❑ High - Indicates high priority has been assigned to the port. As a
result, all tagged and untagged packets are sent to the high
priority queue.
Status
You use this selection to enable or disable a port. When disabled,
a port does not receive or transmit frames.
For example, you may want to disable a port and prevent packets
from being forwarded if a problem occurs with the node or cable
connected to the port. Once the problem has been fixed, you can
enable the port again to resume normal operation. You can also
disable an unused port to secure it from unauthorized
connections.
To select a value, click the circle next it. Possible values are:
❑ Enabled - The port receives and forwards packets. This is the
default setting.
❑ Disabled - The port does not receive or forward packets.
Broadcast Filter
You use this selection to protect a port from a deluge of packets
caused by a broadcast storm. Enabling the broadcast filter
parameter on a port causes the port to discard all ingress
broadcast frames.
To select a value, click the circle next it. Possible values are:
❑ Enabled - The port discards all ingress broadcast frames.
❑ Disabled - The port accepts all ingress broadcast frames. This is the
default setting.
Back Pressure
You can use this selection only if the port or ports you specified
are operating at half-duplex mode. When you specify that a port
is in this mode and it has a packet that is pending transmission,
then the software suspends the JAM pattern before sending the
packet. After the packet is sent, the JAM pattern resumes.
To select a value, click the circle next it. Possible values are:
❑ Enabled - Indicates back pressure is activated on this port. When
the port is receiving too many packets, the port sends a signal to
the end node to stop sending information.
❑ Disabled - Indicates back pressure is not activated on this port.
When the port is receiving too many packets, the port does not
send a signal to the end node to stop sending information. This is
the default.
