Cisco Cisco IOS Software Releases 12.2 MC

CSCsa81379

Description: NetFlow Feature Acceleration CLI.

NetFlow Feature Acceleration has been deprecated and removed from Cisco IOS. The global 
command ip flow-cache feature-accelerate will no longer be recognized in any IOS configuration. 

If your router configuration does not currently contain the command ip flow-cache 
feature-accelerate, this change does not affect you.

This removal does not require an upgrade of your existing installation.

The removal of NetFlow Feature Acceleration does not affect any other aspects of Netflow 
operation, for example Access-list processing. The features are separate and distinct.

Cisco Express Forwarding (CEF) supercedes the deprecated NetFlow Feature Acceleration.

Additionally, the following MIB objects and OIDs have been deprecated and removed from the 
netflow mib (CISCO-NETFLOW-MIB):

The following sections list and describe the open and resolved caveats for the Cisco MGX-RPM-1FE-CP 
with Cisco IOS Release 12.2(15)MC2a. Only severity 1 through 3 caveats are included.

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most 
serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these 
three severity levels.

Caveats in Cisco IOS Releases 12.2 and 12.2 T are also in Cisco IOS Release 12.2(15)MC2a. For 
information on caveats in Cisco IOS Release 12.2, see Caveats for Cisco IOS Release 12.2. For 
information on caveats in Cisco IOS Release 12.2 T, see Caveats for Cisco IOS Release 12.2 T. These 
two documents list severity 1 and 2 caveats and are located on CCO and the Documentation DVD. 

If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of any severity for 
any release. To reach Bug Navigator II, Login to Cisco.com and click Software Center: Cisco IOS
