'sh idb' works on most recent code, too:

gsr5#sh idb 

Maximum number of Software IDBs 8192.  In use 615.

                       HWIDBs     SWIDBs
Active                    613        613
Inactive                    2          2
Total IDBs                615        615
Size each (bytes)        5840       2592
Total bytes           3591600    1594080


Every intefaces takes a SWIDB; physical interfaces (and tunnels, for
whatever reason) take a HWIDB as well.
