ExtremeWare 7.7 Command Reference Guide 713
configure sys-hardware-recovery
configure sys-hardware-recovery [log | card-reset | card-offline |
fabric-reset | system-offline | system-reset]
Description
Configures a recovery mechanism for a switch or module with a processor in a hang state.
NOTE
This command is available only on the “i” series switches.
Syntax Description
Default
The default is log.
Usage Guidelines
During multicast packet processing or broadcast storms, certain processor chips in the switch that are
involved with QoS and packet scheduling can enter a hang state and cannot independently recover.
This command enables dynamic monitoring of these processors and configures a hardware recovery
mechanism for a system with such a hung processor.
NOTE
The system hardware recovery mechanism attempts to recover from a hung state that is due to
multicast or broadcast storms. This recovery mechanism does not provide recovery from a physical
hardware failure.
log Posts a CRIT message to the syslog.
card-reset Shuts down an I/O module and brings it up again. After three resets, the I/O module is taken off
line.
Shuts down an MSM.
NOTE: This option is available only on BlackDiamond switches.
card-offline Checks for the hang condition three times, then shuts down all the ports on an I/O module and
places the module in an offline state. The system is still up and running and can access data
registers on the module.
Checks for the hang condition three times, then shuts down an MSM.
NOTE: This option is available only on BlackDiamond switches.
fabric-reset
system-offline Summit “i” series switches: Shuts down all ports in the system but leaves the system up and
running.
BlackDiamond and Alpine switches: Shuts down all ports and places them in an offline state.
Leaves the system up and running.
