Configuration considerations
To provide higher network availability and forwarding performance, use the two switches to
•
construct an IRF fabric.
To meet the security requirements of Company B and the operation data space requirement of
•
Company A, configure two MDCs across chassis on the IRF fabric to provide a virtually separate
access device and a separate operation data space for each company. An MDC across chassis
provides higher network availability.
To restrict the disk space usage of Company A, specify a disk space percentage for MDC A.
•
Leave MDC B to use the default disk space.
•
• Assign an IP address to the management Ethernet interfaces of the IRF fabric and the MDCs and
enable the Telnet service on the interfaces to allow remote IRF fabric management and remote MDC
management.
IMPORTANT:
The default MDC has two IRF links. Make sure at least one IRF link is operating correctly during the
configuration process. Otherwise, the IRF fabric splits.
