3Com Switch 7700 Configuration Manual page 131

Enabling/Disabling OSPF TRAP Function
Table 51
Operation
Disable OSPF TRAP function
By default, the OSPF TRAP function is disabled so the switch does not send TRAP
packets when any OSPF process is abnormal. The configuration is valid for all OSPF
processes if you do not specify a process ID.
For detailed configuration of SNMP TRAP, "System Management" on page 323.
Resetting the OSPF Process
If the undo ospf command is executed on a router and then the ospf command
is used to restart the OSPF process, the previous OSPF configuration is lost. With
the reset ospf command, you can restart the OSPF process without losing the
previous OSPF configuration.
Perform the following configuration in user view.
Table 52 Resetting the OSPF Process
Operation
Reset the OSPF process
Resetting the OSPF process can immediately clear the invalid LSAs, make the
modified router ID effective or re-elect the DR and BDR.
Displaying and Debugging OSPF
After configuring OSPF, execute the display command in all views to display the
operation of the OSPF configuration, and to verify the effect of the configuration.
Execute the debugging command in user view to debug the OSPF module.
