Intrepid® 6140 Director Installation and Service Manual
Installation Tasks
• OpenTrunking - Use the OpenTrunking View to optimize ISL
bandwidth. The feature monitors data rates (congestion and
BB_Credit starvation) through multiple ISLs and load balances
traffic (from congested to uncongested links) accordingly.
• Preferredpath-Use the PreferredPathViewto specify and
configure one or more ISL data paths between multiple fabric
elements. At each fabric element, a preferred path consists of a
source port, exit port, and destination Domain_ID.
• Port fencing - Use the Port Fencing View to minimize ISLs that
bounce (repeatedly attempt to establish a connection), causing
disruptive fabric rebuilds. Fencing defines a bounce threshold
that when reached, automatically blocks the disruptive E_Port.
To configure optional ISL performance features, refer to the McDATA
EFCM Basic Edition User Manual (620-000240) for instructions.
If no additional options or features are to be configured,go to Ta sk 2 1:
Cable Fibre Channel Ports.
Task 5: Configure Director Network Information (Optional)
The director is delivered with default network addresses as follows:
• MAC address - The media access control (MAC) address is
programmedinto FLASHmemoryon the controlprocessor(CTP)
card at manufacture. The MAC address is unique for each
product and should not be changed.
• IP address - The default IP address is 10.1.1.10.Ifmultiple
products are installed on the same LAN, each product (and the
management server) must have a unique IP address.
NOTE: If multiple products and themanagement server are delivered in
a Fabricenter equipment cabinet, all devices are configured with unique
IP addresses that do not require change. The addresses require change
only if multiple cabinets are LAN-connected.
• Subnetmask - The default subnet mask is 255.0.0.0.Ifthedirector
is installed on a complex public LAN with one or more routers,
theaddressmayrequirechange.
• Gateway address - The default gateway address is 0.0.0.0.Ifthe
director is installed on a public LAN, the gateway address must
be changed to the address of the corporate intranet local router.
