how to reference a swap-only ZFS pool

I have created a pool of two mirrored disks that will be used as
additinal swap.

root on rudun-epiccache101:/opt/local/scripts# zpool status
[...]
 pool: swappool
state: ONLINE
scan: none requested
config:

       NAME        STATE     READ WRITE CKSUM
       swappool    ONLINE       0     0     0
         c1t0d0s1  ONLINE       0     0     0
         c1t1d0s1  ONLINE       0     0     0

errors: No known data errors
root on rudun-epiccache101:/opt/local/scripts#

My question is, what is the device name?  I want to add it as an
additional swap area (swap -a) but I have not been able to figure out
what the entry is for the swap command to reference this new pool.

What would the name of this pool be for the purposes of swap -a?
