IPv6 Diagnostic and Troubleshooting Debug/Syslog for IPv6 Debug/Syslog for IPv6 The Debug/System logging (Syslog) for IPv6 feature provides the same logging functions as the IPv4 version, allowing you to record IPv4 and IPv6 Event Log and debug messages on a remote device to troubleshoot switch or network operation. For example, you can send messages about routing misconfigura tions and other network protocol details to an external device, and later use them to debug network-level problems. Configuring Debug and Event Log Messaging To specify the types of debug and Event Log messages that you want to send to an external device: ■ Use the debug < debug-type > command to send messaging reports for the following types of switch events: • DHCP snooping events • Dynamic ARP protection events • Events recorded in the switch's Event Log • IPv4 OSPF and RIP routing events • IPv6 DHCPv6 client and Neighbor Discovery events • LLDP events ■ Use the logging < severity severity-level | system-module system-module> command to select a subset of Event Log messages to send to an external device for debugging purposes according to: • Severity level • System module 7-11
