Unknown command in Monitor session setup

Forum

I am working at a customer site this morning.  I was configuring a monitor session to use the sniffer when I noticed in an existing session the following:

monitor session 1 source interface Gi3/9 , Gi3/43
monitor session 1 filter packet-type good rx
monitor session 1 destination interface Gi3/48
monitor session 2 source interface Gi4/33 , Gi4/44
monitor session 2 filter packet-type good rx
monitor session 2 destination interface Gi4/7

I do not know what the highlighted commands mean or do, and have not used them before.  I am even not sure why they are showing up now, as I did not configure them.

Thanks for any insight

Kevin

Re: Unknown command in Monitor session setup

Here's a link that explains what the command does:

I'm not sure why it's showing up in the config if you didn't change the default though.

I change the default all the time when I set up SPAN sessions.  I had just never seent that in the config before.  i am quite certain it did not used to say that.  At some point, it has started populating that in whenever I am configuring the SPAN sessions.

Thanks for your response and link.
