New Hardware Features in Cisco IOS Release 12.0(33)S2
There are no new hardware features in Cisco IOS Release 12.0(33)S2.
New Software Features in Cisco IOS 12.0(33)S2
This section describes new and changed features in Cisco IOS Release 12.0(33)S2. Some features may be new to Cisco IOS Release 12.0S but were released in earlier Cisco IOS software releases. Some features may have been released in earlier Cisco IOS software releases and have been changed in Cisco IOS Release 12.0(33)S2. To determine if a feature is new or changed, see the feature history table at the beginning of the feature module for that feature.
Flow-control CLI
Flow control functionality is particularly useful when a remote end does not support flow control and a need arises to disable flow control on a Gigabit Ethernet (GE) or Fast Ethernet (FE) interface on a Cisco 12000 series router. By default, flow control is enabled on a GE or FE interface. Use the show interface flowcontrol command to view the flow control configuration on interfaces. To enable flow control, use the flowcontrol bidirectional command; to disable flow control, use the no flowcontrol bidirectional command. The flow control configuration must be same on both ends of the link (both enabled or both disabled).
Prerequisites to Execute Flow Control CLIs
1) Commands supported on Cisco IOS Release 12.0(33)S2.
2) Supported on Cisco 12000 series routers.
3) Supported only on GE or FE interfaces of an Engine 5 SIP-401/501/600/601 line card.
4) Disable auto-negotiation using the no negotiation auto command before executing the [no] flowcontrol bidirectional command.
Caveats of Flow Control Functionality
1) Not supported on a GE SPA interface with a Copper SFP inserted in it.
2) Not supported on a 1-Port 10-Gigabit Ethernet SPA.
3) Not supported on the SPA-2X1GE-V2.
For more information, see the "SIP and SPA Commands" chapter of the Cisco 12000 Series Router SIP and SPA Software Configuration Guide, 12.0(33)S:
IPHC Over Frame Relay for Interface Support
IP header compression is a mechanism that compresses the IP header in a packet before the packet is transmitted. Header compression reduces network overhead and speeds up the transmission of either Real-Time Transport Protocol (RTP) or Transmission Control Protocol (TCP) packets.
The IPHC Over Frame Relay for Interface Support feature enables efficient transmission of real-time traffic such as voice and video by compressing and decompressing the packet header. IPHC over Frame Relay is supported on Cisco 12000 Series Engine 5 based SIP-401/501/601 line cards on Frame Relay interfaces. For Frame Relay, the Cisco encapsulation type is the only encapsulation type on which this feature is supported. This feature is already supported on PPP/MLPPP interfaces. This feature has been designed for slow links so that optimum usage of bandwidth can be obtained and so that the quality of delay-sensitive traffic such as voice and video is not affected. IPHC works by first sending a full-header, and as the difference in packet remains constant, it maintains a copy of the difference between the previous packet and the current packets. This data is referred to as the session context ID, which it uses to completely reconstruct the packet header by adding the difference.
For further information on this feature, see the following:

New Hardware Features in Cisco IOS Release 12.0(33)S1
This section describes new and changed features in Cisco IOS Release 12.0(33)S1. Some features may be new to Cisco IOS Release 12.0S but were released in earlier Cisco IOS software releases. Some features may have been released in earlier Cisco IOS software releases and have been changed in Cisco IOS Release 12.0(33)S1. To determine if a feature is new or changed, see the feature history table at the beginning of the feature module for that feature.
