This can be blocked only at L3 level, i.e, on VLAN interface. Since access switch port works in L2, it dosin't understand L3 protocols.

Depending on the IPX encapsulation, you can try this (tested on a Cat 3550) :

- create a "MAC extended ACL" filtering on the 8139 EtherType

- apply this ACL on the access ports

This should block "Ethernet2" and "SNAP" encapsulated IPX packets without altering other protocols.
