Examples # Create event 10 in the RMON event table. system-view [Sysname] rmon event 10 log owner user1 rmon history Syntax rmon history entry-number buckets number interval sampling-interval [ owner text ] View undo rmon history entry-number Layer 2 Ethernet interface view Default level 2: System level Parameters entry-number: Specifies the history control entry index, which ranges 1 to 65535. buckets number: Specifies the history table size for the entry, which ranges from 1 to 65535. interval sampling-interval: Specifies the sampling period, which ranges from 5 to 3600 seconds. owner text: Specifies the owner of the entry, a case-sensitive string of 1 to 127 characters that can contain spaces. Description Use rmon history to create an entry in the RMON history control table. Use undo rmon history to remove a specified entry from the RMON history control table. After an entry is created, the system periodically samples the number of packets received/sent on the interface, and saves the statistics as an instance under the leaf node of the etherHistoryEntry table. The maximum number of statistics records can be saved for the entry is specified by buckets number. If the maximum number of the statistics records for the entry has been reached, the system deletes the earliest record for the latest one. The statistics include total number of received packets on the interface, total number of broadcast packets, total number of multicast packets in a sampling period, and so on. You can successfully create a history control entry, even if the specified bucket size exceeds the history table size supported by the device. However, the effective bucket size will be the actual value supported by the device. To view the configuration result, use the display rmon history command. You can configure multiple history control entries for one interface, but must make sure their entry numbers and sampling intervals are different. The device supports up to 100 history control entries. Related commands: display rmon history.
