I think the problem you'll have is support for 802.3ad on the Cisco (and
maybe the Linksys). As far as I can see, the 2924 (presumably 2924XL)
doesn't support link aggregation. Also, I'm not sure that adding extra
interfaces gives you much higher availability - usually a seperate box is
used for that with something like HSRP, VRRP or CARP so that both boxes
pretend to be a single machine.
