Duplicated SPE Standby Packet Interface
Reset of a packet interface on the standby SPE does not disrupt service and
results in a reset of all packet interfaces on the standby SPE. The following
conditions are necessary:
■ Handshake communication is up.
■ The SPE carriers are not locked with the SPE-Select switches.
The following sequence occurs:
1. Memory shadowing is turned off.
2. All standby packet interfaces are reset.
3. If the reset succeeds, shadowing is turned on, memory refresh initiated,
and the packet is put into the standby state.
4. If the reset fails, the circuit pack is put into the out-of-service state,
lowering the standby SPE’s state-of-health.
Duplicated SPE Active Packet Interface
Standby SPE available
When a packet interface on the active SPE of a duplicated system is specified, a
spontaneous SPE interchange is first performed by the system, assuming that:
■ The SPE carriers are not locked with the SPE-Select switches.
■ Handshake communication is up.
■ The state of health of the standby SPE is not lower than that of the active.
If these conditions are met, the interchange places the active SPE into the
standby state, and then all standby packet interfaces are reset as in the above
case. Links are not disrupted, but due to the interchange transient calls are
dropped and the terminal is logged off.
Standby SPE Not Available
If any of the three conditions listed above are not met, an SPE interchange is
prevented and the active packet interface is reset, resulting in disruption of all
links associated with the circuit pack (see the Caution above). When the
interchange is prevented by lower state of health of the standby, the standby
packet interfaces are also reset according to the sequence listed above.
