NX-OS Scheduler Job VRF for TFTP Backup via the Global Routing Table

350-601 By islever Editorial Last updated

Implement automation and scripting tools

Short answer

A Use the default VRF for the scheduler job so the TFTP copy uses the global routing table.

Question

Refer to the exhibit. An engineer is performing a Cisco Nexus 3000 Series Switch configuration backup with a TFTP server that is reachable in the global routing table. Which action completes the scheduler configuration? - Exhibit: NX-OS Scheduler Job VRF for TFTP Backup via the Global Routing Table
  1. Use the default VRF for the scheduler job. Correct Answer
  2. Configure the scheduler authentication password.
  3. Define the scheduler start time as required.
  4. Make the size of the job output lower than the size of the log file.

Key Takeaways

By default, file-copy operations in NX-OS (and scheduler jobs) use VRF management unless you explicitly set vrf default. If the TFTP server is in the global routing table (not the OOB management VRF), the scheduler job copy must use vrf default; otherwise the transfer fails because it looks in the management VRF.

NX-OS scheduler jobs execute CLI commands; when a copy command in the job targets a TFTP server reachable in the global routing table, you must specify vrf default (or omit VRF) so the copy uses the global table rather than the management VRF.

Common mistake: Assuming the start time (C) or authentication password (B) is missing. The exhibit already has 'time daily 55' defined and the job is authenticated by the logged-in user; the gap is the VRF — the copy needs vrf default to reach the global-table TFTP server.

Expert Analysis

Why the Answer Is Correct

The scheduler configuration is complete except for the VRF context of the TFTP copy. Because the TFTP server is reachable in the global routing table, the copy command inside the scheduler job must use vrf default (the default routing table), not VRF management. The start time ('time daily 55') and the job are already defined.

Why the Other Options Are Wrong

B. Scheduler authentication password is for AAA authentication of the scheduler user and is not the missing piece. C. Start time is already set ('time daily 55'). D. Job output size vs log file size is about log truncation, not connectivity to the TFTP server.

    A. I would select C. is wrong, since the "time daily 55"already defined that: For the time daily 55 command, the scheduler assumes a start time every day at 22:55 hours
  2. crooks_1988 👍 1
    B. is not because: switch(config) # scheduler aaa-authentication password [0 | 7] password Configures a password for the user who is currently logged in. - which is the case

    It is A for sure, else the command tftp is execute in vrf management
  4. udo2020 👍 1
    it is D because w/o this, the output will be truncated if its longer
  5. asd248402 👍 1 Answered A
    its a since the global routing is not the same as management vrf
