The Intel Pro/100 Server Adapters (dual port) support adapter teaming (port
bundling). For fault tolerance, a failed primary adapter will pass its MAC
and L3 address to the secondary adapter. Although this works with any hub or
switch, the teamed ports must be connected to same hub or switch.
For failover between switches, these NICs support dynamic 802.3ad, or Link
Aggregation Control Protocol (LACP). You will need 4000 or 6000 class
switches for dynamic 802.3ad support but I have not tested Cisco's dynamic
mode for compliance and issues. Most switches only support static mode.
These NICs also support Cisco FEC/GEC but teamed ports must be connected to
the same FEC/GEC switch.
My company uses these adapters for server NIC failover between 2948G
switches. The 2948G swithes do not support 802.3ad, so the failover breaks
many applications. It is my intention to test the failover later this year
using defferent switches.

Sorry for the off-topic post.
Has anyone ever heard of a product/device (doesn't necessarily have to
be Cisco) that will allow a PC to survive the failure of the hub or
switch that it is connected to? Any info would be helpful...
Now returning you to the normal lab topics.
Thanks,
