Enabling Tracing
Tracing is disabled by default. To set a trace level for the purpose of debugging or troubleshooting,
perform the following steps:
1. Enter global-configuration mode.
HB-IB> enable
HB-IB configure
HB-IB(config)
2. View the trace help output, as the number of applications and modules may have changed.
HP-IB(config)# trace app ?
app <1-25>
app numbers:
APP_ID_CLI = 1
APP_ID_OSPF = 2
APP_ID_RIP = 3
APP_ID_IP_AGENT = 22
APP_ID_FIB_AGENT = 23
APP_ID_KERNEL = 24
APP_ID_CARD_AGENT = 25
APP_ID_SM = 26
3. Set the application value, the module value, the trace level, the flowmask, and the card
number on which you want to run a trace.
Refer to “About Logging and Tracing” (page 125).
HP-IB(config)# trace app 4 module 36 level very-verbose
