Specifying The Persistent Session Rule; Clearing Sessions Manually; Configuring Session Logging; Enabling Session Logging - HP A6600 Configuration Manual

To enable checksum verification for protocol packets:
To do...
1. Enter system view.
2. Enable checksum verification.

Specifying the persistent session rule

set some sessions that have specific characteristics as persistent sessions. The aging time of a persistent
session does not vary with the session state transitions, and a persistent session is not removed because
no packets match it. A persistent session can be specified with an aging time that is longer than those of
common sessions, or it can be configured to be a permanent connection, which is cleared only when the
session initiator or responder sends a request to close it or when you clear it manually.
Set the persistent session criteria by specifying a basic or advanced ACL. All sessions permitted by the
ACL are persistent sessions. For more information, see ACL and QoS Configuration Guide.
To specify the persistent session rule:
To do...

Clearing sessions manually

sessions.

Configuring session logging

Session logs help track information about user access, IP address translation, and traffic, and they can
be sent to the log server or exported to the information center in flow log format. Session logs can help
network administrators in security auditing.
