clear tcp-forwarding connections

Syntax

Description

Clear all TCP connections, all connections associated with a specific listening port/listening address combination, or a single connection pair represented by a specific source address/source port combination. For either combination, you can optionally specify a routing instance. If you do not specify a routing instance, the default routing instance is assumed. This command enables you to disconnect TCP port forwarding connections that are not behaving properly.

Options

listening-address ipv4-listening-address

IPv4 address that is part of a listening port/listening address combination. The listening address is one on the BNG that external management systems or remote devices must use when attempting to trigger connections on the listening port. You must also specify a listening port.

listening-port port-number

Port number that is part of a listening port/listening address combination. The listening port is one that the BNG monitors for connections to be triggered by external management systems or remote devices.

  • Range: 8000 through 8031

source-address source-ipv4-address

Source address of the triggering entity—the remote device or external management system—that appear in the TCP header.

source-port source-port-number

Source port of the triggering entity—the remote device or external management system—that appear in the TCP header.

  • Range: 1 through 65,535
