Configuring Ports on a Switch
Up to eight mirroring filters and one monitor port can be configured. After a port has been specified as
a monitor port, it cannot be used for any other function.
NOTE
Frames that contain errors are not mirrored.
The mirrored port always transmits tagged frames. The default port tag will be added to any untagged
packets as they are mirrored. This allows you to mirror multiple ports or VLANs to a mirror port, while
preserving the ability of a single protocol analyzer to track and differentiate traffic within a broadcast
domain (VLAN) and across broadcast domains (for example, across VLANs when routing).
NOTE
For optimum performance, mirror three or fewer ports at any given time.
• Mirror ports and monitor ports should both be confined to the following ranges: 1:1-1:24, 1:25-1:48,
1:49-1:52.
