SPANNING on a CATALYST with CAT OS

Hello.

I would like to perform a spanning

of a full-duplex 100 Mb interface towards

2 different interfaces, to avoid the frames loss problem, due to the fact

that 200 Mbit ( 100Mb in one direction and 100 Mb in the opposite direction)

of traffic cannot be mirrored to a 100 mbit link of the spanning-port.

e.g.;

(suppose the original traffic in the 2/5 port,

and the port 2/8 and 2/9 the 2 destination mirroring ports )

If I try to give the commands:

set span 2/5 2/8 rx

set span 2/5 2/9 tx

only the last command is accepted.

While it's possible to give the command:

set span 2/5 2/8 both

but in this way the port 2/8 is filled with 200Mb of traffic, of course loosing packets.

Does some workaround exist to solve this?

thanks

Re: SPANNING on a CATALYST with CAT OS

The only workaround, since the CLI will not allow you to point only to a single SPAN destination port, is to copy traffic to a gigabit port, that can handle the 200M of traffic.
