clear security flow session conn-tag
Syntax
clear security flow session conn-tag conn-tag-id-number
Description
Clear the session identified by the session connection (conn-tag) identification tag.
The flow session connection tag allows you to add a filter to further distinguish GRSP tunneling protocol, user plane (GTP-U) flow sessions, and Stream Control Transmission Protocol (SCTP) flow sessions.
Options
| conn-tag | A 32-bit connection tag that uniquely identifies the GPRS tunneling protocol, user plane (GTP-U) and the Stream Control Transmission Protocol (STCP) sessions. The connection tag for GTP-U is the tunnel endpoint identifier (TEID) and for SCTP is the vTag. The connection ID remains 0 if the connection tag is not used by the sessions. You can configure the system to include the session connection tag tuple to identify GTP-U session and SCTP sessions by adding the session connection tag to the standard six tuples that identify a session. The system determines the DCP for GTP-U/SCTP by hashing the session connection tag. The central point architecture distributes GTP-U traffic handled by a gateway GPRS support node (GGSN) and SGSN pair on all SPUs by switching to tunnel endpoint identifier (TEID)-based hash distribution. To handle load-balancing issues, tag-based hash distribution is used to ensure even distribution of SCTP traffic from different associations among all SPUs. (The connection tag for GTP-U is the TEID and for SCTP is the vTag.)
