Functions Overview

Functions Overview

TCP-MIB is defined in RFC 4022. With TCP-MIB, you can obtain related TCP parameters such as the retransmission algorithm and retransmission delay and statistics about TCP packets such as the number of received and received packets by performing the Get or Get Next operation. In addition, TCP-MIB allows you to perform the Set operation on tcpConnectionState and tcpConnState so as to close a specific connection.

TCP-MIB contains the following contents:

  • Simple variables: are used to describe TCP operation parameters and save statistics.

  • tcpConnectionTable: is used to describe TCP connections. It stores the network information (such as the address and port number) and current status of each TCP connection.

  • tcpListenerTable: is used to describe all TCP listening endpoints of the system.

Besides the preceding contents, TCP-MIB of the current version contains tcpConnTable defined in RFC 1213. tcpConnTable has been divided into tcpConnectionTable and tcpListenerTable. tcpConnTable is not recommended in RFC 4022. Considering forward compatibility, tcpConnTable is reserved and the Set operation can be performed on any object in tcpConnTable.
