Configuring
The LCM command format for Remote Port Mirroring is:
Local ATX (in reference to the diagnostic port)
mirror remote off
off - to turn remote port mirroring off
mirror remote to port# oversized
port# - the diagnostic port on the local ATX
oversized - discard or truncate; what to do with oversized
packets
Remote ATX (in reference to the diagnostic port)
mirror port-range off
off - to turn remote port mirroring off
mirror port-range to Ipaddr
port-range - range of mirrored ports on remote ATX
Ipaddr - ip address of the local ATX where the diagnostic port
resides
Note: Both ATX LAN Switch’s have to have port mirroring turned off in
order to fully disable the remote port mirroring function.
3.11.1 Types of Media and Framing
Mirrored and diagnostic ports have no restrictions and can be any
of the ATX LAN Switch’s interfaces, Token Ring, Ethernet, Fast
Ethernet or FDDI. However, it is recommended that the diagnostic
port and mirrored ports are of the same media type and framing.
This is because in an intermixed mode, due to the differences in the
physical layers, mirrored packets may be translated or dropped.
For example, when an 802.5 packet is mirrored out to an 802.3
interface, the MAC addresses are translated (big endian to little
endian) and the length field is added to the original frame.
