4.2.8 SNMP
4.2.8.1 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; you can use this menu to change the defaults or to add other
communities. Only the communities that you define using this menu will have access to the switch using
the SNMPv1 and SNMPv2c protocols. Only those communities with read-write level access will have
access to this menu via SNMP.
You should use this menu when you are using the SNMPv1 and SNMPv2c protocol: if you want to use
SNMP v3 you should use the User Accounts menu.
Configurable Data
SNMP Community Name - You can use this screen 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.
Client IP Address - Taken together, the Client IP 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 (IP Address or IP Mask) value is 0.0.0.0, access is allowed from any IP
address. Otherwise, every client's IP address is ANDed with the mask, as is the Client IP
Address, and, if the values are equal, access is allowed. For example, if the Client IP
Address and Client IP Mask parameters are 192.168.1.0/255.255.255.0, then any client
