NOTE: When you load the startup configuration or a configuration file from a network server such as TFTP to the
running configuration, the configuration is added to the running configuration. This does not replace the existing running
configuration. Commands in the configuration file has precedence over commands in the running configuration.
Configure the Overload Bit for a Startup Scenario
For information about setting the router overload bit for a specific period of time after a switch reload is implemented, see the
Intermediate System to Intermediate System (IS-IS) section in the Dell Command Line Reference Guide for your system.
Using HTTP for File Transfers
Stating with Release 9.3(0.1), you can use HTTP to copy files or configuration details to a remote server. To transfer files to an
external server, use the copy source-file-url http://host[:port]/file-path command.
Enter the following source-file-url keywords and information:
● To copy a file from the internal FLASH, enter flash:// followed by the filename.
● To copy the running configuration, enter the keyword running-config.
● To copy the startup configuration, enter the keyword startup-config.
● To copy a file on the USB device, enter usbflash:// followed by the filename.
In the Dell EMC Networking OS release 9.8(0.0), HTTP services support the VRF-aware functionality. If you want the HTTP
server to use a VRF table that is attached to an interface, configure that HTTP server to use a specific routing table. You can
use the ip http vrf command to inform the HTTP server to use a specific routing table. After you configure this setting, the
VRF table is used to look up the destination address.
NOTE: To enable HTTP to be VRF-aware, as a prerequisite you must first define the VRF.
You can specify either the management VRF or a nondefault VRF to configure the VRF awareness setting.
When you specify the management VRF, the copy operation that is used to transfer files to and from an HTTP server utilizes
the VRF table corresponding to the Management VRF to look up the destination. When you specify a nondefault VRF, the VRF
table corresponding to that nondefault VRF is used to look up the HTTP server.
However, these changes are backward-compatible and do not affect existing behavior; meaning, you can still use the ip http
source- interface command to communicate with a particular interface even if no VRF is configured on that interface
NOTE: If the HTTP service is not VRF-aware, then it uses the global routing table to perform the look-up.
To enable an HTTP client to look up the VRF table corresponding to either management VRF or any nondefault VRF, use the ip
http vrf command in CONFIGURATION mode.
● Configure an HTTP client with a VRF that is used to connect to the HTTP server.
CONFIGURATION MODE
DellEMC(conf)#ip http vrf {management | <vrf-name>}
View Configuration Files
Configuration files have three commented lines at the beginning of the file, as shown in the following example, to help you
track the last time any user made a change to the file, which user made the changes, and when the file was last saved to the
startup-configuration.
In the running-configuration file, if there is a difference between the timestamp on the “Last configuration change” and
“Startup-config last updated,” you have made changes that have not been saved and are preserved after a system reboot.
Example of the show running-config Command
DellEMC#show running-config
