Summary Non-configuration file getting loaded to startup-config through HTTP. A v6 ping with the v4 header destination address set to 224.0.0.2 (all routers addr) is not responded to. Certain packets match system rules that elevate the priority for protocol packets. User Impact Switch does not utilize invalid configuration file information. Earlier versions of startup-config are not available for fallback when overwritten with an invalid startup-config. Users are not able to ping over 6to4 tunnels using IPv6 addresses. Workaround In this case, an invalid configuration file was downloaded (on purpose) via the web. When the switch rebooted, it detected that the configuration file was invalid and overwrote the start-up config with the default configuration (an empty configuration). Users are advised to maintain off-line copies of switch configurations. Users can send pure IPv4 pings to the other end of the tunnel. Packets may be transmitted out of order when using priority flow control. Additionally, if the queue that the packets are put on is not enabled for lossless PFC, then the packets can be transmitted even when the port was told to pause. This may have an effect on connections that expect packet order to be maintained, e.g. FCoE. None. 22 System Firmware Version 4.1.0.6
