Long Distance Fabric
When this mode is set to 1, ISLs in a fabric can be up to 100 km long. The exact distance
level is determined by the per-port configuration on the E_Ports of each ISL. Both E_Ports
in an ISL must be configured to run the same long-distance level; otherwise, the fabric will
be segmented.
An Extended Fabrics license is required to set this mode.
BB Credit
The buffer-to-buffer (BB) credit represents the number of buffers available to attached
devices for frame receipt. The range of allowed values varies depending on other system
settings (see Unicast-only Operation). Refer to the Fabric OS Administrator's Guide for
more information on platform-specific BB Credit limitations.
Insistent Domain ID Mode
When this mode is set, the switch attempts to acquire from the fabric the domain number
programmed in its "Switch Fabric Settings." If the operation fails, the switch will segment
from the fabric. You must disable the switch before configuring this parameter.
Disable Default PortName
When this mode is set, the switch does not generate a default port name.
Display FDMI Host Name
When this mode is set, the switch displays the FDMI Host name. By default this feature is in
OFF state.
Dynamic Portname
When enabled, this feature dynamically assigns port name with various fields such as switch
name, port type, port index, and alias name. Dynamic Portname and Display FDMI Host
Name features are mutually exclusive.
Remote Fosexec feature
The remote fosexec configuration is bi-directional. The configuration is checked when
sending any fosexec request to a remote switch and also when receiving the request from a
remote switch. Thus, both the sending and receiving switched must be configured with
fosexec ON. By default remote fosexec feature is in OFF state.
High Integrity Fabric Mode
Disables or enables the system to check for FMS mode and all existing HIF parameters
present in the switch. By default this feature is in OFF state.
Edge hold time
Configures the maximum time a frame can wait after it is received on the ingress port and
before it is delivered to the egress port. If the frame waits in the egress buffer for more than
the configured hold time, the switch drops the frame, replenishes sender's credit, and
increments the counters er_tx_c3_timeout and er_rx_c3_timeout on the TX and RX ports
respectively. The frame-timeout indicates a slow draining or a congestion or bottleneck in
the fabric. Decreasing hold time on the edge switches may reduce frame drop counts in the
core switches. This parameter is stored persistently in the configuration file. You can
configure edge hold time on both default and logical switch.
