Brocade Web Tools Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 101)

NOTE
To configure a port as an EX_Port, the switch must be capable of supporting FCR or FCIP features.
The EX_Port option is disabled in the wizard if the switch does not meet these requirements.
Speed
The FC Port Configuration tab provides the option to set the port speed. To set the speed, the EGM
license must be enabled on the switch. Otherwise, access to port speed configuration is denied and an
error message displays. You can configure 2G, 4G, 8G, or 16G port speed or set the port to auto-
negotiate the highest possible port speed. The Auto Max options are displayed only when you set the
port speed as auto-negotiation and these options allow you to set the speed limit the port can auto-
negotiate. The following Auto Max speed levels are supported:
• Auto Max 2G
• Auto Max 4G
• Auto Max 8G
• Auto Max 16G
NOTE
The Auto Max 16G option is supported for the 16G Capable FC ports only. Auto Max configuration is
optional.
Long distance mode
Port long distance configurations can be performed in the Switch Admin Extended Fabric tab if the
link is used over long distances. To configure the long-distance settings, the EGM license must be
enabled on the switch. Otherwise, access to port long distance configuration feature is denied and an
error message displays. For information about long-distance mode settings, refer to
Administering
Extended Fabrics on page 187.
The EGM license is required only for 8 Gbps platforms, such as the following:
• Encryption Switch
• 300, 5300, and 5100 switches
• Brocade VA-40FC
• Brocade 7800
For non-8 Gbps platforms, all functionality is available without the EGM license.
Ingress rate limit
From Fabric OS v7.2.0, the ingress rate limit can be configured without an Adaptive Networking (AN)
license.
Ingress rate limiting restricts the speed of traffic from a particular device to the switch port, allowing
latency-sensitive applications to share the storage resources alongside throughput-intensive
applications. Ingress rate limiting delays the return of BB credits to the external device. By limiting the
throughput on the ingress side of a port, existing congestion can be removed or avoided.
The implication is as follows:
