From my corporate office, I've got a remote office connected via a vlan
on a trunked port over 10mbps. I run QOS over this link for voice. That
works all fine and dandy.
What I'm rtying to do now is tag SQL traffic with af32 so it has higher
priority over other traffic (like http, smb, etc). I have an
application tha truns on the remote site and calls the SQL server at the
corporate office. The 10mbs link has tons of free bandwidth, but I'm
having major issues with the application.
The corporate end has a Cat6513 running CatOS (don't go running scared
because you don't know CatOS, just talk to me in IOS if you need to),
and the remote site a 3560. On the remote site, I got traffic destined
for port 1433 tagged as af32 by applying a service policy to the input
on the ports where computers are connected (you can't apply a service
policy to the output of a port, or else I would have done it on the
trunked link to the other office)
On the 6513, I can't get source port 1433 traffic to tag properly. I
created an ACL tagging af32 to traffic matching "tcp any eq 1433 any"
and "any any eq 1433". I applied this acl to the port that I'm using to
trunk the remote site, that didn't work. I applied it to the VLAN being
used and that didn't work. Note that I can't apply this ACL to the VLAN
on output, only input. The switch just won't allow it.
I have not tried applying the ACL to the port hte SQL server is on,
because this would make all SQL traffic throught he entire switch af32,
and I don't want to do that. I only want SQL traffic going across the
trunked link tagged.
Any advice?
