flow-session

Syntax

Hierarchy Level

Description

Specifies the number of flow sessions that user logical system administrators and primary logical system administrators configure for their logical systems if the security profile is bound to the logical systems.

The primary administrator:

  • uses security profiles to provision logical systems with resources.

  • binds security profiles to user logical systems and the primary logical system.

  • can configure more than one security profile, specifying different amounts of resource allocations in various profiles.

Only the primary administrator can create security profiles and bind them to logical systems.

Options

maximum amount

A maximum allowed quota. If a logical system requires more of a resource than its reserved amount allows, it can utilize resources configured for the global maximum amount if they are available—that is, if they are not allocated to other logical systems. The maximum allowed quota specifies the portion of the free global resources that the logical system can use. The maximum allowed quota does not guarantee that the amount specified for the resource in the security profile is available. Logical systems compete for global resources.

  • Range: 0 through 1000000

reserved amount

A reserved quota that guarantees that the resource amount specified is always available to the logical system.

  • Default: 0

Note:

An IPv6 session consumes twice the memory of an IPv4 session. Therefore the number of sessions available for IPv6 is half the reserved and maximum quotas configured for the flow session resource in a security profile. Use the vty command show usp flow resource usage cp-session to check flow session usage.
