1) no STP.  Switches that do not support STP, forward the BPDUs.  The 2724 forwards STP BPDUs. 2) 2724 has a very low performace CPU.  Pings response time will not consistant.  Especially on a live network where the CPU is being hit with Broadcast traffic.  
Hi there.   The Software on the 2724 is limited that's very obvious but there are 2 things that I'd like to understand.   1) No STP settings at all, does it support STP at all? If not does it forward BPDUs? 2) When pinging the management interface the ping is all over the place, from 1ms to 150, totally random.   Thanks Simon
