Command History
Usage Guidelines
You can specify a range of interfaces by issuing a command with the following example format:
interface
space
fc1/1
space
-
space
5
space
,
space
fc2/5
space
-
space
7
Tip
The
shutdown
or
no shutdown
command for the FCIP or iSCSI interfaces is automatically issued when
you change the MTU size—you do not need to explicitly issue this command.
You must perform the
fcrxbbcredit extended enable
command in configuration mode to use the
switchport fcrxbbcredit extended
command in interface configuration submode to enable extended
BB_credits on a Fibre Channel interface.
The port speed on an interface, combined with the rate mode, determines the amount of shared resources
available to the ports in the port group. Especially in the case of dedicated rate mode, the port group
resources are reserved even though the bandwidth is not used. For example, if an interface is configured
for autosensing (
auto
), then 4 Gbps of bandwidth is reserved even though the maximum operating speed
is 2 Gbps. For the same interface, if autosensing with a maximum speed of 2 Gbps (
auto max 2000
) is
configured, then only 2 Gbps of bandwidth is reserved and the unused 2 Gbps is shared with the other
interface in the port group.
