This section describes possibly unexpected behavior by Release 12.2(4)YG. Only severity 1 through 3 
caveats are included.

When checking the firewall audit for TFTP, the TFTP data session responder log for the number of bytes 
transferred is not shown correctly. Note that the feature works—only logging is affected.

When PPPoE dial on demand is configured, a SOHO 76 or SOHO 77 router unexpectedly reloads while 
trying to remove the dialer interface from dialer pool 1.

The OAMF5 Segment CC feature does not work on SOHO 76 or SOHO 77 routers. Although the 
command seems to be accepted, it does not appear in the running configuration. No segment CC cells 
are sent and no debug output is displayed. When enabling segment CC on a peer, the router unexpectedly 
reloads after receiving the CC cell.

When you configure OAM loopback on a Cisco router using the command oam-pvc manage, the PVC 
goes down after receiving AIS/RDI cells from the peer, but does not come up again after receiving OAM 
loopback cells. To work around this problem and make the PVC come up, for the ATM interface enter 
the command shutdown followed by the command no shutdown.
