A system for sharing peripheral component interconnect express (PCIe) devices across multiple host servers is disclosed. In some embodiments, a switch includes a plurality of hosts associated with a plurality of hierarchies, one or more endpoints associated with one or more of the plurality of hierarchies, and a switch communicatively connectable to the plurality of hosts and the one or more endpoints. The switch is configured to: receive a transaction layer packet (TLP); determine a policy group identifier based on parsing and processing the TLP; perform packet forward matching based on the policy group identifier and destination fields of the TLP; based on whether the TLP is communicated between the hosts and endpoints in different hierarchies of the plurality of hierarchies, determine whether to edit the TLP using one or more rewrite rules; and forward the TLP to an appropriate destination link.
