74 Serviceability Tracing Packet Commands Debug commands cause the output of the enabled trace to display on a serial port or telnet console. Note that the output resulting from enabling a debug trace always displays on the serial port. The output resulting from enabling a debug trace displays on all login sessions for which any debug trace has been enabled. The configuration of a debug command remains in effect the whole login session. The output of a debug command is always submitted to the syslog utility at a DEBUG severity level. As such, it can be forwarded to a syslog server, stored in the buffer log, or otherwise processed in accordance with the configuration of the syslog utility. Configuration of console logging in the syslog utility is not required in order to view the output of debug traces. Debug commands are provided in the normal CLI tree. Debug settings are not persistent and are not visible in the running configuration. To view the current debug settings, use the show debug command. The output of debug commands can be large and may adversely affect system performance. Enabling debug for all IP packets can cause a serious impact on the system performance; therefore, it is limited by ACLs. This means debug can be enabled for IP packets that conform to the configured ACL. This also limits the feature availability to only when the QoS component is available. Debug for VRRP and ARP are available on routing builds. Commands in this Chapter This chapter explains the following commands: debug arp debug auto-voip debug clear debug ip igmp debug ip mcache debug ip pimdm packet debug ipv6 pimdm debug rip debug ipv6 pimsm debug sflow debug isdp debug spanning-tree Serviceability Tracing Packet Commands 1583
