    Release Information

    Statement introduced in Junos OS Release 12.2 for the QFX Series.

    Description

    Set the maximum number of FCoE initialization protocol (FIP) session logins permitted on a Node device.

    On a QFX3500 switch, max-login-sessions-per-node sets the maximum FIP session login limit for all of the FC fabrics configured on the device. The combined number of FIP sessions on all FC fabrics on the device should not exceed this limit.

    On a QFabric system, max-login-sessions-per-node globally sets the maximum FIP session login limit for each QFabric system Node device in the QFabric system. For example, if you set the Node limit to 2000 login sessions, then each QFabric Node device supports up to 2000 FIP login sessions. The total configured maximum number of login sessions of all of the FC fabrics on a Node device should not exceed the Node session limit.

    Note: The maximum number of FIP sessions a Node device can support depends on whether the FCoE-FC gateway FC fabrics on that Node device are trusted or untrusted. When an FC fabric is untrusted, FIP snooping filter overhead restricts the number of FIP sessions. When an FC fabric is trusted (fcoe-trusted is configured on the fabric), FIP snooping filters are not created for the sessions, so the number of sessions can be increased.

    On a QFabric system, if a Node device has untrusted FC fabrics, each untrusted FC fabric on that Node device is limited to 376 login sessions regardless of the Node session limit. (This is the combined total of all VN2VF_Port and VN2VN_Port sessions on the system.) For example, a Node device that has two untrusted FC fabrics and no trusted FC fabrics can have a maximum of 752 sessions even if the QFabric maximum Node limit is 2500 sessions.

    Note: FIP login session limits configured at the FC fabric level or at the FC fabric interface level might limit a Node device to fewer total sessions than the configured Node limit.

    Options

    max-login-sessions-per-node—Maximum number of FIP login sessions.

    Range: 128 through 2500

    Default: 2500 sessions (note that untrusted fabrics on Node devices still have a maximum limit of 376 sessions)
