After RRD is activated, admin level permission is required to log in. Enter the supportShow or
supportSave command to collect a limited amount of data to resolve the issue.
ATTENTION
The limited supportSave used with the RRD feature does not support USB.
Restrictions
The following restrictions are applicable on the RRD feature:
•
The RRD works only on CFOS-based systems and is not available on AP blades.
•
If FIPS mode is enabled, then the RRD feature works in record-only mode.
•
RRD relies on the bootprom and Linux kernel working properly.
•
RRD only works during the 30 minutes immediately after the switch boots. If the switch does
not reboot for 30 minutes, then RRD is deactivated.
Collecting a limited supportSave on the Rolling Reboot Detection
1. Log in to the switch on the admin account.
A user account with admin privileges is not able to collect a limited supportSave.
2. After you see the message in the following example, press Enter.
3. Enter the supportSave command to go into interactive mode.
4. Respond to the prompts.
5. Once the supportSave is completed, contact you service support provider to provide them with
the data.
