Find switch port and domain ID using portID

May be applicable only to Brocade!!

System logs always show portIDs while referring to and SAN device error and it is aways tough to find the port details,

For eg:-

syslog: fctl: [ID 517869 kern. warning ] WARNING: fp(0)::PLOGI to 0x91300 failed. state=a reason=3. (Restricted Access Project)

In this error shows portID as 0x91300, so to determine which port is referring to, follow below process

NportID 0x91300


Start separating from left side… like 0x/9/13/00 <--
These values are in Hex format, to identify the actual port we have to Convert all Hex numbers to decimal.

9 when converted to decimal it is 9
When 13 is converted to decimal it is 19

So the device is connected to switch port 19 of domain id 9.

Another example:-

NportID 0xc91c00

Again start separating from left…
0x/c9/1c/00 <-

c9 is 201 in decimal and 1c is 28 in decimal. So device is connected to port 28 in domain ID 201.



But it seems this is only applicable to B series switches.
