Due to an error in the code, only the memory structures associated with data from the last DHCP server are properly released after a lookup. Data from other servers in the list is retained indefinitely with each lookup. When a device has an empty ACL, it fails to deny all traffic. This problem occurs when an empty ACL is present in the policy. Avoid oversubscribing the member link.
Also, the user is not notified and the logs do not contain information on the failure s. Because of this, the TAC will not be able to help the user. The message below is a generic message and not specific to a crypto self-test failure. When a router has an empty ACL, it fails to deny all traffic.
In the event of some test failures, the user will not be notified. The logs will also contain no information on the failure s so TAC will not be able to help the user. The message below is a generic message and not specific to a crypto self test failure.
This message does not give enough information for the user to take the proper course of action. Loss of keepalive packets caused by a low priority flow being raised to high priority. When FRF. HP2 traffic is throttled even when under-subscribed. Modules need to absorb bursts without impact to priority handling, latency and throughput. Configure and unconfigure the platform shell configuration command to recover the license to proper working state.
The user will see the system shaping to too low a rate when a tunnel moves to a faster interface, and shaping to too high a rate when a tunnel moves to a slower interface. If it is not possible, then after a tunnel moves occurs, modify the shaping percent by plus or minus 1 percent, and then restore to original value, because this forces a recalculation of the shaping rate. Perform OIR and configure few channel-groups. Then swap original board back.
Perform shutdown , no shutdown , or power inline never , power inline auto in the GigE port where the PoE device is plugged in. This effectively causes a much-shorter re-registration window compared to the one obtained at the GM registration, even if the original TEK lifetime was configured with a long value. QoS pre-classify is configured under IPsec tunnel.
Using an 8-port CT1E1 controller, with the E1 card type and channel groups configured, followed by 2. OIR with a 1-port model configured with 31 channel groups , then 3. OIR back to the original 8-port CT1E1, which results in the first controller's channel groups failing to come up.
Remove the failed channel groups, and re-configure them for the controller. Failure message Embedded hash verification failed is returned during copy operations on non-image files. Current work around is to always configure ds0-group first, then configure channel-group or tdm-group. Any traffic going through the Cisco ISR's data plane is dropped.
Issue is seen only after power cycling the box multiple times. Power cycle the box again to recover from the issue. When the module is unresponsive to host control packets. The packet drops will be shown as IpFormatEr in the error counts. The MIB tables do not populate. The control plane communication to the service module fails silently.
Any command CLI that requires a response from the module may fail. The error may also occur when using other service modules under different conditions. Shut and no shut of interface, causes that particular serial interface to toggle, but all interfaces don't come up. The show ipv6 cef exact-route command does not show the correct egress interface for traffic. In a network with multiple parallel paths, the show ipv6 cef exact-route command does not show the correct egress interface for traffic streams.
This happens when using any of the following cef load sharing algorithms:. The system is reset after the port-channel load-balancing vlan-manual command is entered, while traffic is running.
When the port-channel load-balancing vlan-manual command is entered to create a port-channel, while traffic is running, the CPP reloads and the system is reset. Ensure there is no traffic running when you configure a port channel using the port-channel load-balancing vlan-manual command. The number of octets shown in the drop statistics, is 0 zero , as shown in the following example:.
Global Drop Stats Packets Octets. Firewall Nonsession 0. Although the number of dropped packets is shown correctly, the number of octets is shown as 0 zero. Cisco IOS software command output shows a negative file size for core files which are larger than 2GB kernel core dump. The output which appears showing the file size as negative is not the main issue.
The main issue is that a file greater than 2GB in size, cannot be copied via the management port or using tftp. If you need to copy a large file such as this, please contact Cisco TAC to help you copy the file using the platform shell.
The configuration guides are consolidated platform-independent configuration guides organized and presented by technology. However, there is only one set of command references because they are platform independent.
Information in the configuration guides often includes related content that is shared across software releases and platforms.
Additionally, you can use Cisco Feature Navigator to find information about feature, platform, and software image support.

Determining the Software Version You can use the following commands to verify your software version: For a consolidated package, use the show version command For individual sub-packages, use the show version installed command.
Upgrading Field-Programmable Hardware Devices The hardware-programmable firmware is upgraded when Cisco Series ISR contains an incompatible version of the hardware-programmable firmware. Feature Navigator You can use Cisco Feature Navigator to find information about feature, platform, and software image support.
Dial on Demand Dial on demand feature is not supported on Cisco series platform. Limitations and Restrictions in Release 3. To configure the feature, use the platform hardware throughput command, as shown in the following example: Example Router config platform hardware throughput level? Router config platform hardware throughput level Smart Licensing is the next generation licensing platform for all Cisco software products.
Domain-Based Whitelisting for Cloud Web Security—Domain-based whitelisting allows you to bypass some of the web traffic directly to web-server and helps you to skip the Cisco Web Security scanning. Cisco IOS software provides a wide array of voice features on gateway routers. Note : Multicast connection trunk is not included in this release. The command debug vpm sig to monitor the connection trunk signaling is not applicable in Cisco series platform as these signaling packets are no longer sent to IOSd in Cisco series ISR.
They are handled in data plane by DSP. SIP and H. For more information on SIP and H. This feature provides a cost-effective way to increase the bandwidth for particular applications by enabling multiple serial links to be aggregated into a single bundle of bandwidth. For more information, see the Frame Relay - Multilink chapter. You can configure the media for failover redundancy when the network goes down. When you receive a second call, you hear a call-waiting tone a tone with a ms duration.
Caller ID appears on phones that support caller ID. Call Transfers— Call transfers are when active calls are put on hold while a second call is established between two users. After you establish the second call and terminate the active call, the call on hold will hear a ringback.
The Call Transfer feature supports all three types of call transfers—blind, semi-attended, and attended. Music streams from an MOH server to the voice interfaces of on-net and off-net callers that have been placed on hold.
Cisco Communications Manager supports the capability to place callers on hold with music supplied from a streaming multicast MOH server. Media can be configured for failover redundancy when the network goes down. Before You Begin. Workaround: Apply the following view to exclude cEigrpInterfaceEntry from being polled: — snmp-server view cutdown iso included — snmp-server view cutdown 1.
