information and forward the data to a network management station, where network managers perform diagnostic and advanced planning operations. The use of SNMP, a common and
The Management Information Base (MIB) is a database that stores all of the collected statistics and holds them in specific structures. MIB data includes configuration and control parameters and statistical data such as the number of errors sent and received on a port.
Additional information is collected by the following MIBS and RMONs:
•MIB II
•Bridge MIB
•Groups 1, 2, 3, and 9 RMON
—Group 1: Stats (EtherStats Table)
—Group 2: History (history control Table, Ether history control Table)
Only etherStats is supported by history, and the number of buckets is limited to 150.
—Group 3: Alarm (alarm Table)
—Group 9: Events (event Table, log Table)
Note: EtherStats Alarms and Events entries are saved through power cycle of the switch. History entries are not saved through a power cycle. Alarms, events, and logs are limited to 20 entries each.
The BayStack switch has a management core that gathers statistics from each of the network ports; maintains the MIB; and, when a message for the SNMP manager arrives, retrieves the information, puts it into the right form, and sends it out the appropriate port.
Access to the switch through SNMP is controlled by community names.
The community names set for the switch must match those used by the SNMP management station for successful communication to occur. The switch uses two community names. The “public” community name allows
