clear tcp-forwarding connections
Syntax
clear tcp-forwarding connections listening-port listening-port-number listening-address ipv4-listening-address source-address source-ipv4-address source-port source-port-number routing-instance routing-instance-name
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.
|
| 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.
|
| routing-instance routing-instance-name | Name of the routing instance for the TCP mapping. |
