The robots.txt works fine however Google's crawlers still have problem
while accessing our website.

Did you submit a sitemap for your site?
If so, just in case the network unreachable
was a temporary problem,
can you resubmit the sitemap?

Okay...

are you concerned about the Errors, or the fact that it keeps saying
unreachable?

.

Some of those URLs don't exist
(http://www.sunyopt.edu/admissions/finaid.shtml)

.

Maybe you are having server issues?
Can you check your logs and see if there was a problem whilst G tried
to crawl it?

It would appear that googlebot does have a problem with your
robots.txt.

have you used the robots.txt verifier in the webmaster tools?

I tried to submit a sitemap many times but it gave me the following
Sitemap errors and warnings

Details         -       Network unreachable: robots.txt unreachable
We were unable to crawl your Sitemap because we found a robots.txt
file at the root of your site but were unable to download it. Please
ensure that it is accessible or remove it completely.

Are you talking about the "Analyze robots.txt" under Tools?

It shows

Our concern is that Googlebot cannot reach us. Doing a search using
"suny optometry" on google, the search result only shows our index
page while it shows many of other pages before. What can we do to fix
the network issue so google can crawl the entire website?

Check if your site is blocking Googlebot
in any way, via .htaccess or firewall, etc.

It's more than likely an issue on the server not accepting Google's
attempts to reach the robots.txt periodically.  I cannot replicate it
right now, tried it several times bot with a Google IP and useragent,
no referer, no java enabled etc.  The site appears to be on a
dedicated server, or at least not a very populated one so I'd work
through the logs on the dates given above when they could not reach
robots.txt and see if anything sticks out, high load, server down,
etc.

It could hurt you if you don't figure out what is causing Google to
not be able to reach the server, it seems to be sporadic which is kind
of weird.  I don't know your hosting situation but if done through a
3rd party, I'd get them involved and tell them that Googlebot is
having trouble reaching the site.  Perhaps they have some sort of
robot trap running for over-agressive bots that Google got caught up
in.

Perhaps a Googler can look into the exact response a bit more, but
like I said I cannot replicate the errors at the moment.

Hi sunyopt and welcome to the groups!

JLH is pretty much spot-on, it does look like the Googlebot is having
trouble reaching your site in general. It would be good to check with
whoever is responsible for the hosting to make sure that there is
nothing blocking the Googlebot's access.

Hope it helps!
John
