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.
• Rolling Reboot Detection relies on the bootprom and Linux kernel working properly.
• Rolling Reboot Detection feature would only work during system boot-up time period and would
not work for an unexpected reboot after a period of time of 30 minutes after boot up. If your
system reboots after being up and working properly in 30 or more minute intervals, the RRD
feature will not be activated.
Collecting a limited supportSave on the Rolling Reboot Detection
1. Log into the switch on the admin account.
A user account with admin privileges will not be able to collect a limited supportSave.
2. After you see the message in the example below, press Enter.
3. Enter the supportSave command to go into interactive mode.

5. Once the supportSave is completed, contact you service support provider to provide them with

FC-FC routing connectivity
This section describes tools you can use to troubleshoot Fibre Channel routing connectivity and
performance.
Generate and route an ECHO
The FC-FC Routing Service enables you to route the ECHO generated when an fcPing command is
issued on a switch, providing fcPing capability between two devices in different fabrics across the
FC router.
