Upgrading the Switch Software
- Finding the Software Version and Feature Set
- Deciding Which Files to Use
- Archiving Software Images
- Upgrading a Switch by Using the CLI
- Recovering from a Software Failure
Finding the Software Version and Feature Set
The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. A subdirectory contains the files needed for web management. The image is stored on the compact flash memory card.
You can use the show version privileged EXEC command to see the software version that is running on your switch. The second line of the display shows the version.
You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.
Deciding Which Files to Use
The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file contains the Cisco IOS image file and the files needed for the embedded Express Setup. You must use the combined tar file to upgrade the switch through Express Setup. To upgrade the switch through the CLI, use the tar file and the archive download-sw privileged EXEC command.
ie3010-ipservicesk9-mz.152-2.E.bin ie3010-ipservicesk9-tar.152-2.E.tar6 |
Cisco IE 3010 IP Services cryptographic image with Layer 2 and Layer 3 features. |
Cisco IE 3010 LAN Base cryptographic image with all Layer 2 features, IPv4 static routing, and inter-VLAN routing. |
Archiving Software Images
Before upgrading your switch software, make sure that you have archived copies of the current
Cisco IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and until you have verified that the new Cisco IOS image works properly in your network.
Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more information:
http://www.cisco.com/en/US/prod/collateral/iosswrel/ps8802/ps6969/ps1835/prod_bulletin0900aecd80281c0e.html
You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command.
Note
Although you can copy any file on the flash memory to the TFTP server, it is time-consuming to copy all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and archive it on an internal host in your network.
You can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP server by using the tftp-server global configuration command. For more information about the tftp-server command, see the “Basic File Transfer Services Commands” section of the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 :
http://www.cisco.com/en/US/docs/ios/fundamentals/command/reference/cf_t1.html
Upgrading a Switch by Using the CLI
This procedure is for copying the combined tar file to the switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image.
Note Make sure that the compact flash card is inserted into the switch before downloading the software.
To download software, follow these steps:
Step 1 Use Table 3 to identify the file that you want to download.
Step 2 Download the software image file. If you have a SmartNet support contract, go to this URL, and log in to download the appropriate files:
http://www.cisco.com/cisco/web/download/index.html
To download the image for an IE 3010 switch, click Switches > Industrial Ethernet Switches > Cisco IE 3010 Series Switches, and then click on the Cisco IOS software for your specific switch model.
Step 3 Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP server is properly configured.
For more information, see Appendix B of the software configuration guide for this release.
Step 4 Log into the switch through the console port or a Telnet session.
Step 5 (Optional) Check that you have IP connectivity to the TFTP server by entering this privileged EXEC command:
For more information about assigning an IP address and default gateway to the switch, see the software configuration guide for this release.
Step 6 Download the image file from the TFTP server to the switch. If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command:
The /overwrite option overwrites the software image in flash memory with the downloaded one.
The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.
For // location, specify the IP address of the TFTP server.
For / directory / image-name .tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive.
This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch:
You can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option.
Installation Notes
You can assign IP information to your switch by using these methods:
- The Express Setup program, as described in the switch getting started guide.
- The CLI-based setup program, as described in the switch hardware installation guide.
- The DHCP-based autoconfiguration, as described in the switch software configuration guide.
- Manually assigning an IP address, as described in the switch software configuration guide.

Limitations and Restrictions
You should review this section before you begin working with the switch. These are known limitations that will not be fixed, and there is not always a workaround. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.
Configuration
This problem occurs under these conditions:
– When the switch is started without a configuration (no config.text file in flash memory).
– When the switch is connected to a DHCP server that is configured to give the switch an address. (The dynamic IP address is assigned to VLAN 1).
– When an IP address is configured on VLAN 1 before the dynamic address lease assigned to VLAN 1 expires.
The workaround is to reconfigure the static IP address. (CSCea71176 and CSCdz11708)
- When connected to some third-party devices that send early preambles, a switch port operating at 100 Mb/s full duplex or 100 Mb/s half duplex might bounce the line protocol up and down. The problem is observed only when the switch is receiving frames.
The workaround is to configure the port for 10 Mb/s and half duplex or to connect a hub or a nonaffected device to the switch. (CSCed39091)
- When port security is enabled on an interface in restricted mode and the switchport block unicast interface command has been entered on that interface, MAC addresses are incorrectly forwarded when they should be blocked
The workaround is to enter the no switchport block unicast interface configuration command on that specific interface. (CSCee93822)
There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. (CSCef59331)
- When the logging event-spanning-tree interface configuration command is configured and logging to the console is enabled, a topology change might generate a large number of logging messages, causing high CPU usage. CPU usage can increase with the number of spanning-tree instances and the number of interfaces configured with the logging event-spanning-tree interface configuration command. This condition adversely affects how the switch operates and could cause problems such as STP convergence delay.
High CPU usage can also occur with other conditions, such as when debug messages are logged at a high rate to the console.
– Disable logging to the console.
– Rate-limit logging messages to the console.
– Remove the logging event spanning-tree interface configuration command from the interfaces. (CSCsg91027)
The workaround is to configure aggressive UDLD. (CSCsh70244)
- When you enter the boot host retry timeout global configuration command to specify the amount of time that the client should keep trying to download the configuration and you do not enter a timeout value, the default value is zero, which should mean that the client keeps trying indefinitely. However, the client does not keep trying to download the configuration.
The workaround is to always enter a non-zero value for the timeout value when you enter the boot host retry timeout timeout-value command. (CSCsk65142)
- On a switch running both Resilient Ethernet Protocol (REP) and Bidirectional Forwarding Detection (BFD), when the REP link status layer (LSL) age-out value is less than 1 second, the REP link flaps if the BFD interface is shut down and then brought back up.
The workaround is to use the rep lsl-age-out timer interface configuration command to configure the REP LSL age timer for more than 1000 milliseconds (1 second). (CSCsz40613)
Ethernet
Traffic on EtherChannel ports is not perfectly load-balanced. Egress traffic on EtherChannel ports is distributed to member ports on a load-balance configuration, and traffic characteristics such as MAC or IP address.
More than one traffic stream might map to same member ports based on hashing results calculated by the ASIC. If this happens, uneven traffic distribution happens on EtherChannel ports.
Changing the load-balance distribution method or changing the number of ports in the EtherChannel can resolve this problem.
Use any of these workarounds to improve EtherChannel load balancing:
- For random source-ip and dest-ip traffic, configure the load-balance method as src-dst-ip.
- For incrementing source-ip traffic, configure the load-balance method as src-ip.
- For incrementing dest-ip traffic, configure the load-balance method as dst-ip.
- Configure the number of ports in the EtherChannel so that the number is equal to a power of 2 (that is, 2, 4, or 8)
For example, with load balance configured as dst-ip with 150 distinct incrementing destination IP addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is optimal. (CSCeh81991)
IP
When the rate of received DHCP requests exceeds 2,000 packets per minute for a long time, the response time might be slow when you are using the console.
The workaround is to use rate limiting on DHCP traffic to prevent a denial of service attack from occurring. (CSCeb59166)
QoS
- Some switch queues are disabled if the buffer size or threshold level is set too low with the mls qos queue-set output global configuration command. The ratio of buffer size to threshold level should be greater than 10 to avoid disabling the queue.
The workaround is to choose compatible buffer sizes and threshold levels. (CSCea76893)
- When auto-QoS is enabled on the switch, priority queuing is not enabled. Instead, the switch uses shaped round robin (SRR) as the queuing method. The auto-QoS feature is designed on each platform based on the feature set and hardware limitations, and the queuing method supported on each platform might be different.
SPAN and RSPAN
- Cisco Discovery Protocol (CDP), VLAN Trunking Protocol (VTP), and Port Aggregation Protocol (PAgP) packets received from a SPAN source are not sent to the destination interfaces of a local SPAN session.
The workaround is to use the monitor session session_number destination { interface interface-id encapsulation replicate} global configuration command for local SPAN. (CSCed24036)
Trunking
- IP traffic with IP options set is sometimes leaked on a trunk port. For example, a trunk port is a member of an IP multicast group in VLAN X but is not a member in VLAN Y. If VLAN Y is the output interface for the multicast route entry assigned to the multicast group and an interface in VLAN Y belongs to the same multicast group, the IP-option traffic received on an input VLAN interface other than the one in VLAN Y is sent on the trunk port in VLAN Y because the trunk port is forwarding in VLAN Y, even though the port has no group membership in VLAN Y.
There is no workaround. (CSCdz42909).
- For trunk ports or access ports configured with IEEE 802.1Q tagging, inconsistent statistics might appear in the show interfaces counters privileged EXEC command output. Valid IEEE 802.1Q frames of 64 to 66 bytes are correctly forwarded even though the port LED blinks amber, and the frames are not counted on the interface statistics.
VLAN
- If the number of VLANs times the number of trunk ports exceeds the recommended limit of 13,000, the switch can fail.
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
- When line rate traffic is passing through a dynamic port, and you enter the switchport access vlan dynamic interface configuration command for a range of ports, the VLANs might not be correctly assigned. One or more VLANs with a null ID appears in the MAC address table instead.
The workaround is to enter the switchport access vlan dynamic interface configuration command separately on each port. (CSCsi26392)
Important Notes
Express Setup Notes
- We recommend using this browser setting to speed up the time needed to display Express Setup from Microsoft Internet Explorer.
1. Choose Tools > Internet Options.
2. Click Settings in the Temporary Internet files area.
3. From the Settings window, choose Automatically.
5. Click OK to exit the Internet Options window.
- The HTTP server interface must be enabled to display Express Setup. By default, the HTTP server is enabled on the switch. Use the show running-config privileged EXEC command to see if the HTTP server is enabled or disabled.
Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:
- Express Setup 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.
If you change the HTTP port, you must include the new port number when you enter the IP address in the browser Location or Address field (for example, http://10.1.126.45:184, where 184 is the new HTTP port number). Write down the port number through which you are connected. Use care when changing the switch IP information.
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.
Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:
