5.3.5 SNMP Configuration Commands

Command	Purpose
snmp-server	Enable the SNMP agent. The first snmp-serverglobal configuration
	command enables SNMP.
snmp-server engineID {local engineid-	Set Engine ID for local or remote devices. The remote engine ID is
stringremote host-ip-address [udp-port	used to create users that can send SNMPv3 traps.
port-number]engineid-string}
snmp-server view view-name subtree	Define the SNMP server view. Currently, the SNMP subtree can only
[subtree-mask] [included excluded]	adopt numbered form. That is, “1.3.6.1.2.1” is valid but “mib-2” is
	invalid. The subtree-maskuses colon-separated hex digits, such as
	“FF:A0”.
snmp-server group group-name{v1	Set SNMP views. The default read-view is “all,” and the default write-
v2c v3 [auth noauth ]} [read	view and notify-view are “none”.
read-view] [write write-view] [notify
notify-view] [access access-list]
snmp-server user user-name group-	Define SNMP server users. (Currently creating “v1v2” users and the
name [remote host-ip-address [udp-	“sha”(SHA1) algorithm are not supported)
port port-number]] { v3 [auth {md5}

snmp-server enable traps [ duplicate-	Enable SNMP traps. Supported trap types are authentication,
ip snmp station-move]	duplicate-ip, and station-move.
snmp-server trap-timeout seconds	Define how often to resend trap messages. The range is 1–1000. The
	default is 30 seconds.
snmp-server queue-length length	Set the message queue length for each trap-host. The range is 1–
	1000. The default is 10.
snmp-server contact text	Set the system contact string.
snmp-server location text	Set the system location string.

5.4 Configuring Spanning Tree

The Spanning Tree Protocol (STP) is part of the IEEE 802.1D standard. It provides for a redundant network without the redundant traffic through closed paths. For example, in a network with redundant path but without spanning tree protocol, the same message is broadcast through multiple paths, leading to an unending packet-passing cycle. This in turn causes a great amount of extra network traffic, leading to network downtime. The STP reduces a network traffic, with multiple, redundant connections, to one in which all points are connected, but where there is only one path between any two points (the connections span the entire network, and the paths are branched).
