1. The 8000 and auto max 4000 speed configurations are available only for the 8-Gbps modules.
2. The default speed on 48-port and 24-port 4-Gbps modules is 4000. The defualt speed on 48-port and 24-port 8-Gbps modules is 8000.
The default speed on the 4/44-port 8-Gbps module is auto max 4000.
Use the show interface command to verify the port speed configuration for an interface on a 4-Gbps or
8-Gbps Fibre Channel switching module.

Chapter 3 Configuring Fibre Channel Interfaces
Purpose
Configures the port speed in megabits per
second. Valid values are 1000, 2000, 4000 and
auto. The auto parameter enables autosensing
on the interface.
1
(8-Gbps modules only ) Configures the port
speed in megabits per second to 8-Gbps. Valid
values are 1000, 2000, 4000, 8000 and auto.
The auto parameter enables autosensing on the
interface.
On 4-Gbps modules, configures autosensing for
the interface with 4 Gbps of bandwidth
reserved.
On 8-Gbps modules, configures autosensing for
the interface with 8 Gbps of bandwidth
2
reserved.
Configures autosensing with a maximum of
2 Gbps of bandwidth reserved.
1
(8-Gbps modules only ) Configures autosensing
with a maximum of 4Gbps of bandwidth
reserved.
2
Reverts to the default speed for the interface
(auto).
