There is no equivalent single command I'm aware of. Moreover, some of the kernel tunables are handled differently on Solaris 10 and newer. They can be dynamically adjusted instead of being fixed at boot time and can also be different depending on their consumer (eg: project or zone).
Are there specific metrics you would like to check/monitor ?

dbc_max_pct(5) OBSOLETED dbc_max_pct(5)
NAME
dbc_max_pct, dbc_min_pct, bufcache_max_pct, bufpages, nbuf - OBSOLETED kernel tunable parameter
DESCRIPTION
These tunables have been obsoleted and removed. Do not make any changes to these tunables, as they have no effect on the kernel.
Use the file cache tunables and (see filecache_max(5)).
In previous releases, the tunables and were used to set limits to the dynamic buffer cache, and the tunables and were used for tuning the
buffer cache when a static cache was desired.
This release of HP-UX offers improved file caching technology and improved physical memory control associated to caching file I/O data.
The number of tunable parameters used to control file caching memory usage is reduced from five to two, and previous usability issues are
addressed.
Restrictions on Changing
These tunables should not be modified. Attempting to tune any of the obsolete buffer cache tunables, or results in an error.
Use the tunables and to set limits on the file cache. Note that, on a any given system, the optimum values of these two new tunables are
not necessarily equivalent to the optimum values of the obsolete buffer cache tunable values in the older systems. You should first deter-
mine if the new default values yield acceptable performance on your system, before attempting to change the values of the new file cache
tunables.
