ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual To display this page, click System  SNMP  SNMP V1/V2  Community Configuration. A screen similar to the following displays. 1. Use Community Name to reconfigure an existing community, or to create a new one. Use this pull-down menu to select one of the existing community names, or select 'Create' to add a new one. A valid entry is a case-sensitive string of up to 16 characters. 2. Client Address - Taken together, the Client Address and Client IP Mask denote a range of IP addresses from which SNMP clients may use that community to access this device. If either (Client Address or IP Mask) value is 0.0.0.0, access is allowed from any IP address. Otherwise, every client's address is ANDed with the mask, as is the Client Address, and, if the values are equal, access is allowed. For example, if the Client Address and Client IP Mask parameters are 192.168.1.0/255.255.255.0, then any client whose address is 192.168.1.0 through 192.168.1.255 (inclusive) will be allowed access. To allow access from only one station, use a Client IP Mask value of 255.255.255.255, and use that machine's IP address for Client Address. 3. Client IP Mask - Taken together, the Client Address and Client IP Mask denote a range of IP addresses from which SNMP clients may use that community to access this device. If either (Client Address or IP Mask) value is 0.0.0.0, access is allowed from any IP address. Otherwise, every client's address is ANDed with the mask, as is the Client Address, and, if the values are equal, access is allowed. For example, if the Client Address and Client IP Mask parameters are 192.168.1.0/255.255.255.0, then any client whose IP address is 192.168.1.0 through 192.168.1.255 (inclusive) will be allowed access. To allow access from only one station, use a Client IP Mask value of 255.255.255.255, and use that machine's IP address for Client Address. 4. Use Access Mode to specify the access level for this community by selecting Read/Write or Read Only from the pull-down menu. 5. Use Status to specify the status of this community by selecting Enable or Disable from the pull-down menu. If you select enable, the Community Name must be unique among all valid Community Names or the set request will be rejected. If you select disable, the Community Name will become invalid. 6. Click ADD to add the currently selected community to the switch. 7. Click DELETE to delete the currently selected Community Name. Chapter 2. Configuring System Information | 95
