Support for speed Auto-Negotiate

Auto-negotiate is supported. However, HP recommends that the port speed for E_Ports (for Interswitch

links, or ISLs) be set to a speciﬁc port speed (1Gb/sec, 2Gb/sec, or 4GB/sec as appropriate for the

speed of the Directors or Edge Switches being connected) instead of to Negotiate. Using a speciﬁc

port speed decreases the time for a fabric build in response to some perturbation event in the fabric.

Similarly, setting a speciﬁc port speed for N_Ports also decreases fabric build time. However, setting a

speciﬁc port speed for N_Ports is not required.

There are a few older HBA devices that do not always succeed in logging in to a switch port when

the port speed is set for auto-negotiate.

Workaround

If an older HBA has difﬁculty logging into a switch port that has its port speed conﬁgured as Negotiate,

conﬁgure that port speed to 1Gb/sec, 2Gb/sec, or 4GB/sec according to the operation speed of the

HBA connected to that port.

Issue

The RADIUS key is allowed

to be blank (zero characters).

The ﬁrmware should not accept a blank

key.

Attempts to activate a large zone set through OSMS

when CT authentication is enabled occasionally

may not be successful.

Determining current version

This section describes how to determine the current version of ﬁrmware for an Edge Switch or Director

using the HAFM, HAFM Basic, or CLI.

Using HAFM

To determine the current version using HAFM:

Open the Element Manager for the Edge Switch or Director.

Select Product from the menu bar.

A menu appears.

Select Properties.

The ﬁrmware version appears in this dialog box.

Workaround

The ﬁrmware should not accept a blank key.The RADIUS

key should not be blank. Ensure that you enter the key

correctly.

Temporarily disable CT authentication, and then

activate the zone set.
