmented, Dell
Networking OS sets the size of the fragmented packets to the size specified in this command.
Syntax
ip mtu value
To return to the default IP MTU value, use the no ip mtu command.
Parameters
value Enter the maximum MTU size if the IP packet is fragmented. The range is from 576
to 9234. The default is 1500 bytes.
Defaults 1500 bytes

Usage
Information
When you enter the no mtu command, Dell Networking OS reduces the ip mtu value to 1536 bytes. To
return the IP MTU value to the default, use the no ip mtu command.
Starting with Dell Networking OS Release 9.2(0.2), the ip mtu command is not supported to configure
the IP MTU value that is used when the IP packet is fragmented. Instead of having to configure the IP
MTU value, this value is automatically computed by the software when you configure an interface. As a
result, the ip mtu command is not available for configuration. However, you can continue to specify the
link MTU value by using the mtu command.
