Upgrading the Switch Software

These are the procedures for downloading software. Before downloading software, read these sections for important information:

n Finding the Software Version and Feature Set

n Deciding Which Files to Use

n Archiving Software Images

n Upgrading a Switch by Using the CLI

n Installation Notes

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 stored in flash memory. For example, use the dir flash: command to display the images in the 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 device manager. You must use the combined tar file to upgrade the switch through Express Setup. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.

Cisco IOS Software Image Files lists the filenames for this software release.

global configuration command to change the SDM template to a specific template. For example, if the switch uses Layer 3 routing, change the SDM template from the default to the routing template. You must reload the switch for the new template to take effect.

Archiving Software Images

Before upgrading your switch software, make sure that you archive copies of both your current Cisco IOS release and the Cisco IOS release to which you are upgrading. Keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and 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 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.

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.

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.

Make sure that the compact flash card is in the switch before downloading the software.

To download software, follow these steps:

1. Use Cisco IOS Software Image Files to identify the file that you want to download.

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://software.cisco.com/download/navigator.html

For example, to download the image for an IE 2000 switch, select Products > Switches > Industrial Ethernet Switches > Cisco Industrial Ethernet 2000 Series Switches, then select your switch model. Select IOS Software for Software Type, then select the image you want to download.

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 the “Assigning the Switch IP Address and Default Gateway” chapter in the applicable document listed in Methods for Assigning IP Information.

4. Log into the switch through the console port or a Telnet session.

5. (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC command:

Switch# ping tftp-server-address

For more information about assigning an IP address and default gateway to the switch, see Methods for Assigning IP Information.

6. Download the image file from the TFTP server to the switch.

— 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.

Important Notes

Device Manager and NAT Statistics

A NAT instance with translations that you create using the CLI is not reflected in the Device Manager > Monitor > Statistics > NAT statistics page. Only those instances that you create from the Device Manager GUI and that have translations are shown in the NAT instance statistics. (CSCum87971)

NAT “permit unmatched” allows ARP packets as long as the translation matches either IP source OR IP destination. (CSCup27591)

Limitations and Restrictions

Cisco recommends that you 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 for these issues. Some features might not work as documented, and some features might be affected by recent changes to the switch hardware or software.

n CSCup58174

Symptom CIP V4Router object does not display some metrics that show run | i route displays.

Example of behavior:

Workaround There is no workaround for this issue.

n CSCup75235

Symptom SFP types SFP-GE-L and GLC-EX-SMD sometimes generate Rx power high warning without significant traffic.

Conditions Insert SFPs ( SFP-GE-L and GLC-EX-SMD) into CGS 2520. You can sometimes observe that the Rx power high warning syslog message is generated at every monitoring interval.

If snmp-server enable trap transceiver is configured, a trap is also generated.

Workaround There is no workaround for this issue. The SFPs could have gone bad or the optical cable is bad. Observe the SFPs, cable and traffic, and if you find issues replace the SFPs.

There is no functionality issue observed under this condition. This seems to be a false positive.

n CSCus02105

Symptom show cip object v4router 0 does not display correct routes in some scenarios.

Conditions If you configure a cip unsupported route, for example, ip route 0.0.0.0 0.0.0.0 fa1/1 172.27.168.129, the route will not be displayed properly in the sh cip object v4router command output. All following routes (including supported routes such as ip route 0.0.0.0 0.0.0.0 fa1/1 or ip route 0.0.0.0 0.0.0.0 vlan1) also will not be displayed properly.

Workaround Reload the switch.

n CSCuw22362

Symptom The network-policy profile command is not supported on the IE 3010 in this release and earlier 15.x and 12.x Cisco IOS releases.

Conditions Entering the network-policy profile command on an IE 3010 indicates that it is an Unrecognized command.

Workaround There is no workaround. The IE 3010 does not support the command in this release.

Caveats

This section addresses the open caveats in this release and provides information on how to use the Bug Search Tool to find further details on those caveats. This section includes the following topics:

n Open Caveats

n Accessing Bug Search Tool

Open Caveats

n CSCuo87734

Symptom When a system is reloaded after its startup configuration has been erased, sometimes the vlan 1 interface goes to admin down state.

Conditions Boot a system with empty startup configuration.

Workaround Issue no shut on the vlan interface.

n CSCup53568

Symptom The system allows you to configure more than 16 routes, but they are not visible in the ip route table.

Conditions With the IE 2000 running the enhanced lanbase image and ip routing enabled, configure more than 16 routes. They are not visible in the ip route table or in show running-configuration. There is no error/warning message when you exceed the 16 route limit. Functionally there is no impact.

Workaround There is a CLI error message when the maximum number of static routes is exceeded. To see this error message, set the following debugging CLI: debug ip routing static db. When too many routes are configured, you will see the following messages on the console:

>Mar 30 23:49:09.912: IP-ST-DB(default): Maximum allowed static route count reached :16

>Mar 30 23:49:09.912: IP-ST-DB(default): ip_addstatic_route(), failed

>Mar 30 23:49:09.912: 10.0.0.15/32 via 3.3.3.1 ,tag 0,fg 0x40020004,dis 1,name ,lfg 0x0,own M

n CSCuq16134

Symptom CPU protection and dot1x are mutually exclusive. When enabled, these features work fine. When the IE 2000U or CGS 2520 have TrustSec configured to work with ISE, dot1x fails to authenticate.

Conditions CPU protection is enabled.

Workaround Disable CPU protection by running the following command: no policer cpu uni all.

n CSCuq21005

Symptom In-line editing becomes unresponsive on the Device Manager Port Thresholds page.

Conditions Editing a field too quickly can cause in-line editing to become unresponsive.

Workaround Editing the box repeatedly works if the user waits one or two seconds for Device Manager to push the update to the device.

n CSCuq43566

Symptom Unsupported vlan v4r cip object configuration causes issues.

Conditions If you configure a route with a vlan interface as the next hop, it affects the display of other routes in the v4r output.

Workaround Remove all vlan routes in order to view the routes configured after the vlan v4r configuration. CIP does not support vlan for static routes.

n CSCuq49187

Workaround There is no workaround for this issue.

n CSCuq63574

Symptom Per port per vlan policer feature is not present on the IE 2000.

Conditions The IPlite license is applied.

Workaround There is no workaround for this issue.

n CSCuq63577

Symptom Match Input interface option cannot be configured while configuring class map.

Conditions The IPLite license is applied.

Workaround There is no workaround for this issue.

n CSCuq64362

Symptom QoS VLAN-based and hierarchical queuing is not configurable on the IE 2000.

Conditions The IPLite license is applied.

Workaround There is no workaround for this issue.

n CSCuq72745

Symptom On the IE 3010, the GE port shows speed as 100Mbps when another GE port is connected.

Conditions While generating traffic with IXIA, 90% packet drop is seen.

Topology:

IXIA-------(GE)IE3010-(GE)-----(GE)-IE2K(GE)----- IXIA

Steps to reproduce:

1. Connect the UUTs on GE ports using 100 MB SFP & RJ 45.

2. Ensure that the port comes up using the SFP.

3. Change the media type to RJ45.

4. The port still displays the speed as 100 Mbps.

5. Pass end to end L2 line rate traffic using IXIA.

6. 90% packet loss is seen.

Workaround Issue a shut and no shut on the interface.

n CSCuq73660

Symptom The CLI to configure NAC L2 IP is not available.

Conditions The IPLite license is applied.

Workaround There is no workaround for this issue.

n CSCur00491

Symptom Not able to configure the input alarm 3 and 4 in CGS2520 and IE3010 devices from the CLI (Relay, Notifies, and Syslog options)

Conditions Input alarms 3 and 4 appear to be enabled in show alarm settings output but the settings are not retained after reloading the device.

Workaround There is no workaround for this issue.

n CSCur01466

Symptom Sometimes a memory leak can be seen originating from psecure_vlan_info_find.

Conditions The leak is occasionally seen when a user tries to enable port-security with a duplicate MAC address and receives an error.

Workaround Reload the system.

n CSCur21110

Symptom The VLAN Access List (VACL) feature cannot be configured on the IE 2000.

Conditions The IPLite license needs to be enabled.

Workaround There is no workaround for this issue.

n CSCur24288

Symptom On the Cisco IE 2000 and IE 3000, the GetAttList time sync obj 0x43 Reply sequence is inconsistent with the request.

Conditions Get Attributes List was executed against the time sync object in the IE switches. The sequence was explicitly specified with attributes of variable size at the end in order to simplify parsing the reply. While the CIP specification does not explicitly require that the reply follow the sequence of the request, this is the typical (and therefore expected) behavior in released products so far observed.

The initial sequence attempted was

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 18, 19, 20, 27, 28, 12, 13

However the reply sequence received was

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 18, 19, 20, 27, 28

To verify this, a get attributes list with sequence was attempted

5, 4, 3, 2, 1, 6, 7, 8, 9, 10, 11, 18, 19, 20, 27, 28, 12, 13

However the reply sequence received was

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 18, 19, 20, 27, 28

Workaround There is no workaround for this issue.

n CSCur45858

Symptom Cisco MAC notification MIB entries are not reported correctly.

Conditions cmnUtilizationUtilization.1001 = 4194258 << This entry is percentage. It is showing > 100.

The Value is shown higher on a device when the mac address entries reach the maximum value.

On another device the value is shown by default as the one above.

Also the cmnUtilizationTable (5) is always shown as zero.

Workaround There is no workaround for this issue.

n CSCur62153

Symptom Logging out of Device Manager in the IE browser terminates all tab sessions. The user must log in again to any web application sessions that were terminated.

Conditions This issue occurs only with the IE browser.

Workaround Use the Firefox browser.

n CSCus18066

Symptom Profinet DCP (Dynamic Configuration Protocol) discovery and config download do not work consistently.

Conditions Siemens STEP7 DCP tool may not be able to discover the device MAC address.

Workaround Reboot the switch.

n CSCvd25567

Symptom Inserting GLC-FE-T-I SFP puts FE ports of IE2000 unit in err-disable state

Conditions The issue affects certain IE2000 SKU types on which the issue is always present. There are no pre-conditions.

Affected Cisco SKUs:

IE-2000-4TS-L (on uplinks)

IE-2000-4TS-B (on uplinks)

IE-2000-8TC-L (on uplinks)

IE-2000-8TC-B (on uplinks)
