monitoring traffic cisco 2600 router

  • Follow


cisco 2651XM router
IOS: c2600-adventerprisek9-mz.124-15.T9.bin
WIC-1-ADSL card fitted (Dialer0)

I'm using the monitor command on the above router to keep an eye on the 
traffic on another server thus:
monitor session 1 source interface Fa1/0 (server connected here)
monitor session 1 destination interface Fa1/1 (PC running wireshark 
connected here)

It works well but I'd like to do the same thing where the source is the 
Dialer0 port but the config won't allow it - it only seems to permit a 
FastEthernet port. Is there a way or another command that will enable me to 
monitor all traffic at the (source) adsl port and output it to a 
(destination) FastEthernet port?

Not a direct answer to your question, but have you considered using a 
netflow probe on the Dialer of Zeroness?

Hey, SPAN on an ISR is limited IIRC. Depending on your config, you
might be able to use RITE: http://www.cisco.com/en/US/docs/ios/12_4t/12_4t1=
1/ht_rawip.html
.. It works like SPAN, but SRC has to be an interface running IP, and
DST as to be an Ethernet. If you need any help setting this up, give
me a shout.

Wow - not heard of that. Docs say only on some platforms.

12.4(20)T and later has an additional packet capture facility.

According to www.cisco.com/go/fn
Embedded Packet Capture is on the current router platforms
however not apparently the 2651XM:(

thanks for your feedback and yes I do need help in troubleshooting this. I
wanted the Dialer0 as source and F0/0 as the destination output and I did
the steps at the above address you gave and but I'm not getting any dialer0
traffic from the destination port Fa0/0.
the commands I did were:
router(config)#ip traffic-export profile my_rite
router(conf-rite)#int dialer0
router(conf-rite)#bidirectional
router(conf-rite)#mac-address 0090.27FC.756F
router(conf-rite)#exit
router(config)#int f0/0
router(config-if)#ip traffic-export apply my_rite
..Oct  1 21:27:44.326: %RITE-5-ACTIVATE: Activated IP traffic export on
interface  FastEthernet0/0

the only thing I'm not sure about is the mac address. I used the
mac-address of the NIC in my PC - this is the receiving device. That's
correct isn't it?

here's what the 'show run' gave after putting in the above commands:
<snip>
ip traffic-export profile my_rite
  interface Dialer0
  bidirectional
  mac-address 0090.27fc.756f
<snip>
interface FastEthernet0/0
 ip address 192.168.0.1 255.255.255.0
 ip traffic-export apply my_rite
 duplex auto
 speed auto
<snip>
interface Dialer0
 ip address negotiated previous
 ip access-group 104 out
 no ip redirects
 no ip proxy-arp
 ip nat outside
 ip virtual-reassembly
 encapsulation ppp
 dialer pool 1
 dialer idle-timeout 0
 dialer persistent
 dialer-group 1
 no cdp enable
 ppp authentication chap callin
 ppp chap hostname my username
 ppp chap password 0 password

thanks for any further advice.

oops and damn.
typical that a few minutes after my above post I realised I had the monitor
and destination ports configured round the wrong way. The command:
show ip traffic-export int f0/0
showed up this error, so I did the config again and now it appears to be 
working well and I can see detailed Dialer0 traffic in wireshark on the PC.
thanks very much for your help.
