Table 63. Fixed Wake-up Configuration Bits
The controller only filters the shaded fields in the frame format above. Only the two low bytes of
the IP address are compared. The controller does not check for VLAN type (any frame with type
different than 0806 is treated as a VLAN frame if VLAN ARP is enabled).
Configuration Bits for Fixed Wake-up filters
The following configuration bits were added to the 82558 B-step to support fixed wake-up
filtering:

This bit enables a wake-up event upon reception of ARP frames with a dynamic
presence of a VLAN header. This bit takes effect only if the ARP enable bit is
also set.
This bit enables assertion of the PME# signal upon a link status change event.
The PME# signal is further gated by the PME enable bit in the PMCSR.
This bit enables assertion of the PME# signal upon reception of ARP frames.
The PME# signal is further gated by the PME enable bit in the PMCSR.
