New Software Features in Cisco IOS Release 12.2(50)SQ
This section describes the new and modified software features supported in Cisco IOS Release
12.2(50)SQ.
Supervisor Stateful Switchover
In the Supervisor Stateful Switchover (SSO) mode, the standby Supervisor card is fully initialized and
configured. This allows SSO to reduce the switchover time if the active Supervisor card fails, or if a
manual switchover is performed. Both the startup and running configurations are continually
synchronized from the active to the standby Supervisor cards, and the line cards are not reset during a
Supervisor switchover. The interfaces remain active during the switchover, hence the neighboring
routers do not detect a physical link flap (the link does not go down and back up).
The SSO feature supports both the DEPI Manual and the DEPI Protocol modes. It is unavailable for
Video in Cisco IOS Release12.2(50)SQ.

M-CMTS DEPI Control Plane
The Downstream External PHY Interface (DEPI) control plane is based upon Layer Two Tunneling
Protocol-Version 3 (L2TPv3) signaling. The DEPI is the communication protocol over an IP tunnel
between the Modular Cable Modem Termination Systems (M-CMTS) core and the Edge Quadrature
Amplitude Modulation (EQAM). It is an IP tunnel between the MAC (M-CMTS Core) and PHY
(EQAM) in an M-CMTS system, which contains both a data path for Data-Over-Cable Service Interface
Specifications (DOCSIS) frames and a control path for setting up, maintaining, and tearing down data
sessions.
The DEPI Latency Measurement (DLM) packet is a special type of data packet used for measuring the
network latency between the M-CMTS core and the EQAM.
