You can install filters that will act on traffic destined for the switch itself, such as ICMP Echo Requests (ping) and SNMP messages. If the associated action is to drop the traffic, you can lock yourself out of the switch.
However, traffic destined for the switch and received through a port on the base unit of a stack is not dropped even if filters targeting the traffic are installed and drop has been specified. This behavior prevents you from completely isolating yourself from the switch. Consider this behavior when you configure filters and when you allocate ports for the purposes of configuring and or monitoring the switch.
Also, please note when configuring IP filters, the Address Mask specifies the portion of the address used to determine if that particular packet meets your filter criteria.
