has a matrix of merging fabrics with tolerant and absent policies.
Management interface security
You can secure an Ethernet management interface between two Brocade switches or
enterprise-class platforms by implementing IPsec and IKE policies to create a tunnel that protects
traffic flows. The tunnel has at each end a Brocade switch or enterprise-class platform. There may
be routers, gateways, and firewalls in between the two ends.
ATTENTION
Enabling secure IPsec tunnels does not provide IPsec protection for traffic flows on the external
management interfaces of intelligent blades in a chassis, nor does it support protection of traffic
flows on FCIP interfaces.
Internet Protocol security (IPsec) is a framework of open standards that ensures private and secure
communications over Internet Protocol (IP) networks through the use of cryptographic security
services. The goal of IPsec is to provide the following capabilities:
•
Authentication — Ensures that the sending and receiving end-users and devices are known and
trusted by one another.
•
Data Integrity — Confirms that the data received was in fact the data transmitted.
•
Data Confidentiality — Protects the user data being transmitted, such as utilizing encryption to
avoid sending data in clear text.
