62 CHAPTER 7: STATUS MONITORING AND STATISTICS Table 8 RMON support supplied by the Switch RMON group Alarms Events Support supplied by the Switch A new or initialized Switch has the following alarm(s) defined for each port: For more information about the alarms setup on the Switch, see "Alarm Events" on page 62. A new or initialized Switch has Events defined for use with the default alarm system. When using the RMON features of the Switch, note the following: ■ After the default sessions are created, they have no special status. You can delete or change them as required. ■ The greater the number of RMON sessions, the greater the burden on the management resources of the Switch. If you have many RMON sessions, the forwarding performance of the Switch is not affected but you may experience slow response times from the Web interface. Alarm Events You can define alarms for the Switch. The events that you can define for each alarm and their resulting actions are listed in Table 9.
