fwiw, one of the co-chairs of the IRTF's Crypto Forum Research Group is
David McGrew, who works for Cisco:

 https://www.irtf.org/cfrg

I'm cc'ing David here, because i figure he would be interested in
hearing this concern about cryptographic choices in Cisco's products,
though i don't know whether his position within Cisco gives him the
ability to address the situation.  At the very least, i figure he'd want
to be aware of it.
