3Com 5500 SI - Switch - Stackable, Configuration Manual

OSPF Configuration 253
Perform the following configuration in System View.
By default, OSPF TRAP function is disabled, so the switch does not send TRAP packets
when any OSPF process is abnormal. The configuration is valid to all OSPF processes if
you do not specify a process ID.
For detailed configuration of SNMP TRAP, refer to “System Management" on .
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.
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 the above configuration, execute
display
command in any view 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.
