•
Jumbo Frames—Provides a dialog box for enabling and disabling Jumbo IP frames. When
disabled, the MTU is 1,500 bytes; when enabled, the maximum MTU is 9,000 bytes. When
other
is selected, the MTU size can be set between 1,000 and 9,000 bytes.
•
TCP Window Size—Contains a dialog box that provides three options for TCP window size:
8,192, 16, 384, and 32,768 bytes. The default is 32,768.
•
Window Scaling—Contains a dialog box that provides for enabling and disabling TCP window
scaling. The default is Disabled. When enabled, the Window Scaling Factor is used.
•
Window Scaling Factor—Contains a dialog box that provides six options for TCP window
scaling: 0, 1, 2, 3, 4, 5, 6, and 7.
•
TCP Port Number—Provides a dialog box that enables the user to define the destination TCP
port number used by the FCIP route. This port number must be the same on both routers
participating in the FCIP route (local and remote routers must be using same port number).
The default port number used by FCIP is 3225.
•
GigE Port Speed—Provides a dialog box that contains four options for the GigE port speed:
Auto, 10, 100, and 1000: The port speed rate is Auto.
•
Port Speed Mode—Provides a dialog box that contains three options for the link rate mode:
Auto, half duplex, and full duplex. This dialog box is available only when the GigE port speed
is set to something other than Auto.
•
GigE Port Flow Control—Provides a dialog box for enabling and disabling GigE port flow
control. The default is Enabled. This dialog box is available only when the GigE port speed
is set to something other than Auto.
•
VLAN Enabled—Provides a dialog box for enabling and disabling VLAN support. The default
is Disabled.
•
VLAN ID—Provides a dialog box that enables the user to define the VLAN ID. This dialog box
is available only when VLAN is enabled. The VLAN ID must be the same on both gateways
participating in the FCIP route (local and remote gateways must be using same VLAN ID) and
the Ethernet switches.
•
VLAN Priority—Provides a dialog box that contains eight options for the VLAN priority: 0
through 7. This dialog box is available only when VLAN is Enabled.
•
FCIP SW Compression—Provides a dialog box for enabling and disabling FCIP compression.
The default is Disabled.
•
Bandwidth (Mbit/sec)—Provides a dialog box that enables the user to define the maximum
bandwidth (in Mb/s) used by the GigE port during transmits. The range of values supported
is 1 to 1,000 Mb/s. This setting enables the user to limit the bandwidth used by each FCIP
route so as not to consume all the available link bandwidth. For example, if the slowest link
in the WAN being used is a DS-3 link, then the maximum available bandwidth is 45 Mb/s.
To limit the FCIP route to 33% of the overall link bandwidth, set the bandwidth to 15 Mb/s
(see
).
HP P9000 and P6000 Continuous Access replication solution requires dedicated bandwidth
for the intersite link. If other applications share the intersite link, some method of QoS must
be used to ensure that the replication application has uncontested access to the allocated
bandwidth.
