iRule for mac address identification

I am using the iRule statement "set macparta [[lindex [split $radname1 "-" ] 5 ]" for the calling station id (containing the MAC address) field is (with as separator “-“) But if the MAC addressfield is with as separator “:“) . How will be my iRule statement to work in both case .

 

For E.g; if the Calling-Station-Id mac address format is

 

Calling-Station-Id = "2C-1F-23-45-3B-1E" Calling-Station-Id = "dc:9b:9c:cd:43:e5"

    Use log local0 in order to identify how it would look. 

    set macparta [[lindex [split $radname1 "-" ] 5 ]

    Assuming, $radname1 refers to the Calling-Station-Id, the answer would be 1E for MAC address with - and it won't work for MAC address with :

    Hi,

    you can convert the calling station id with the expected format:

    set radname1 "2C:1F:23:45:3B:1E"
set radname1 [string map {: -} $radname1] 

set macparta [[lindex [split $radname1 "-" ] 5 ]

    Hi Sukumar,

    how about using a 

    [split]
    command which splits the input MAC on both the ":" or "-" char at the same time...

    set radname1 "2C:1F-23:45-3B:1E"
set macparta [[lindex [split $radname1 ":-" ] 5 ]

    Cheers, Kai
