Networking Requirements
As shown in
0/0/24 is connected to host 1; Ethernet 0/0/5 is connected to host 2. To monitor incoming traffic
on Ethernet 0/0/1, interface mirroring is configured on the Switch. Configure Ethernet 0/0/1 as
a mirrored port, and Ethernet 0/0/24 connected to host 1 as an observing port. Enable host 1 to
receive incoming traffic from Ethernet 0/0/1.
At present, host 2 needs to receive incoming traffic from Ethernet 0/0/1. Therefore, the observing
port needs to switch from Ethernet 0/0/24 to Ethernet 0/0/5.

Delete the mirrored port Ethernet 0/0/1.
Set Ethernet 0/0/5 instead of Ethernet 0/0/24 as the observing port.
Reset Ethernet 0/0/1 as a mirrored port.
Type and number of the new observing port, that is, Ethernet 0/0/5
Check the configurations on the current observing port and mirrored port.
# Run the display port-mirroring command to check the configurations on the current
