Description
The command does not start the specific ethernet device(s) on restart.
Syntax
network --disable [--bondif <bond0,bond1,...,bondN>]
[--nwif <eth0,eth1,...,ethN>]
--bondif Bond interface(s) to delete.
--nwif Eth interface(s) to dele
|
|
NOTE: You cannot disable eth interfaces which are part of a bond. |
For example, to disable eth2, run the command: network --disable --nwif eth2
Result
Interface device operation successful. Please restart networking for the changes to take effect.
Isolates a variety of networking issues that you might encounter while running a DR Series system. When you can isolate a problem or issue to a specific cause, you can better understand and resolve it. The DR Series system CLI network --troubleshoot command and its options allow you to perform basic troubleshooting checks on the state of a DR Series system.
Description
|
|
NOTE: When entering the network --troubleshoot command string, the DR Series system checks and displays the current state for all of the --troubleshoot options. To limit the type of network troubleshooting check you want to display, define the command string to a specified check (or checks). For example, using network --troubleshoot --gateway, displays the status of the gateway for a DR Series system (for details, see network --troubleshoot [--gateway]). |
