Web Management User Guide Community Configuration By default, two SNMP Communities exist: • Private, with Read/Write privileges and status set to Enable. • Public, with Read Only privileges and status set to Enable. These are well-known communities. Use this page to change the defaults or to add other communities. Only the communities that you define using this page will have access to the switch using the SNMPv1 and SNMPv2c protocols. Only those communities with read/write level access can be used to change the configuration using SNMP. Use this page when you are using the SNMPv1 and SNMPv2c protocol. If you want to use SNMP v3 you should use the User Accounts menu. 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. 65

Use this pull-down menu to select one of the existing community names, or select

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.
