11.2.8 Managing SNMP and Trap
11.2.8.1 Configuring SNMP Community Configuration Page
By default, two SNMP Communities exist:
ï€ private, with 'Read/Write' privileges and status set to enable
ï€ 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 Criteria
Community - 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.
Access Mode - Specify the access level for this community by selecting Read/Write or Read Only
from the pull down menu.
Status - 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.
Configurable Data
Community - The snmp Community Name, it identifies each SNMP community. Community names
in the SNMP community must be unique. 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 whose IP address is 192.168.1.0 through 192.168.1.255
