There is always the possilbility of overloading a trunk when doing a
span or if you configure the span wrong.
However, if you do this carefully there is rarely a problem.

> Hello,

> A quick question regarding span:  I have multiple switches

> If I have multiple vlans configured on the switches, but I am 
> trunking them

> on switch E to recieve all traffic from all switches?  I was

> the trunk port.
> My concern then is with overloading the trunk.  Is there a 
> standard way to
