SNMP
Simple Network Management Protocol (SNMP) works by sending messages called protocol data
units (PDUs) to different parts of a network. SNMP compliant devices, called agents, store data
about themselves in Management Information Bases (MIBs) and return this data to the SNMP
requesters. The console server uses the net-snmp package. See http://www.net-snmp.org for more
information.
NOTE: Check the SNMP configuration before gathering information about the console server by SNMP. There
are different types of attacks an unauthorized user may implement to retrieve sensitive information contained in
the MIB. By default, the SNMP configuration in the console server does not permit the public community to read
SNMP information.
In order to configure SNMP v1/v2, enter the following command. Refer to Table 2.7 for a list
of parameters.
cli> config network snmp v1/v2 [parameter] <value>
leftsubnet
rightsubnet
<n.n.n.n/n> The netmask of the subnetwork where the host resides.
NOTE: Use CIDR notation. The IP number followed by a
slash and the number of ‘one’ bits in the binary notation of
the netmask. For example, 192.168.0.0/24 indicates an IP
address where the first 24 bits are used as the network
address. This is the same as 255.255.255.0.
secret <string> Pre-shared password between left and right users.
