944 CHAPTER 76: RMON CONFIGURATION
n
■ Two entries with the same configuration cannot be created. If the parameters
of a newly created entry are identical to the corresponding parameters of an
existing entry, the system considers their configurations the same and the
creation fails. Refer to Table 75 for the parameters to be compared for different
entries.
■ The system limits the total number of all types of entries. When the total
number of an entry reaches the maximum number of entries that can be
created, the creation fails.
■ When you create an entry in the history table, if the specified buckets number
argument exceeds the history table size supported by the device, the entry will
be created. However, the validated value of the buckets number argument
corresponding with the entry is the history table size supported by the device.
