SAN Priority CoS
CoS provides eight levels to accommodate more than one traffic class of
SAN, LAN, and IPC, with one of the classes used for SAN traffic. This set-
ting shows the persistent value for priority-encoded port packets: 0–7. The
default value is 5. The SAN CoS setting affects the connection only when
connected to a peer that is not configured with DCBX.
When connected to a DCBX-enabled peer, the port CoS value is automati-
cally set to value specified in the port CoS TLV, regardless of this parame-
ter setting.
When not connected to a DCBX-enabled peer, or before receiving a port
CoS value, the port CoS TLV is based on this parameter setting.
Priority Txt Mode
Specifies the priority mode for data transfer as one of the following:
„
Strict
disables the other bandwidth settings. When other settings are
disabled, the switch negotiates the port bandwidth according to settings
configured on that switch.
„
Bandwidth
specifies that a percent of bandwidth to SAN traffic uses
the SAN bandwidth percent scale. Bandwidth sets the percentage of
the number of gigabytes per second (Gbps) transmission speed of the
port's capacity to SAN versus LAN traffic. The
Bandwidth
mode guar-
antees a transmission rate for SAN traffic over the port.
SAN Bandwidth Per-
cent
If the
Priority Txt Mode
is set to
Bandwidth
, this value indicates the
SAN versus LAN percent setting.
SAN Unused Bw To LAN Enabled
specifies that unused bandwidth allocated for SAN traffic is real-
located to LAN traffic when necessary.
SAN Unused Bw To SAN Enabled
specifies that unused bandwidth allocated for LAN traffic is real-
located to SAN traffic when necessary.
