Dan Medhurst Question 1: SNMPV2 SNMP is “A protocol that enables a management station to configure, monitor, and receive trap (alarm) messages from network devices”. ... html#v2) SNMP2 is "an open standard that defines a way for network managers to obtain specific performance and configuration information from a software agent resident on a remote-network device. ... Race, April 20, 2000) When SNMP was first implemented in 1988, it was intended to create an effective network management system that used the minimum computer hardware resources, because both memory and CPU time were expensive. ... SNMP2 or Simple Network Management Protocol Version 2 brought many changes to the then current standard of network management protocols on TCP/IP-based networks. ... RFC1445 talks about the “Administrative Model for version 2 of the Simple Network Management Protocol” while 1446 reflects on Security Issues concerning SNMP2. ... Message stream modification is the in-transit modification of messages sent by authorised parties, and disclosure addresses the danger of messages being re-ordered, delayed or replayed to an extent that is greater than can occur during the natural operation of a sub network service. ... MIB A MIB or Management information base is a database or directory that contains all the names of the information resources a network management program might need. ... Many hardware and software developers define their own MIBs allowing them to be compiled in a network management system. ... The only other way is to packet sniff every packet which, on a switching network is extremely inefficient. ... I have created a MIB for a modem on a network. ... It is an Internet protocol enabling a diskless workstation to find its own IP address and that of a BOOTP server on a network. ... DHCP stands for Dynamic Host Configuration Protocol. It enables a system on a network to extract its configuration information from a server (commonly known as a DHCP server). ... Both BOOTP and DHCP are used to reduce the work needed to manage large IP Networks The main difference between BOOTP and DHCP is that BOOTP was designed for manual pre-configuration of the host information in a server database, while DHCP allows for the dynamic allocation of network addresses and configurations to newly attached hosts (or hosts which are turned on and added to the network). For example the information about a system need not be entered into the servers database prior to the system being added to the network. |
