Why this is happening? Which fix can I use? The fsck didn't worked, so following the Mark's suggestion I started the switch in recovery mode and removed the OS image.
The switch didn't found the previous boot image and started with the factory one. The boot configuration was still pointing to the erased firmware file. Buy or Renew. Find A Community. Cisco Community. Join us in congratulating October's Spotlight Award Winners!

Use any of these workarounds to improve EtherChannel load balancing:. For example, with load balance configured as dst-ip with distinct incrementing destination IP addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is optimal. The workaround is to ensure that the ports on the standby cluster members are not in the spanning-tree blocking state.
The workaround is to use rate limiting on DHCP traffic to prevent a denial of service attack from occurring. The workaround is to power the access point by using an AC wall adaptor. The workaround is to enable PoE and to configure the switch to recover from the PoE error-disabled state. The workaround is to reduce the number of multicast routes and IGMP snooping groups to less than the maximum supported value. The switchport block multicast interface configuration command is only applicable to non-IP multicast traffic.
The workaround is to enter the clear ip mroute privileged EXEC command on the interface. After you configure a switch to join a multicast group by entering the ip igmp join-group group-address interface configuration command, the switch does not receive join packets from the client, and the switch port connected to the client is removed from the IGMP snooping forwarding table.
The workaround is to enter the shutdown and the no shutdown interface configuration commands on the Fast Ethernet interface of a new IP phone that is attached to the service module port after the internal link is brought up.
The workaround is to choose compatible buffer sizes and threshold levels. The workaround to this issue is to use an on-demand upgrade to upgrade switches in the stack by entering the vstack download config and vstack download image commands. You should also configure the tar image name instead of the image-list file name in the stored images. The workaround is to use the TFTP utility of another server instead of a Windows server or to manually delete the existing backup file before backing up again.
For clients to upgrade using Smart Install, you should configure product-id specific image and configuration files in the director. This is a hardware limitation. The workaround is to reduce the number of VLANs or trunks. The workaround is to enter the switchport access vlan dynamic interface configuration command separately on each port.
The workaround is to click Yes when you are prompted to accept the certificate. Catalyst S switches internally support up to 16 different control plane queues.
Each queue is dedicated to handling specific protocol packets and is assigned a priority level. For example, STP, routed, and logged packets are sent to three different control plane queues, which are prioritized in corresponding order, with STP having the highest priority. Each queue is allocated a certain amount of processing time based on its priority.
The processing-time ratio between low-level functions and high-level functions is allocated as 1-to Therefore, the control plane logic dynamically adjusts the CPU utilization to handle high-level management functions as well as punted traffic up to the maximum CPU processing capacity.
Basic control plane functions, such as the CLI, are not overwhelmed by functions such logging or forwarding of packets. If this message appears, check that there is network connectivity between the switch and the ACS. If this happens, enter the no auto qos voip cisco-phone interface command on all interface with this configuration to delete it. Then enter the auto qos voip cisco-phone command on each of these interfaces to reapply the configuration.
From the Settings window, choose Automatically. Click OK to exit the Internet Options window. If you are not using the default method of authentication the enable password , you need to configure the HTTP server interface with the method of authentication used on the switch. Configure the HTTP server interface for the type of authentication that you want to use.
The device manager uses the HTTP protocol the default is port 80 and the default method of authentication the enable password to communicate with the switch through any of its Ethernet ports and to allow switch management from a standard web browser. You should write down the port number through which you are connected. Use care when changing the switch IP information. The Bug Search Tool BST , which is the online successor to Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting.
The 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 tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
To view the details of a caveat listed in this document:. Enter the bug ID in the Search For: field. FNF Flow exporter source interface is not synchronized across switch stack members. Device is getting crashed on the "cts role-based enforcement". Double-free of VTY context causes a software-forced crash. Span config lost after reboot when using interface ranges.
Automate-tester does not send probes when the server is dead. NTP leap second addition is not working during leap second event. IOS Memory leak and possible crash when using a logging discriminator. Catalyst S MAC flapping and crash on unauth ports with auth control-direction in.

When creating a switch cluster or adding a switch to a cluster, follow these guidelines: When you create a switch cluster, we recommend configuring the highest-end switch in your cluster as the command switch.
If you are managing the cluster through Network Assistant, the switch with the latest software should be the command switch. The standby command switch must be the same type as the command switch.
