Deployment with FCIP extension switches

Deployment with FCIP extension switches

Encryption switches may be deployed in configurations that use extension switches or extension
blades within a DCX, DCX-4S or 48000 chassis to enable long distance connections.
shows an encryption switch deployment in a Fibre Channel over IP (FCIP) configuration. Refer to the
Fabric OS Administrator's Guide for information about creating FCIP configurations.
When an encryption switch is deployed with an extension switch or blade in the same chassis or
fabric, the encryption switch can use the FCIP functionality provided by the extension switch.
In Figure
FCIP link. If the encryption services are enabled for the host and the remote target, the encryption
switch can take clear text from the host and send cipher text over the FCIP link. For FCIP on the
extension switch, this traffic is same as rest of the FCIP traffic between any two FCIP end points.
The traffic is encrypted traffic. FCIP provides a data compression option. Data compression should
not be enabled on the FCIP link. If compression is enabled on FCIP link, then encrypted traffic going
through FCIP compression may not provide the best compression ratio.
