If the BRIDGE is a DATA LINK LAYER bridge, then YES. (People sometimes
take liberties with the word BRIDGE, these days...)

Correct. The router is moving packets at the NETWORK layer, not the
DATA LINK layer. Thus the Ethernet AM will not work. YOu would need to
use a management protocol that the ROUTER was able to ROUTE.

Is there any solution to manage PC over router ?
(Specifically, with current POLYCENTER Network Manager product.)

Yes, all of the packets generated by the Ethernet AM should travel
across the Ethernet-to-FDDI bridges to the PC (assuming you're not
explicitly filtering them).
Note that, for IEEE802 packets, the following also works (though
you must register the Station with an Alternate Address with
bits in the opposite direction):
IBM 8209

--------------------- ===========
Ethernet Token Ring
Remember that Ethernet AM packets come in several flavors:
- Enet V2 generic [Loop/Loop-w-Assist],
- DEC MOPv3 [REQID, Counters] - using Ethernet v2 packets
- IEEE 802.2 [XID, TEST],
- DEC MOPv4 [REQID, Counters (extended)] - using 802 packets.

Without a Bridge or BRouter (something to pass the Ethernet packets)
the Ethernet AM isn't much help.
For a DECmcc "solution to manage PC over router", it depends on what
the agent on the remote PC supports:
1. PNM's DECnet IV AM is a possibility
2. PNM's TCP/IP SNMP AM is a possibility
Hope this helps.

| If Pathworks is used, you may bring up Pathworks under DECnet or
TCP/IP. If under DECnet, load NML on the PC, then register as NODE4
entity. You may then unload NML. Configure the DECnet router to sink
events to the MCC node (Ask or send mail if you need instructions).
The router will watch for events on the end-node PC and you may target
the PC on the map. The router must be a DECnet IV router.
If you wish to manage via SNMP AM, configure Pathworks using TCP/IP as
transport. Register PC as SNMP entity. You can Ping it, but not much
more unless it has an SNMP agent running.
PC System Census (with agent) is now in field test. Their
implementation will likely provide you with everything you need to
manage PCs. Check it out.
