these contracts to limit individual traffic flows.

n
A classification policy where certain frames are grouped together
n
A bandwidth policy specifying usage limitations to be applied to these frames
N
OTE

At any given time, up to 1024 contracts can be created for a single Alteon AD4 or
Alteon 184 Web switch.
Internet
1. Client buys a contract
