Required
Use at least one
command.
NOTE:
•
A new entry cannot be created if its parameters are identical with the corresponding parameters of an
existing entry. If the created entry is a history entry, it will be compared with the existing history entries
only on the same interface. See
for the parameters to be compared for different entries.
•
The system limits the total number of each type of entries (see
for the detailed numbers). When
the total number of an entry reaches the maximum number of entries that can be created, the creation
fails.
