Description

After receiving a burst of fragmented ICMP packets, the chassis loses connection to the FEB and FPC. The chassisd connection to FRU is terminated, and FEB and FPC reboot, causing a permanent interruption of forwarding. Administrative connection to the FEB or FPCs is impossible via 'vty' or 'cty'. The router must be rebooted to restore administrative connectivity to the FEB or FPCs and resume normal operation.
