Subject: Re: Dynamips - duplex/speed mismatches, cannot correct ?
Hi John,
The duplex can be set for both ethernet and fast ethernet interface on
the router that attached to that switch.
The fast ethernet interface has speed settings enabled compared with the
ethernet counterparts.
I have set the duplex to match between the attached router and the
switch.
However, the duplex could be able to be set only from the router side to
get rid of that annoying CDP messages of duplex mismatch.
Hope it helps,
DC
