Interface status on Cisco CAt 4500 switch as source-monitoring

[gmaccisco1]

Hi Guys,

I have assigned int gi3/45 on my Cisco 4500 CAT switch as the monitoring port as source and gi3/47 as the destination.

I see this:

GigabitEthernet3/45 is up, line protocol is down (monitoring)

but on the destination port both are up, interface up and line protocol up.

is this natural? I have executed the no shutdown on gi3/45 but it still says down!

is this normal? or there is a problem? i have monitoring on my edge switch CAT 3560 but both are saying UP/UP, shouldn't this be the same since both swithces are running Cisco IOS.

Please respond. I appreciate your input and thanks in advance.

this interface (g 3/45) is the destination, it says so "monitoring", it normal for the "destination" or "monitoring" port to be up/down coz it's not sending or receiving traffic destined to it, only the mirrored packets from the source port. can you post the "show monitor session #"?

It is normal on the newer IOS switches , don't worry about it .

It's normal. To enable normal traffic to the destination-port use the command:

monitor session 1 destination int ingress untagged vlan
