M1. 0 but may be open in previous Cisco IOS releases. This may not be service affecting. Conditions: This is seen during a stress test of 1. Workaround: There is no workaround.
The router is configured for VPDN/L2. TP. There is a mixture of PPPo. VPDN and . Qo. S service policy with queuing actions (bandwidth guarantee or shaper) is applied to virtual access interfaces for both types of users. Here is a way to find out if there is normal PPP users or MLP users: Router#sh user . Allow only PPPo. VPDN (i. Disable Qo. S for .

Exploitation of this vulnerability could cause an interruption of services. Only devices that are configured for SIP inspection are affected by this vulnerability. Cisco has released free software updates that address this vulnerability. There are no workarounds for devices that must run SIP inspection.

Cisco. Security. Advisory/cisco- sa- 2. Note: The March 2. Cisco IOS Software Security Advisory bundled publication includes seven Cisco Security Advisories. All advisories address vulnerabilities in Cisco IOS Software. Each Cisco IOS Software Security Advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all Cisco IOS Software vulnerabilities in the March 2.
Individual publication links are in . The caveats in this section are resolved in Cisco IOS Release 1. M9 but may be open in previous Cisco IOS releases. The user will not notice if a PRC error occurred. Conditions: This symptom is observed when the PRC error result status is not sent back from Standby to Active properly.
Workaround: After the system reaches the SSO state, issue the following exec command via the Active console to check if PRC error occurred. The ip address negotiated command would then trigger IPCP re- negotiation and the session would come up on active.
On standby, the session remains down and the new IP address is not synced. Workaround: There is no workaround. Restarting.. Conditions: The symptom is observed on a Cisco 8. Cisco IOS Release 1. T3. Workaround: There is no workaround. Earlier versions are not affected.
This occurs with the same prefixes with different mask lengths, e. It is seen with the following process: 1. Assume the prefix, 1.
VPNv. 4 to VRF. It has been allocated a label of 1. The allocated label changes from 1. BGP attribute change. However, before the BGP import happens, a more specific prefix (e.
BGP radix tree, but it is denied for importing due to, say, RT policy. Workaround: Remove RT or import map and add it back.
Note, however, that if the above conditions occur again, the issue could reappear. The F/S pool is used for fragmentation, so this will only occur when there is a large amount of fragmentation occurring. It has only been seen when there is a .
Reduce hold queue sizes such that the total size of the queues for all active interfaces in the system does not exceed 5. The rx ring is stuck and it may be observed that all packets coming into the interface are counted as . It may be seen at random times and has thus far been observed to happen after an interface bounce. The interface will still show . However, the issue is not browser- specific and other browsers might trigger the issue too.
PSIRT Evaluation: The Cisco PSIRT has assigned this bug the following CVSS version 2 score. The Base and Temporal CVSS scores as of the time of evaluation are 6. Calculator. do? dispatch=1& version=2& vector=AV: N/AC: L/Au: S/C: N/I: N/A: C/E: F/RL: U/RC: CCVE ID CVE- 2.

This crash can be seen on the following platforms: Cisco 8. W, 1. 80. 0W, UC5. W, and 2. 80. 0 and 3. HWIC- AP. The crash is only seen when an i. Phone 4. S is connected to the router. The crash has most commonly been triggered by running a video call application on the phone, but there may be other triggers.
Other than the wireless configuration and other generic configurations needed to provide connectivity to the router, no other specific configuration is needed to see the crash. Workaround: No workaround on the router.
However, this issue is not seen with an i. Phone 4s running i. OS 5. 1. The issue is only seen on i.
OS 5. 0. PSIRT Evaluation: The Cisco PSIRT has assigned this bug the following CVSS version 2 score. The Base and Temporal CVSS scores as of the time of evaluation are 6. Calculator. do? It appears to reload just after registration: %GDOI- 5- GM. Workaround: There is no workaround.
Workarounds that mitigate this vulnerability are available. This advisory is available at the following link: http: //tools. Cisco. Security. Advisory/cisco- sa- 2. Affected devices must be configured to process SIP messages and for pass- through of Session Description Protocol (SDP) for this vulnerability to be exploitable. Cisco has released free software updates that address this vulnerability. There are no workarounds for devices that must run SIP; however, mitigations are available to limit exposure to the vulnerability. This advisory is available at the following link: http: //tools.
Cisco. Security. Advisory/cisco- sa- 2. Incoming traffic is OK but no traffic is going out over the tunnel. Inspection of the IVRF routing table shows that there is a route to the remote destination with the correct next hop, but the route does not point to the egress interface (the interface with the crypto map in the FVRF). For example, the IVRF routing table should show: S 1. For example: ip route vrf IVRF 1.
Gigabit. Ethernet. Gigabit. Ethernet. FVRF with the crypto map, and 1.
FVRF through which the VPN peer is reachable. In the logs you see: esw. However, it refers to about 5. This symptom may not be restricted to the Meetingplace application server alone.
Conditions: The call needs to engage/disengage/engage the IOS XCODER (HW transcoder) in quick succession due to a mismatched codec. Workaround: There is no workaround. Further Problem Description: Running Cisco IOS debug command debug voip xcodemsp error and debug voip xcodemsp error will print an error message like the following: sym. System is experiencing excessive ambient temperatures and/or airflow blockage. Please resolve system cooling to prevent system damage. Conditions: This has been seen on a Cisco 2. Cisco IOS Release 1.
M, when air intake temperature goes below 0. C. Workaround: There is no workaround. Unfortunately, it does not check if this RTP port is in use for a different call, and therefore crosstalk can occur. Feb 2. 7 1. 7: 5. BF7. 61. 75. BB2.
SIP/Media/sip. SPIAdd. Stream. Reusing old src. Currently the following Alert- Info is sent to SIP phones for an external call: The alert- parameters should be bracketed by < and >. Conditions: The symptom is observed with SIP phones in SRST mode. Workaround: There is no workaround.
Affected platforms include (this is not a complete/exhaustive list) –c. E, c. 39. 45. E –c. VAM2+/VSA, –possibly VPNSPA on c. K –8. 19. H –ISR G2 routers with ISM IPSec VPN accelerator. Workaround: There is no workaround. In addition, when a ping sweep is done, aborts and input errors are seen more frequently.

IPS: –Access the router via the console. If a comma is used, there should be a pause after connecting before sending the digits. The default value of the digital modem is one second per comma; two commas would be two seconds, three commas = three seconds and so on. With any number of commas in the string, debugs show the digits are sent at random intervals, sometimes before the call was answered and as much as up to 3.
With no comma in the dial string, the digits are sent immediately after being generated without waiting for a connection, i. Dialing directly to a number with no extension or extra digits works as expected. Workaround: There is no workaround. The issue is seen only when one of the negotiating routers is a non- Cisco device where the key size attribute is not sent in ISAKMP proposal. Workaround: Remove ISAKMP policy with AES encryption. As a result, there is a DSP resource leak. Conditions: The problem can happen in the following situation: –CUBE receives 1.
Apple issues i. OS 1. Apple today released an eighth beta of i.
OS 1. 0 (build number “1. A5. 34. 6a”) to members of the Apple Developer Program and the seventh beta of i. OS 1. 0 to public beta testers who are signed on the Apple Beta Software Program. It’s worth repeating that i. OS 1. 0 beta 8 for developers and i. OS 1. 0 beta 7 for public beta testers contain the same features. The devices on a prior beta can be updated in Settings .
