Teaming Cisco switch ports for redundancy

Is there a way to team 2 cisco switch ports so that if a cable is accidentally pulled, a user multi-million transaction wont be affected at his desk. How can we make sure that if a port goes down, a user's pc is still up?

Are you talking about a server, or user workstation here (and how are your wires getting pulled?).

NIC teaming allows multiple ports from (typically) a server to go into different ports on a switch, or in some instances, into diverse switches. Because they are teamed, they are configured as a unit, and will end up with the same IP address. Because of this, one will probably end up as a hot-standby to the other – although I don’t know if switchover in the case of a cable being yanked, is “instantaneous”.

——————————

“teaming” is more of a server-level term. Cisco refers to this as Link-aggregation, or Ether-channels. These are typically trunk links between network infrastructure devices, like switch to switch…

One thing you could do, and that I’ve seen done multiple times, is either have 2 Wired NICs running to the switch, or have one wired and one wireless connection. Both of those still have about a 5-10 sec failover, but that typically doesn’t drop applications or interrupt data transfers (which expect a bit of delay)
