Block State/Left Time (s)

PBA port block entry state for NAT port allocation, including Active, Inactive, Query, and the time left for a port block that is in the Active or Query state.

• Active–When an internal subscriber initiates a NAT request, a port block is allocated from the pool, and the status is set to Active. When there is a subsequent request from the same subscriber, a port is allocated from the existing Active block.

• Inactive–When there is a request from an internal subscriber who had previously had a port allocated from this port block, but the time on the Active port block has expired or the ports are used up, the port block status changes from Active to Inactive.

• InactiveB–When a chassis cluster is in active/passive mode, and a port block is created on the active node, the status for the synced port block on the backup node is InactiveB.

• Query–When no ports are used in an Active port block, the status changes from Active to Query.
