Address status table.
It supports the query and setting of status of the local address pool.
It does not support the query and setting of status of the remote address pool for the following reasons:
1. The status of the remote address pool cannot be set.
2. The remote and local address pools map different status tables, with different indexes.
3. The remote address pool is managed by the remote equipment, rather than the local equipment. The local equipment displays only the approximate status of the remote address pool.
