Open Caveats

When you globally disable IEEE 802.1x on the switch by using the no dot1x system-auth-control
global configuration command, some interface level configuration commands, including the dot1x
timeout and dot1x mac-auth-bypass commands, become unavailable.
The workaround is to enable the dot1x system-auth-control global configuration command before
you attempt to configure interface level IEEE 802.1x parameters.

When you enter the no speed interface configuration command, the Ethernet interface speed does
not return to its default setting. This affects interfaces Gi0/17 to Gi0/20, Gi0/23, and Gi0/24. This
does not affect interfaces Gi0/21 and Gi0/22.
The workaround is either to enter the speed interface configuration command auto keyword to
change the interface speed to the default setting or to explicitly set the speed.

If you enter the test cable-diagnostics tdr privileged EXEC command on the dual-media interfaces
Gi0/23 and Gi0/24, the Ethernet interface that is being tested shuts down and then comes back up.
There is no workaround.

When dynamic ARP inspection is configured on a VLAN, and the ARP traffic on a port in the VLAN
is within the configured rate limit, the port might go into an error-disabled state.
The workaround is to configure the burst interval to more than 1 second.

When you change the media-type interface configuration command keyword from auto to rj45, the
interface loses its link and does not recover it. This only affects the dual-media Ethernet interfaces
Gi0/17 to Gi0/20, Gi0/23, and Gi0/24 when the interface is physically linked with the RJ-45
interface; it does not affect interfaces Gi0/21 or Gi0/22. This occurs when you have explicitly
configured the duplex interface configuration command or the the speed interface configuration
command to a keyword other than auto.
The workaround is to reconfigure the Ethernet interface for media-type rj45. Set the speed and
duplex to auto. Then change the media-type to auto-select. Speed and duplex configurations are
not permitted if the media-type is set to auto-select.

The Ethernet interface fa0 loses and regains its link because of a DHCP IP address timeout. This
situation exists when the HP Onboard Administrator acts as the DHCP server and provides the
IP address to the fa0 interface. This occurs when using the clear arp-cache privileged EXEC
command to explicitly clear the ARP table.
The workaround is to add a static ARP table entry for the DHCP server (in this case, the Onboard
Administrator) to the switch and to increase the lease time of the DHCP IP address on the server.

Fiber optic small form-factor plugable (SFP) modules do not establish a link when you configure
the Ethernet interfaces with the speed nonegotiate interface configuration command.
The workaround is to remove the speed nonegotiate setting for the Ethernet interface that has the
fiber SFP installed. This configuration has to be done on the link partner device as well.
