ASR901 port mirroring

[Sanjeewa Dharmasiri]

ASR901 does not support port mirrioring as in other platforms.

Insted we can use following for port mirroring.

901(config)#service internal

901(config)#^Z

901#

901#test mirror 1 both 11

Here gig 0/0 interface will be mirrored to gig 0/10 interface.

What is the use of service internal command. It is not documented anywhere.....

Hello Sanjeewa

service internal command is a hidden command that is used to enable certain command line features as may be used by Cisco engineer to check some internal commands of the platform while troubleshooting. This command enable internal platform level commands. Like for example on 7600/6500 platform, you can perform ELAM capture (used to capture a single packet either on DFC or SP ) only after you enable "service internal".

Hope this answers your question. Let me know if you have any further questions.

Hi Vinijain,

Thanks a lot. Well explained.

In my case on ASR901 how can i disable the port mirroring. Even under the "sh int gig 0/10" it does not say that port is mirrored.

Hello Sanjeewa

you can disable the port-mirroring using the none option:

test mirror 1 none

This will disable the mirroring.
