Cisco Cisco IOS Software Release 12.4(4)T

CSCsu36827

Symptoms: CUE clock does not synch up with the CME using NTP. 

Conditions: When UC500 is configured as NTP master. 

Workaround: Use external NTP server other than UC500. 

CSCsu45608

Symptoms: A zone-based firewall does not allow returned TCP traffic from a VPN tunnel.

Conditions: This symptom is observed when the firewall is configured to inspect TCP traffic to and 
from the VPN tunnel.

Workaround: There is no workaround.

CSCsu47037

Symptoms: A router crashes when an attempt is made to forward a packet out of an Auto-Template 
interface. This occurs because the interface’s MTU is set to 0. The show interface Auto-Template 
X command displays an MTU of 0.

Conditions: This symptom is observed when an attempt is made to forward a packet out of an 
Auto-Template interface.

Workaround: Configure a protocol MTU directly on the Auto-Template interface (that is, ip mtu 
XXXX). 

CSCsu51095

Symptoms: If connected routes are optimized using PfR, there will be a routing loop. 

Conditions: This symptom can occur if for some reason pfr is learning connected routes or if the 
user has configured them.

Workaround: The workaround is to create an oer-map with a prefix-list that contains the prefixes 
with ip addr of the connected routes (next hops). Set the set observe mode in the oer-map.

CSCsu61741

Symptoms: The lsp ping command is missing. 

Conditions: This issue is specific to the Cisco 7301. 

Workaround: There is no workaround.
