Draw the SNMP Access Policy (as in Figure ) for the following scenario. Suppose a corporation with headquarters in Riyadh and domains or network sites in Riyadh, Jeddah, and Dammam. Let Manager 1 and community 1 be associated with Jeddah, Manager 2 and community 2 be associated with Riyadh, and Manager 3 and community 3 be associated with Dammam. Let Manager 4 be the overall network management system, the Manager of Managers (MOM). Each Manager manages 2 Agents associated with network elements in its domain only. So that, Manger 1 does not have the view of Riyadh or Dammam, Manger 2 cannot perform operations on network elements belonging to Jeddah or Dammam domains, and Manger 3 cannot communicate with Agents in Jeddah or Riyadh. However, Manger 4 has all community names defined in its profile and hence has the view of the total enterprise network in Riyadh, Jeddah, and Dammam.
