I'm actually monitoring some interfaces on our core switch and want to send these mirror traffic to another switch.
The setup looks like below.
Aruba core ( 3810) :
interface Trk 1-10 > monitor all both mirror 1
mirror 1 port 2/B2
Aruba access switch (2540):
interface 52 monitor
mirror-port 18 > connect to IDS
However STP blocks LAN connections, the setup looks like this.
Core 1/ A1 & 2/A1 > Access Switch (Port 49 & 50) - Used for LAN connections
Core 2/B2 > Access Switch Port 52 - Used for Port mirroring
See logs:
Core:
I 06/17/24 11:32:04 00077 ports: ST2-CMDR: port 2/B2 is now off-line
I 06/17/24 11:31:33 00076 ports: ST2-CMDR: port 2/B2 is now on-line
I 06/17/24 11:31:32 00435 ports: ST2-CMDR: port 2/B2 is Blocked by STP
Access:
I 06/16/24 10:50:58 00076 ports: port 52 is now on-line
I 06/16/24 10:50:58 00435 ports: port 50 is Blocked by STP
I 06/16/24 10:50:58 00435 ports: port 49 is Blocked by STP
As i can see it shutdown the ports used for LAN connections.
Can someone shed some light.
