PACP on Cisco ASR

HI I am trying to do some packet captures on a tunnel interface and wanted to ask a few questions.

 

Details are as follows:

 

Router : ASR1002-X

Version: "bootflash:asr1002x-universalk9.03.10.05.S.153-3.S5-ext.SPA.bin"

 

Was trying to run packet capture based on the information as on the below link.

 

https://supportforums.cisco.com/document/29616/utilizing-new-packet-capture-feature

 

But wanted to check if this is capable to get the desired information if the interface of interest is a Tunnel interface with details as below?

 

Tunnel537 is up, line protocol is up
  Hardware is Tunnel
  Description: ### VPN Tunnel  ###
  Internet address is xxx.xxx.xxx.xxx/30
  MTU 17868 bytes, BW 100 Kbit/sec, DLY 50000 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation TUNNEL, loopback not set
  Keepalive set (10 sec), retries 3
  Tunnel source aaa.aaa.aaa.aaa (Loopback53), destination bbb.bbb.bbb.bbb
   Tunnel Subblocks:
      src-track:
         Tunnel537 source tracking subblock associated with Loopback53
          Set of tunnels with source Loopback53, 2 members (includes iterators), on interface <OK>
  Tunnel protocol/transport GRE/IP
    Key disabled, sequencing disabled
    Checksumming of packets disabled
  Tunnel TTL 255, Fast tunneling enabled
  Tunnel transport MTU 1476 bytes
  Tunnel transmit bandwidth 8000 (kbps)
  Tunnel receive bandwidth 8000 (kbps)
  Last input never, output never, output hang never
  Last clearing of "show interface" counters 1d09h
  Input queue: 0/375/0/0 (size/max/drops/flushes); Total output drops: 0
  Queueing strategy: fifo
  Output queue: 0/0 (size/max)
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     2771530 packets input, 619976946 bytes, 0 no buffer
     Received 0 broadcasts (0 IP multicasts)
     0 runts, 0 giants, 0 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     2770869 packets output, 618159879 bytes, 0 underruns
     0 output errors, 0 collisions, 0 interface resets
     0 unknown protocol drops
     0 output buffer failures, 0 output buffers swapped out
 

also when  trying to run the following command it is not being accepted. Any reason why or a workaround for it?

 

Router#monitor capture point ip ?
% Unrecognized command

 

Any advise on this will be much appreciated.

 

Thanks in advance.
