Port mirroring on Nortel BayStack 460-PWR

Dear all,

I am designing a network using the BS460 as power switches.

I need to put a sniffer on a specified port on the switch to monitor

the traffic on my network.

Is the BS460-PWR capable of doing many-to-one port mirroring, i.e. can

i mirror 23 ports on a single one?

It is stated clearly that the 450's can do it, but I could find nothing

regarding the 460's.

Thanks in advance
