Thanks for the quick reply. I am running 12.2(18)SXF10a , "test mcast ltl
index " doesn't seem to work.However in this case I could find the interface
number since I know where the was CSS connected. Can you guide me find the
index number someotherway.?


Here is what I did to find out.

bbr00m1#*show tcam interface gigabitEthernet 1/47 qos type1 arp detail*
* Global Defaults not shared
--------------------------------------------------------------
T     - V(Value) M(Mask) R(Result)
A     - ARP Packet
R     - RARP Packet
X     - XTAG
--------------------------------------------------------------
*Interface: 46 *  label: 511   lookup_type: 1  ##### *DEST_INDEX  [19] =
0x2E*  is *Interface: 46 *
protocol: ARP   packet-type: 3
+-+-----+--+-+------------+---------------+
|T|Index|AR|X| Dest Node  |  Source Node  |
+-+-----+--+-+------------+---------------+
 V 36839 -- 0      0      0 <-
 M 36845 -- 0      0      0 <-
 R rslt: 0           <-
