Can't use ZTP to install sw and provision the router.

The following logs are required to triage the ZTP issue:

1. Interface name and its speed. (RSI is required)
2. DHCP server config file, which is used for the ZTP.
3. We need the following logs collected from the router, right after the issue is noticed.

a. RSI

b. Entire /var/log

c. Debug-collector output

d. picd traces

e. journalctl logs.

Please reach out to JTAC/CFTS if you have issues in collecting the recommended logs.
