Known Restrictions and Limitations 
Release 5.1.0.1 
 
Description  User Impact 
SNMP walk is not successful while doing walk on root port  Low 
SNMP walk on root port may result in a 
timeout if executed without specifying any 
timeout value.  
 
Workaround: 
Execute walk with a recommended timeout 
value of 2 sec 
The IPMC L2_BITMAP is only updated to reflect ports that should 'not' be 
flooded when a multicast stream is 'first' seen on a VLAN. 
 
There will be some flooding of multicast 
traffic 
 
Workaround:  Issue  no ip multicast followed 
by ip multicast 
"ip http secure-server" may not be cleared after performing the clear config 
operation if there is user intervention before prompt returns 
 
Clear config operation clears all system 
components operational and configuration 
information and then builds the default 
configuration. This operation takes time to 
complete and the prompt may not be returned 
immediately. Prompt is returned after the 
completion of the operation. Please wait for 
the prompt, pressing "enter"/CR is not 
needed in this case. 
 
Workaround: Issue clear config one more 
time if “ip http secure-server” configuration 
is not cleared 
Reboot needed when critical message “Failed to add local route for network 
X/X on interface X”  appears on the console 
High 
Route is not added and hence critical 
situation. Need a reboot to recover.

System – 5.0.1.3 
Stacking 
Under certain conditions 5 or more ports 
identified as stacking ports can cause 
transmission errors even if the stacking 
links are not up. 
This problem happens infrequently and setting those ports back to Ethernet mode 
has corrected the problem.
