Cisco Support in Ukraine After End of Life

If It Traverses the Network, It Is Not Out of Band

A management path that reaches a device through the network that device is part of shares its failures. The events that create the need for out-of-band access — a routing failure, a configuration change that locks everyone out, a device booting with no network — are precisely the events that remove a network-dependent path. It is management access, and it is not out of band.

Independence of Failure Is the Property, Not the Medium

A console server attached to device serial ports, reachable over a path that does not cross the production network, is what the term means. Historically that was a dedicated line and is now frequently cellular. The medium is incidental; what matters is that the path and the managed network cannot fail together.

A Serial Console Works When Nothing Else Does

It functions when routing is broken, when an access list has locked out every administrator, and when a device has come up in a state with no network configuration at all. Those are exactly the circumstances in which the alternative is sending a person to the building, which makes the console the highest-value access path in the estate and the least used.

The Cables Are What Go Missing

Console adapters and cables are specific to device families, cost very little, and are invariably not findable at the moment somebody needs one. ICD supplies them alongside console server hardware, switching and UCS components for platforms past Cisco end of support, tested and covered for one to three years, with enquiries for this destination answered case by case.
