FLOW-CONTROL Use this to enable flow control on a full duplex port or enable
the auto-negotiation process to determine whether the port
and device connected can operate using flow control.
When you disable the flow control setting of 10 Mbps or 100 Mbps
ports, the change will not take effect until the switch is reset or powered
off and on again.
HOLB-P Use this to release traffic overload scenarios by early packet
drop.
PORT-PRI Use this to change the priority settings for the port.
A Round Robin chain ensures that low priority frames will not
be starved.
• regular– all frames received on this port will have a regular
priority, unless the frame is tagged with high priority.
• high – forces all frames received on this port to have a high
priority.
The Cajun P120 treats all the received BPDUs as high priority
packets - regardless of the Port-Priority and to the Port Tagging
Mode
. Unknown frames are always set to low priority.
PORT-VLAN Use this to set ports to a VLAN or show which ports are on
which VLAN.
VLAN-MODE Use this to set the port VLAN tagging mode. There are two
available modes:
• Tagging - In this mode all packets are transmitted tagged
with their VLAN and Priority in the 802.1Q format (in SW
Ver. 1.0, packets belonging to the Port VLAN are transmitted
untagged). The port is “BindToAll” VLANs within the Cajun
P120 switch.
Use this mode when connecting 802.1Q-compliant devices
to such a port.
• No Tagging - In this mode all packets are transmitted
untagged. The port is “bindTo” only the Port VLAN.
Use this mode when connecting legacy or 802.1Q priority-
tagged devices.
In both modes, received tagged packets are mapped to their
VLAN in the tag, while untagged or priority-tagged (VIDEO)
packets are mapped to the Port VLAN.
