To meet the requirements of performing a backup and restore of the Cisco Nexus 5000 Series Switch configuration using UDP as the only protocol, the network engineer must follow these steps:
* Perform a startup-config backup to a TFTP server. The startup-config file contains the configuration that is applied when the switch boots up. To backup this file to a TFTP server, the engineer can use the copy startup-config tftp: command, and specify the IP address or hostname of the TFTP server and the destination filename. For example:
switch# copy startup-config tftp: Enter hostname for the tftp server: 10.10.10.10 Enter destination filename:
backup-config
* Copy backup-config from the backup server to the running-config file. The running-config file contains the configuration that is currently active on the switch. To restore this file from the backup-config file on the TFTP server, the engineer can use the copy tftp: running-config command, and specify the IP address or hostname of the TFTP server and the source filename. For example:
switch# copy tftp: running-config Enter hostname for the tftp server: 10.10.10.10 Enter source filename:
backup-config
These steps will allow the engineer to backup and restore the switch configuration using UDP as the only protocol, as TFTP is a UDP-based protocol. The backup-config file can be used when the current working configuration of the switch gets corrupted, as required by the goal. References :=
