To create the VLAN, clear the Mobility Domain config-
uration from the switch, create the VLAN, then con-
figure the Mobility Domain again. 

The set port poe 

port-list

 disable command 

might not disable PoE. (17624)

On rare occasions (one in about 20 times), the 

set 

port poe

 

port-list

 

disable

 command might not dis-

able PoE on the specified ports. 

To determine whether PoE has really been disabled, 
type the 

display port poe 

command. If the Draw 

field lists a number instead of 

off

, PoE is still enabled. 

Try entering the 

set port poe

 

port-list

 

enable

 com-

mand, followed by the 

set port poe

 

port-list

 

disable

 

command. 

Display of WX4400 serial number for licensing 
contains only the last 6 digits. (18398)

Port group causes harmless error message to be 
displayed during startup. (18333) 

If a port group is created and assigned to a VLAN, an 
error message is displayed while the switch is booting 
up whenever the switch is reset or power cycled. 
Below is an example of the error message. This 
applies to both MX1200 and MX4400.

Example:

Starting supervisor 3.0.3.0_110304_WX1200 ...

.......SPAN Nov 05 07:01:44.073135 ERROR 
SPAN_VLAN_ERR: span_port_change, port= 0 does 
not exist 

This message can be safely ignored.

Harmless 

botched superblock

 messages during 

startup. (18564)

When you boot the switch, the startup messages 
include lines such as the following:

Checking for botched superblock 
upgrades:msysioctl() 0x40386d02

...

msysioctl() 0x40386d02

done.

These messages do not indicate a problem and can be 
safely ignored.

Switching and Port Issues

Autonegotiation with a 3Com switch that 
supports Smart Auto-Sensing may result in a 
10Mbps link. (18325)

If a WX1200 switch is attached to a 3Com switch that 
supports Smart Auto-Sensing, and autonegotiation is 
enabled at both ends of the link, the connection may 
be down-rated to a 10 MBPs full-duplex link on initial 
boot-up of the WX1200.

To resolve this issue, restrict the advertised capabilities 
of the link partner on the SAS-enabled switch or dis-
able SAS on the switch.

devices between WX switches in a Mobility
