3. BOOTP configuration
Command Explanation
VLAN Port Mode
ip bootp-client enable
no ip bootp-client enable
Enable the switch to be a BootP client and obtain IP
address and gateway address through BootP
negotiation; the “no ip bootp-client enable”
command disables the BootP client function.
4. DHCP configuration
Command Explanation
VLAN Port Mode
ip bootp-client enable
no ip bootp-client enable
Enable the switch to be a DHCP client and obtain IP
address and gateway address through DHCP
negotiation; the “no ip bootp-client enable”
command disables the DHCP client function.
4.4 SNMP Configuration
4.4.1 Introduction to SNMP
SNMP (Simple Network Management Protocol) is a standard network management protocol widely used in
computer network management. SNMP is an evolving protocol. SNMP v1 [RFC1157] is the first version of
SNMP which is adapted by vast numbers of manufacturers for its simplicity and easy implementation; SNMP
v2c is an enhanced version of SNMP v1, which supports layered network management; SNMP v3
strengthens the security by adding USM (User-based Security Mode) and VACM (View-based Access
Control Model).
SNMP protocol provides a simple way of exchange network management information between two points in
the network. SNMP employs a polling mechanism of message query, and transmits messages through UDP
(a connectionless transport layer protocol). Therefore it is well supported by the existing computer networks.
SNMP protocol employs a station-agent mode. There are two parts in this structure: NMS (Network
Management Station) and Agent. NMS is the workstation on which SNMP client program is running. It is the
core on the SNMP network management. Agent is the server software runs on the devices which need to be
managed. NMS manages all the managed objects through Agents. The switch supports Agent function.
The communication between NMS and Agent functions in Client/Server mode by exchanging standard
messages. NMS sends request and the Agent responds. There are seven types of SNMP message:

Get-Request

Get-Response

Get-Next-Request
