Release Notes for Cisco IOS Release 12.0 S

78-7130-11 Rev. B0

New and Changed Information

Cisco 7200-I/O-GE+E and Cisco 7200-I/O-2FE/E Input/Output Controllers

Platforms: Cisco 7200 series

The Cisco 7200-I/O-GE+E is an Input/Output controller that provides one Gigabit Ethernet and one

Ethernet port. It is equipped with a Gigabit Interface Converter (GBIC) receptacle for 1000 Mbps

operation and an RJ-45 receptacle for 10 Mbps operation.

The Cisco 7200-I/O-2FE/E is an Input/Output controller that provides two autosensing Ethernet or

Fast Ethernet ports and two RJ-45 receptacles for 10/100 Mbps operation.

I/O controllers support the following features:

• Dual EIA/TIA-232 channels for local console and auxiliary ports

• NVRAM for storing the system configuration and environmental monitoring logs

• Two PC card slots that hold Flash disks or Flash memory cards for storing the default Cisco IOS

software image

• Flash memory for storing the boot helper image

• Two environmental sensors for monitoring the cooling air as it enters and leaves the chassis

Extended ACLs on PSA

Platforms: Cisco 12000 series

The Extended ACLs on PSA feature provides 448-Lines Access Control Lists (ACLs) support on the

Performance OC-48 line card by implementing the functionality in the Packet Switching ASIC (PSA).

FRF2.1 Annex 1

Platforms: Cisco 12000 series

FRF2.1 Annex 1 for Event Driven Procedures provides a signalling protocol for permanent virtual

circuit (PVC) monitoring at the Network-to-Network Interface (NNI) for a frame relay switching

network. FRF2.1 Annex 1 generates notification when an event occurs to change status and when an

event occurs, it generates immediate notification.

It allows for faster notification of PVC status, such as addition, deletion, or availability, in frame relay

switching networks with multiple switching nodes. The faster notification results in better network

management as well as increased PVC scalability per interface since LMI procedures are not needed at

each NNI node for each PVC in the network.

FRF2.1 Annex 1 adds event driven procedures to the enterprise frame relay network. It enables fast

convergence and provides quick responses to any changes within a frame relay network. See the

following document for further information:
