Hi,
I'm not sure I explained myself correctly......(And I don't
understand what your trying to accomplish above)
The setup looks like this :
TRANSIT1 TRANSIT2
| |
|-E0/0 |-E1/0
| |
-------------------------------------
3640
-------------------------------------
| |
|-E0/1 |-E1/1
|--------BVI1-------------|
| |
|-FA0/24 |-FA0/24
---------- ------------
2924-1 2924-2
--------- ------------
|-FA0/15
|
|-Netgear Ethernet Over Power Extender
So its complaining that FA0/15 on 2924-1 is mismatched
to E0/0 on the 3640. Well, DUH, no fooling. I would think
the only things it cares about are 3640~E0/1&2924-1~FA0/24
and 3640~E1/1&2924-2~FA0/24 since those are the only 2 places
that the Ciscos directly connect.
For those that wanted more info, E0/0 is connected
to a Proxim Wireless Broadband antenna at 10/half, E1/0
connected to a Hughes Satellite Modem at 10/half, E0/1 and
E1/1 are bridged (BVI1) and connected to the 2924's at
10/half. The Netgear is connected to 2924-1 at 100/full.
The 2924's and 3640 are only Cisco equipment at the
site.
