SNMP Settings The Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches and other network devices. Use SNMP to configure system features for proper operation, monitor performance and detect potential problems in the Switch, switch group or network. Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB), which provides a standard presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network. 31

Switch>
In the above example, the command
show ip interface
is used to display information about the IP
interfaces created on this Switch. In this display we see that the IP address for this switch is
10.90.90.90
and the CIDR notation for the subnet mask is
/8
which translates to
255.0.0.0
. This information can
however be modified, as show below.
Switch> enable
Switch# configure terminal
Switch(config)# interface vlan 1
Switch(config-if)# ip address 192.168.1.1 255.255.255.0
Switch(config-if)#
In the above example,
1. We accessed the
Privileged EXEC Mode
by entering the command
enable
.
2.
Then we entered the
Global Configuration Mode
by entering the command
configure terminal
.
3.
Then we entered the
VLAN Configuration Mode
of the default VLAN, which isVLAN 1, by
entering the command
interface vlan 1
.
4.
Then we changed the IP address of the Switch to 192.168.1.1 and the subnet mask to
255.255.255.0 by entering the command
ip address 192.168.1.1 255.255.255.0
