Viewing TCP global information
View TCP and UDP information to view the current configuration.
Before you begin
Change the VRF instance as required to view TCP global information on a specific VRF instance. Not all parameters are configurable on non-default VRFs.
About this task
The fields on the TCP global tab provide information about the handshake (SYN) configuration and the maximum number of TCP connections you can create on your system.
When you initiate a TCP connection, both end points send handshake information to create the channel.
The retransmission algorithm and fields display the configured timeout value and minimum and maximum retransmission times that your system uses to terminate a connection attempt that falls outside your specified parameters.
Procedure
- In the navigation pane, expand the folders
- Click TCP/UDP.
- Click the TCP Globals tab.
TCP Global field descriptions
Use the data in the following table to use the TCP Globals tab.
Name | Description |
|---|---|
RtoAlgorithm | Determines the timeout value used for retransmitting unacknowledged octets. |
RtoMin | Displays the minimum time (in milliseconds) permitted by a TCP implementation for the retransmission timeout. |
RtoMax | Displays the maximum time (in milliseconds) permitted by a TCP implementation for the retransmission timeout. |
MaxConn | Displays the maximum connections for the device. |
