MP presence is toggled when you enter the ipc toggle mp-presence command.
Active MP presence is displayed for the LP as shown in Table 35.
The threshold time is set in the chassis when you enter the command dm
mp-presence-threshold-time. This command displays a warning message in the LP console before
LP is reset after finding the Active MP.
The allowed threshold time is 0 to 35 seconds only. The maximum limit of 35 seconds is
maintained because the LP is reset on the MP absence in 35 seconds. The input value 0 clears
mp-presence-threshold-time.
Commands for setting mp-presence-threshold time are shown in Table 36.
The below warning message is displayed when the threshold time is reached.
mp_presence_threshold_log: LP will go for a reset in another xx seconds.
Rolling Reboot
The Rolling Reboot feature provides a solution for continuously rebooting the line card when a
system failure occurs from causes including BIST failure, ECC errors, module init failure, and
hardware failure during system initialization. When there is failure, the system automatically
reboots in an infinite loop until the failure is resolved. Repetitious reboot cycles consume CPU
resources, power, and result in unwanted IPC traffic to the MP.
When the system detects the continuous reboot of a line card, that line card is placed into
interactive or down state mode after ten (10) consecutive reboot cycles, and a failure message is
sent to the MP.
