allocation for these queues. In WFQ mode, frame latency as delay bound is not assured.
Best Effort (BE)
- In BE mode, a queue only receives bandwidth when none of the other classes have any
traffic. It is used for non-essential traffic because there are no assurances about BE performance.

Note
: If the
Delay Sensitive Application
option of any active profile is enabled, an error message will be
displayed when you try to set the rate control. It is recommended to try to activate another profile with the
Delay
Sensitive Application
option disabled because the
Delay Bound
scheduling operation conflicts with rate
control operation of the switch. It is recommended to use Profiles 3, 4, 7 or 8 as the activity profiles for rate
control operation because they are
Delay Sensitive Application
disabled.
You can configure the WFQ setting in each profile and select four of the ten profiles to be the active profiles for
the scheduling operation on each port of the switch. For the profile setting, first select either
Megabit Ports
Profile
or
Gigabit Ports Profile
.
Megabit Profile
Use the
Megabit Profile
to define the content of QoS profiles. There are ten different profiles, but only four of
them can be the active profiles for QoS control in the switch. The
01 profile
contains the following settings:
Port Using This Profile
– Lists the ports using this profile.
Strict Priority
- Displays the Strict Priority setting of this profile.
Delay Sensitive Application
- Displays the Delay Bound setting of the profile.
Profile Name
– Displays the name of this profile which can be modified.
Profile Status
– Displays status of this profile (active or non-active) which can be modified. The 2600M
