Cisco Cisco IOS Software Release 12.2(2)XJ

The Operations Administration Maintenance (OAM) F5 Continuity Check (CC) Segment Support 
feature functions with Alcatel Digital Subscriber Line Access Multiplexers (DSLAMs), which 
transparently switch OAM F5 CC Segment cells. Cisco DSLAMs terminate (do not forward) OAM F5 
CC Segment cells, and therefore do not provide OAM F5 CC segment support.

On Cisco 1700 routers, specify the Peak Cell Rate (PCR) and Sustainable Cell Rate (SCR) as multiples 
of 32 Kbps. Other rates are treated as the next lower value of a multiple of 32. For example, an entered 
PCR value of 150 is considered 128.

Booting a Cisco 1700 series router with the commands boot flash or boot system flash results in 
unpredictable behavior. To work around this problem, be sure to enter a colon (:) following both 
commands (for example, boot flash: or boot system flash:.)

Caveats describe unexpected behavior or defects 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.

All caveats in Release 12.2 T are also in Release 12.2(2)XJ. For information on caveats in Cisco IOS 
Release 12.2 T, refer to the 

document. For information on caveats 

in Cisco IOS Release 12.2, refer to the 

document. These documents 

list severity 1 and 2 caveats, and are located on CCO and the Documentation CD-ROM. 

If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for 
any release. You can reach Bug Navigator II on CCO at Software Center: Cisco IOS Software:
