Forward Error Correction

Displaying compression ratio
16 Gbps capable FC platforms that support compression and encryption, also provide the
compression ratio. Under Port Admin tab, the FC Ports tab and the General tab of a port display
one of the following values for the Compression Ratio:
Forward Error Correction
Forward Error Correction (FEC) allows recovering of error bits in a 10Gbps or a 16Gbps data stream.
This feature is enabled by default on all ISLs and ICLs of 10Gbps and 16Gbps FC platforms.
Forward error correction is supported in Access Gateway mode.
To configure forward error correction for an FC port or ICL port, perform the following steps.
1. Select 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 forward error correction 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 enabledGigEgigabit Ethernet 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.
<<numeric value>> Compression is enabled for a port.
- - Compression is supported but not configured.
N/A Compression is not supported.
