Lab – Configuring SNMP

____________________________________________________________________________________

For example, the description for OID 1.3.6.1.6.3.1.1.5.4 is a linkUp trap signifies that the SNMP entity,

acting in an agent role, has detected that the ifOperStatus object for one of its communication links left

the down state and transitioned into some other state (but not into the notPresent state). This other state

is indicated by the included value of ifOperStatus.

Reflection

1. What are some of the potential benefits of monitoring a network with SNMP?

_______________________________________________________________________________________

Answers will vary, but students may point to the ability of SNMP as an open and cross platform protocol to

work with many different devices including host computers on the network. SNMP benefits a network

administrator whose job it is to monitor the status and configuration of network hosts across the entire

network.

2. Why is it preferable to solely use read-only access when working with SNMPv2?

_______________________________________________________________________________________

Because SNMPv2 supports only unencrypted community strings, using read-write access would be a greater

security risk.
