View code. Default timestamp setting—The timestamp prompt that precedes console output is enabled by default. To disable the timestamp prompt, use the no service timestamp command. Country-specific laws, regulations, and licenses—In certain countries, use of these products may be prohibited and subject to laws, regulations, or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the countries in which they intend to use the products.
Field replacable unit FRU removal—For all card removal and replacement including fabric cards, line cards, fan controller, and RP follow the instructions provided by Cisco to avoid impact to traffic.
Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration for your purpose. When upgrading a system from a release prior to 3. If this bundle member is removed from the bundle, the bundle gets a new MAC address, which results in traffic loss due to ARP resolution. Deactivation of os-mbi dependent Nonreload SMU fails—Backing out the non reload os-mbi SMU fails because deactivation runs out of memory activation did not release some memory, which stayed at 38 MB.
One way of achieving this is by configuring a lower session hold time between neighbors such that session time out always occurs before hello adjacency can time out. Cisco recommends setting LDP session hold time using the following formula:.
Severity-1 caveats are the most critical caveats; severity-2 caveats are less critical. Cisco IOS XR Software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes.
Software packages can be upgraded or downgraded on all supported card types, or on a single card node. Software packages are installed from package installation envelope PIE files that contain one or more software components. Before starting the software upgrade, use the show install health command in the admin mode.
This command validates if the statuses of all relevant parameters of the system are ready for the software upgrade without interrupting the system. However, there is no functionality impact seen during the normal operation of the router. Production SMUs are intended for use in a live network environment and are formally supported by the Cisco TAC and the relevant development teams.

Cisco Bug Search Tool BST is a web-based tool that acts as a gateway to the Cisco bug tracking system that maintains a comprehensive list of defects and vulnerabilities in Cisco products and software.
BST provides you with detailed defect information about your products and software. Skip to content Skip to search Skip to footer. Available Languages. Download Options. Updated: July 31, Use faceted search to locate content that is most relevant to you.
Create customized PDFs for ready reference. Benefit from context-based recommendations. Do provide feedback about your experience with the Content Hub. There are no new software features introduced in this release. Hypervisors A hypervisor enables multiple operating systems to share a single hardware host machine. Table 3. PCI passthrough only.
SRIOV is not support. This feature improves the serviceability of the XIPC queues. To perform this, the TCP monitors and identifies the sessions that are receiving more data. TCP revisits the statistics at regular intervals, and based on the data, it decides whether the sessions need to be policed or added to default policer rate.
Therefore, other sessions are given a fair chance to use the XIPC queue, and high-data sessions are throttled down at hardware. If the calculated queue-limit in a QoS class applied to an interface is less than 1kB, the queue-limit is automatically adjusted in hardware to 1kB.
With the Cisco digital CFP2 pluggable optical module, the Digital Signal Processor DSP chip resides directly on the pluggable module, providing a more complete and compact solution that can be used across all platforms with the CFP2 interfaces. To check the firmware code running on the Cisco ASR Series Router , run the show fpd package command in admin mode. To check the firmware code running on the Cisco ASR Series Router, run the show fpd package command in admin mode:.
Repetitive Smart Licensing evaluation expired warning messages are displayed on the console every hour, but no functionality impact is seen on the device. To stop these repetitive messages, you should register the device again with new registration token. These line cards comply with G. Country-specific laws, regulations, and licenses—In certain countries, use of these products may be prohibited and subject to laws, regulations, or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the countries in which they intend to use the products.
Card fan controller, and RSP removal —For all card removal and replacement including fabric cards, line cards, fan controller, and RSP follow the instructions provided by Cisco to avoid impact to traffic. Exceeding Cisco testing—If you intend to test beyond the combined maximum configuration tested and published by Cisco, contact your Cisco Technical Support representative to discuss how to engineer a large-scale configuration for your purpose.
Installing a Line Card—For a fully populated port high density Line Card with cable optics, maintenance time required for card replacement is higher. Serial Interfaces Out of Order in show ipv4 interface brief or show ipv6 interface brief command—The show ip interface brief command might display interfaces out of order if different types of serialization are used on the SPA cards.
The serial interfaces are displayed in the show ip interface brief command output in the order shown in the example below:. This may be different from the usual order as the interfaces appear out of order for the user who is accustomed to IOS.
