HOL Blocking
You use this selection to prevent a packet from being forwarded
to a blocking or blocked port. For example, a blocking or blocked
port can be one that is receiving too many packets.
To select a value, click the circle next it. Possible values are:
❑ Enabled - Indicates HOL blocking is turned on. Packets sent from
this port are not forwarded to a blocked port. This is the default.
❑ Disabled - Indicated HOL blocking is turned off. Packets sent from
this port are forwarded to a blocked port.
Override Priority
You use this selection to determine packet priority.
For more information about this feature, refer to Class of Service
Overview on page 320.
To select a value, click the circle next it. Possible values are:
❑ None - Indicated that no override priority is assigned to incoming
packets. Instead, the port forwards packets according to the
priority embedded in the packet. This is the default.
❑ Low - Indicates low priority has been assigned to the port. As a
result, all tagged and untagged packets are sent to the low
priority queue.
