Embedded packet capture on ASR1000

[rjuchta]

Hi,

I'm trying to use EPC on ASR1001 running IOS-XE 3.4, and it won't work.

Configuration commands are accepted by the router, but there are no packets in the capture buffer.

config:

ip access-list extended icmpdump

permit icmp any any

monitor capture buffer buf1

monitor capture buffer buf1 max-size 1508

monitor capture buffer buf1 filter access-list icmpdump

monitor capture point ip cef cap1 all both

monitor capture point associate cap1 buf1

monitor capture point start cap1

after some time, and some icmp passed through the router:

asr1k#show monitor capture buffer all parameters

Capture buffer cap1 (circular buffer)

Buffer Size : 1048576 bytes, Max Element Size : 1508 bytes, Packets : 0

Allow-nth-pak : 0, Duration : 0 (seconds), Max packets : 0, pps : 0

Associated Capture Points:

Name : cap1, Status : Active

Configuration:

monitor capture buffer cap1 size 1024 max-size 1508 circular

monitor capture point associate cap1 buf1

monitor capture buffer cap1 filter access-list icmpdump

In release notes for IOS-XE, in the 2.5 section, there is a statement that EPC is not supported on ASR1k. Is it true also for newer versions of IOS-XR?

Thanks and regards,

WM

You may check the following URL for IOS XE -

http://www.cisco.com/en/US/docs/ios-xml/ios/epc/configuration/xe-3s/asr1000/nm-packet-capture-xe.html

Not all versions of IOS-XE image supports EPC on ASR1K. This feature would be included in XE3.7.

Commands aren't depreciated on rest of the versions of image on ASR so you can still see commands like "monitor capture buffer" & "monitor capture point".
