Cisco Cisco IOS Software Release 12.4(4)T

Symptoms: Router may install duplicate routes or incorrect route netmask into route table. It could 
happen on any routing protocol. The problem is introduced by CSCsj50773. See the Integrated-in 
field of CSCsj50773 for affected images.

Conditions: The problem is triggered by SNMP polling of ipRouteTable MIB. The clear ip route * 
command can restore the route table until next polling of ipRouteTable MIB.

Workaround: Do not poll ipRouteTable MIB. Instead poll newer replacement MIB, ipForward MIB. 
The ipRouteTable MIB was replaced by ipForward MIB in RFC 1354. 

CSCsm46203

Symptoms: High CPU usage occurs when setting up IPSec tunnels using signature authentication.

Conditions: Occurs on a Cisco 7200 with a VSA accelerator used to perform a large number of 
signature (RSA) operations.

Workaround: Switch to a pre-shared key method for IKE authentication.

Further Problem Description: Occurs because the VSA card is not used to accelerate RSA 
operations. Instead those operations are performed in software, which increases CPU usage. 

CSCsm46227

Symptoms: Cisco 3845 may crash when there is an incoming trunk call.

Conditions: Occurs if the shared trunk DN is monitored by a FXO port and it is call-forwarded to 
another trunk DN with “call-forward all”.

Workaround: There is no workaround. 

CSCsm48415

Symptoms: Cisco Customer Voice Portal (CVP) does not release the port if a user hangs up during 
database look up.

Conditions: Occurs with the following software configurations: - CVP 3.0 and Cisco IOS Release 
12.4.(3g) - CVP 4.1 and Cisco IOS Release 12.4(15)T

Workaround: There is no workaround. 

CSCsm48489

Symptoms: PA links do not come up, and the following errors are seen: : 

%T3E3_EC-3-PA_SW_ERR: T3E3_EC on 1: Invalid Link Record anyphy number Software error 

was encountered. : %T3E3_EC-3-PA_CMD_RETURN_ERR: T3E3_EC command T3E3_EC_SCMD_VC_MTU 

return error 2,

Conditions: Occurs on Cisco 7206VXR with NPE-G2, SA-VAM2+, and PA-T3/E3-EC and using the 
c7200p-advsecurityk9-mz.124-15.T3.bin image.

Workaround: Choose one of the following: - Boot the router without any configuration on 
PA-T3/E3-EC. Configure card type once the router boots up completely. -Remove the VAM2+ 
module. -Use a PA-2T3 as an alternate to the PA-T3/E3-EC. 

CSCsm50498

Symptoms: During normal operation of Gateway Load Balancing Protocol (GLBP), when state 
changes from active to listen, the router stops forwarding traffic destined to the virtual MAC. Router 
still responds to the interface MAC.

Conditions: Occurs on Cisco 1700 routers running Cisco IOS Release 12.4.

Workaround: There is no workaround. 

CSCsm57910

Symptoms: All counters stay at zero when the sh policy-map session command is entered and when 
the forwarding sessions on the LAC router are being terminated on a remote router
