[cisco-bba] NPE-G2 with C7200-I/O-2FE/E

[Frank Bulk]

Bryan:

Points aren't a concern.  Can anyone point out any Cisco documentation that
points (no pun intended) out the limits?

We .1q tagged interfaces today on the existing FastEthernet ports, but
there's too much hairpinning for my liking, which is why I want to use
physical ports.  I diagrammed the traffic flows and using all 5 ports (3 GE
plus 2 FE) eliminates almost all the hairpinning.

We did the same thing over a year ago.  It is supported but not recommended.

Leaving the I/O boards in creates limits.  Programming would be through
the old I/O board.  Bandwidth points still apply with the old I/O board
in place.  All that for a couple of F/E ports . . .

Take out the old I/O board and _all_ the limits go away.

If you need additional ports, use .1q tagged interfaces via a Gig-E
switch . . . life goes on.
