Support for speed Auto-Negotiate
Auto-negotiate is supported. However, HP recommends that the por t speed for E_Ports (for Interswitch
links, or ISLs) be set to a specicportspeed(1Gb /sec, 2Gb/sec,or4GB/sec as appropriate for the
speed of the Directors or Edge Switches being connected) instead of to Negotiate.Usingaspecic
port speed decreases the time for a fabric build in response to some perturbation event in the fabric.
Similarly,
setting a specic p ort speed for N_Ports also de creases fabric build time. However, setting a
specicpo
rt speed for N_Ports is not required.
There ar e a few older HBA devices that do not always succeed in logging in to a switch port when
the por t speed is set for auto-negotiate.
Workaround
If an older HBA has d ifculty logging into a switch port that has its port speed congured as Negotiate,
congure that port speed to 1Gb/sec, 2Gb/sec,or4GB/sec according to the operation speed of the
HBA connected to that port.
