Frequently Queried Log Messages Chapter 4 Using the CSS Logging Features Table 4-8 Cisco 11500 Series CSS Log Messages (continued) Log Message (sys.log: Subsystem Name, Level, and Message) Cause and Resolution IPV4-4 Ipv4SfmForwTx: unknown logical port in buffer A link became unavailable while an ARP or other IPV4 packets were in transit. When this occurred, the CSS chose a logical port to transmit from, formatted the packets, and then attempted to transmit the packets. At the point when the CSS attempted to transmit packets, the logical port was no longer available. This is an informational message. No further action is required. IPV4-4: Ipv4ApIoctl: unknown command: 1074031872 This is an informational message. No further action is required. IPV4-4: Ipv4SfmForwRx: buffer length (872) less than IP length (1004) IP packets have been corrupted and the IP header Total Length value does not match with the actual length of the packet. In this case, the SFP receives less total bytes than expected from the IP header length. This message may be related to hardware problems or errors on the line (corrupted packets). Use the show mibii or show ether-errors command to look for errors on one of the CSS ports. 4-46 Cisco Content Services Switch Administration Guide OL-5647-02
