I have 2 links to 2 different departments switch with an up link of 10mb. I want to guarantee that both departments get at least 5mb, but can use part of the other 5mb that not in use. Is this possible?
Thanks
Steve

Should be easy for interface egress traffic.
Very, very difficult for interface ingress. If possible, ingress is often best dealt with on other side of link's egress.
PS:
Likely next question might be how.
For egress if, physical inteface is 10 Mbps
something like:
class-map match-any deptA
match . . .
class-map match-any deptB
match . . .
policy-map 5050
class deptA
bandwidth percent 49
class deptB
bandwidth percent 49
interface (10mbps)
service-policy output 5050

Joseph,
I assume this just limits them to 5mb each. I was wondering if there was a way to guarantee 5mb each, but allow them to use the other 5mb if it not being used by the other department.
example
dept a is using 2mb so dept b could use up to 8mb, but if dept a needs more it would take to back from dept b.

No, CBWFQ bandwidth statements provide a minimum guarantee. If there's unused bandwidth, it may be used. I.e. each dept is guaranteed half the bandwidth, but if the other dept. was only using 25%, the other dept. could use 75%.
PS:
Oh, if you wondering why 49% rather than 50%, I think the IOS version you're likely will have might need 1% for class-default.
