Workaround: Do not use the quick option with the issu changeversion command. While configuring an IPv6 access-list, if you specify hardware statistics as the first statement in v6 access-list mode i. Similarly, your hardware statistics configuration will be missing from the output of the show running command.
Routed packets that are fragmented are not policed if the egress interface is on the VSS Standby switch. However, if the egress interface is on the VSS Active switch, these packets are policed. This applies to QoS policing only. QoS marking, shaping and sharing behave as expected. The boot up time depends on the configuration and on the number of line cards in the system.
Memory allocation failures can occur if more than 16K IPv6 multicast snooping entries are present. The show interface capabilities command output does not show the correct linecard model. They will appear only when a logging method is active e. Auto negotiation cannot be disabled on the Fa1 port.
These messages are cosmetic only, and no ssh services are available unless configured within IOS. When a logging discriminator is configured and applied to a device, memory leak is seen under heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In extreme cases, the device may crash. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved. The Cisco Bug Search Tool BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version.
The BST is designed to improve the effectiveness in network risk management and device troubleshooting. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
CRE Etherchannel ports on dual Supervisors go to suspended mode after switchover. Stack Member Switch fails wired dot1x; MasterSwitch passes dot1x using the same configs. Switches downstream of a Cat4k using 1g ports may see giants in the form of B frames.

The following permanent right-to-use licenses or base licenses are available: Enterprise Services—image supports all Cisco Catalyst X Series software features based on Cisco IOS Software, including enhanced routing. This section describes the system requirements:. The following table lists where you can find information about supported pluggable transceiver modules and the minimum Cisco IOS Software release required: Table 1. Major exceptions include: CFM D8.
The maximum MTE supported on Catalyst switches is , per direction. On connecting more than one AP the following error message will be seen: 3. Dec 5 Only one AP per port is allowed. Flow Sampling is not supported on Supervisor Engine 8-E. Workaround 1 : While a general purpose specification file entry may not be possible, a specification file entry might be created that returns the desired text by searching for text that is guaranteed to be in the output.
For example, the rules in this access list do not contain a common string and the order three permits, then a deny, then another permit , prevent the spec file entry from using permit as a search string, as in the following example: Extended MAC access list MACCOY permit Workaround: Define a policy-map with a different name and then reattach.
CSCti If the number of unique FNF monitors attached to target exceeds one per target , a switch responds slowly: Workarounds: — Decrease the number of monitors. CSCti ciscoFlashPartitionFileCount object returns an incorrect file count for bootflash:, usb0:, slot0:, slaveslot0:, slavebootflash:, and slaveusb Workaround: None. You cannot clear a large number of mroutes at one time when traffic is still running.
Workaround: Do not clear all mroutes at once. CSCtn Although you can configure subsecond PIM query intervals on Catalyst platforms, such an action represents a compromise between convergence reaction time and a number of other factors number of mroutes, base line of CPU utilization, CPU speed, processing overhead per 1 m-route, etc.
Workaround: Use the show version command. Workaround: Select an alternate destination or source port. Workaround: Configure both dead-criteria and deadtime.
CSCto While configuring an IPv6 access-list, if you specify hardware statistics as the first statement in v6 access-list mode i. You will not experience this behavior with IPv4 access lists. CSCuc The show interface capabilities command output does not show the correct linecard model.
Workaround: Observe the show module command output. To view the details of a caveat, click on the identifier.

All Community This category This board. Labels: Other Switching. Copy IOS image to bootflash: 2. Refer to the Cisco Technical Tips Conventions for more information on document conventions. Check whether your switch supports these requirements.
You can use the release notes to verify the requirements for the new software image. You can use any TFTP server that can be installed on any platform. Download the software image to the TFTP server root directory. You can download the images to the default root directory of the TFTP server or change the root directory path to the directory in which the software image resides.
Alternatively, deselect Enable Logging , and click Ok. By default, logging is enabled. Note: You can use remote Telnet access to upgrade the switch. However, you lose Telnet connectivity when the switch reloads during the software upgrade. You can re-establish the Telnet after the new image loads.
However, to troubleshoot in case of failure, you need to have local console access. Cisco recommends a switch upgrade through the console access. Sometimes, your upgrade procedure can fail due to these reasons:. You can recover the switch to normal mode with the same image that was present in the switch.
If you lose the switch configuration for any reason, you can restore the configuration from the TFTP server. If you have modified your configuration, make sure to issue the write memory command to copy the current configuration to startup configuration and perform the backup.
You can issue the copy bootflash: tftp: or copy slot0: tftp: commands to copy the current software images from bootflash or slot0 to the TFTP server. In this section, you are presented with the information to configure the features described in this document.
Note: Use the Command Lookup Tool registered customers only to obtain more information on the commands used in this section. You only have the option to copy the new software image from the TFTP server into the switch bootflash.
If you are not ready with this setup, see the Requirements section of this document. Step 2 : Configure the management IP address sc0.
