McDATA UltraNet Edge 3000 User Guide
Network Design
10/100 Ethernet Switches & Routers
• 10/100 Mbps Ethernet interface switches and routers that are
directly connected to the data path are required to be configured
for full duplex and 100Mbps. Auto Negotiation is not supported
on these switches or routers.
NOTE: Cisco routers must always be set manually for 100Mbps, Full Duplex.
Gigabit Ethernet Switches & Routers
• It is preferred that Gigabit Ethernet interface switches and routers
that are directly connected to the data path be configured for
Auto Negotiate. Auto Negotiate is the default setting in UltraNet
ConfigManager. Configuring the UltraNet Edge 3000 to Full
Duplex in UltraNet ConfigManager is only allowed for devices
directly connected that do not support Auto Negotiate.
NOTE: The UltraNet Edge 3000 Gigabit Ethernet interface must remain at the
default setting of Auto Negotiate when connected to a Cisco router.
Ethernet Hubs
• Ethernet Hubs are not supported in the data path.
Fibre Channel Switches
NOTE: The UltraNet Edge 3000 contains an internal Fibre Channel switch
application (FCSW) and when configured for F_port, an external Fibre
Channel switch is not necessary unless more than two Fibre Channel ports
are needed.
• McDATA supports F_port using the McDATA internal Fibre
Channel Switch (FCSW) application over an Ethernet or ATM
WAN interface.
• McDATA supports E_port extension and Device Extension
(FC/SCSI Tape Pipelining) using Brocade and McData Fibre
Channel switches over an Ethernet or ATM WAN interface.
• The FCSW application allows remotely connected N_ports to
login and see other N_ports via this application using the
standards compliant services.
