RE: RSPAN

Hi , thanks for the reply
no , i have configured the vlan as a remote , what am looking for is should we use the vlan filter in order to make the monitor the vlans of concern ? i know we are already mentioned the vlans we want in the monitor line but checking if the filter needed ?
and in the intermediate switches we do not need to configure the monitor sessions right ? because what we care about is the trunks in between

Thanks
