[c-nsp] Protocol Errors

[Church, Charles]

It's hard to tell if that an input or an output error.  If it's input,
is it possible you're receiving protocols you don't have configured -
IPX, Appletalk, IPv6, some other ethercode?  Something to do with the
PPPOE maybe?

Thanks..

When I "spot check" a bunch of other 7206's we never ever see "Unknown
Protocol" errors.... I guess because we've never seen them before had me
wondering what's going on...;)

This isn't really that large a number when you look at the total number
of
packets compared to the number of drops.  You're only dropping 0.000043%
of
the traffic.

Anyone clue me in as to why we would be getting so many drops,
especially
"unknown protocol"?

dis1-rtr-pt#sh interfaces GigabitEthernet 0/3

This is on a 7206VXR router - the 0/3 interface has several
subinterfaces
including a PPPOE interface as well.....
