SNMPv3 messages contain a msgMaxSize field that specified the maximum supported message size (in bytes). This field's value is usually set automatically by the component, but you may also specify the value directly by using the MsgMaxSize configuration option. For instance, the following code snippet sets the maximum supported message size to 4096 bytes:

snmpmgr.Config("MsgMaxSize=4096"); snmpmgr.SendGetNextRequest();

The MsgMaxSize configuration option is present in the following components:

• SNMPAgent
• SNMPTCPAgent
• SNMPMgr
• SNMPTCPMgr
