This chapter has looked at various issues that network administrators may encounter when implementing SNMP. Many of these problems arise as the result of vendor-specific implementations that may be incompatible with each other. The wise network manager will be alert for these incompatibilities so that the challenge of managing complex internetworks can be simplified.
