(Optional) Configuring the Aging Time of the ECA Session Flow Table

(Optional) Configuring the Aging Time of the ECA Session Flow Table

Context

After the ECA function is configured, ECA sessions and flow entries are generated for traffic that enters the switch. The ECA session flow entries are aged out after a certain period, and the aged flow entries are sent to the CIS server as metadata. Currently, ECA session flow entries can be aged out using the following methods: active flow aging and inactive flow aging.

Active flows refer to traffic that persists for a long period and is stable. Flow statistics are output periodically for active flows that are aged out. Inactive flows refer to traffic that persists for a short period. Once the traffic stops, the device immediately outputs flow statistics to save memory space.

Procedure

  • Configure the aging time of active flows of an ECA session.
    1. Run system-view

      The system view is displayed.

    2. Run engine session timeout active time

      The aging time of active flows of the ECA session is configured.

      By default, the aging time of active flows of an ECA session is 60 seconds.

  • Configure the aging time of inactive flows of an ECA session.
    1. Run system-view

      The system view is displayed.

    2. Run engine session timeout inactive time

      The aging time of inactive flows of the ECA session is configured.

      By default, the aging time of inactive flows of an ECA session is 15 seconds.
