Forward Error Correction
Forward Error Correction (FEC) allows recovering of error bits in a 10 Gbps or a 16 Gbps data stream.
This feature is enabled by default on all ISLs and ICLs of 10 Gbps and 16 Gbps FC platforms. FEC is
supported in Access Gateway mode.
To configure FEC for an FC port or ICL port, perform the following steps.
1. Select the Port Admin tab from the Switch Explorer window.
2. Select View > Advanced.
3. Select a port from the FC Ports Explorer or ICL Ports Explorer.
4. Select Forward Error Correction > Enable or Disable from the Actions list.
One of the following FEC statuses is displayed in the General tab of the FC port or ICL port:
• Enabled (Active) - FEC is enabled on a port and the configuration is Active.
• Enabled (Inactive) - FEC is enabled on a port and the configuration is Inactive.
• Disabled - FEC is not enabled on a port.
• NA - FEC is not supported.
5. Click OK on the warning message that prompts enabling or disabling of Forward Error Connection
results in traffic disruption.
In-Band Management
In-Band Management is designed to allow the management of the switch through gigabit Ethernet ports.
This allows a management station located on the WAN side of the FCIP platform to communicate with
the control processor for management tasks, such as launching Web Tools, SNMP polling, SNMP traps,
trouble shooting, and configuration. To provide this communication, new interfaces have been added to
the control processor that have an external IP address, allowing IP connectivity through the port
processor to the control processor.
The In-Band Management interface is protocol-independent, so any traffic destined for these In-Band
Management interfaces is passed through the distribution point to the control processor. It is then
handled on the control processor, according to the rules set forth for the normal management interface
and following any security rules that may be in place on the control processor.
To provide redundancy, there is one In-Band Management interface per gigabit Ethernet port. This
allows the management station on the WAN side of the network to have multiple addresses with which
to reach that switch, and allow redundancy in the event one of the gigabit Ethernet ports becomes
unreachable for any reason.
Communication is handled through external addresses that are configured independently for each In-
Band Management interface. The In-Band Management interfaces share the routing table on the control
processor. This is separate from the routing table for each gigabit Ethernet port that exists. Because of
this, there are certain limits to the addresses that are allowed, and the routes that are allowed for the In-
Band Management interfaces and route entries.
In-Band Management is supported on the Brocade 7800 and Brocade FX8-24. In-Band Management is
not supported in Fabric OS v7.3.0. Only one IP interface entry can be configured per gigabit Ethernet
port.
