ExtremeWare Error Message Decoder 277
Cannot Create VLAN
ERROR: Cannot create vlan "IN_test" Hardware resource is not available (2/0)
Software Version
ExtremeWare 7.0.0 and later
Hardware Version
All
Explanation
This error appears on the console when you are trying to create a VLAN and the hardware resource is
not available. You need hardware resources to create a VLAN. For example, you need some PTAGs
(OTPs) to hold all ports in the vlan for broadcast and unknown destination packets. When these PTAGs
are not available, this type of error message is displayed.
In the above message, the first number (2) indicates that it failed to allocate PTAG block (1=PTAG
index), and the second number (0) is the corresponding slot+1.
In addition, an error message is added to the log. In the above example, the message looks similar to
the following:
"ERROR: Bridge create failed due to OTP block allocation failure (%d)"
In this case, the switch is constantly reporting out of PTAG blocks in the log:
08/29/2003 12:30.16 <WARN:HW> tNetTask: Reached maximum otp block allocation for MSM-B
08/29/2003 12:30.16 <WARN:HW> tNetTask: Reached maximum otp block allocation for slot 2

Action
Find out why this particular switch is running out of PTAG block. For example, is it as a result of a
virus attack?
