Upgrading the Switch License

You can upgrade Cisco IOS software features through the Cisco Software Activation tool. It authorizes
and enables the feature set on Cisco IE 2000 switch series. Based on the type of license, it allows you to
enable certain features through the licensing upgrade or both licensing and software upgrade. On Cisco
IE 2000 switches, to upgrade from LAN Lite to LAN Base you do not require new software releases.
However, to upgrade from LAN Base to Enhanced LAN Base for NAT, you require both software and
license upgrades. See

Software Activation Licensing Upgrade

for detailed steps:

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 also can use the

dir

filesystem

privileged EXEC command to see the directory names of other

software images that you might have stored in flash memory.

NEW DOC # PENDING

Upgrading the Switch Software

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.

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

Cisco IOS Configuration Fundamentals Command

Reference

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 on page 8

to identify the file that you want to download.

Installation Notes

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 a Cisco IE 2000 switch, click

Switches > Industrial Ethernet Switches >

Cisco IE 2000 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:

Switch#

ping

tftp-server-address

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:

Switch#

archive download-sw /overwrite /reload tftp:

[[//

location

directory

image-name

.tar

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:

Switch#

archive download-sw /overwrite tftp://198.30.20.19/

image-name

.tar

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.

Recovering from a Software Failure

For additional recovery procedures, see the “Troubleshooting” chapter in the software configuration
guide for this release.

Installation Notes

You can assign IP information to your switch by using these methods:

•

Express Setup program, as described in the switch getting started guide.

Release Notes for the Cisco IE 2000 Switches, Cisco IOS Release 15.2(1)EY

NEW DOC # PENDING

Software Features

•

CLI-based setup program, as described in the switch hardware installation guide.

•

DHCP-based autoconfiguration, as described in the switch software configuration guide.

•

Manual assignment of an IP address, as described in the switch software configuration guide.

Software Features

Digital Optical Monitoring

Digital Optical Monitoring (DOM) is supported when using a DOM-capable SFP transceiver module.
For information about the switch models that have SFP or dual-purpose ports, see

Switch Models

Supported, page 3

. For information about DOM-capable SFP modules, see

SFP Modules Supported,

page 5

Note

DOM is not supported on downlink SFP ports.

DOM allows monitoring real-time parameters of the switch, such as optical input and output power,
temperature, laser bias current, and transceiver supply voltage. These parameters are monitored against
the threshold values. The real-time DOM parameters can be monitored using command line interface or
SNMP interface.

DOM is possible only with DOM-capable transceiver modules. When using an SFP module in a dual
purpose port, DOM is supported if the interface media type is configured to SFP or if global transceiver
monitoring is enabled.

Transceiver monitoring is enabled by default.

Precision Time Protocol (PTP)

Several enhancements were made to improve the implementation of Precision time Protocol (PTP).

•

End-to-End Transparent Clock (E2E TC) now supports at least 300 PTP messages per second. The
previous capacity was 10 - 20 PTP messages per second. The E2E TC timing performance also was
enhanced to frequency lock to the GMC, thereby reducing timing errors.

•

With the recommended settings, the Boundary Clock now supports eight clocks in a chain
(previously became unstable with four clocks). The timing performance also was enhanced to
improve stability and precision. Cisco recommends setting the logDelReqInterval to -2 (-2 to 6
supported) and the logSyncInterval to -1 (-1 to 1 supported) for chains of Boundary Clocks. The PTP
Clock must receive 50 Sync messages and 6 DelReq messages for a port to leave the
UNCALIBRATED state.

•

Added support for PTP management messages, such as example: CLOCK_DESCRIPTION, as
defined in Clause 15 of IEEE Std 1588-2008. These management messages are mandatory for CIP/
ODVA compliance.

Limitations and Restrictions

Security Group Tag Exchange Protocol for Cisco TrustSec

Cisco Industrial Ethernet switches now can participate in the Cisco TrustSec security architecture by
using the SGT Exchange Protocol (SXP). Cisco TrustSec establishes domains of trusted network
devices. After a device is authenticated, communication is secured by using encryption and other
mechanisms. As packets enter the network, they are classified by security group tags (SGTs) for the
purpose of applying security policies. SXP is used to propagate the SGTs across network devices, such
as the IE switches, that do not have hardware support for Cisco TrustSec.

To use this feature, enable SXP and configure the connections on each device that needs to participate
in SXP exchanges.

•

Enable SXP by entering the

cts sxp enable

command in global configuration mode.

•

Configure each SXP connection by specifying the peer’s IP address, the password, and the role. For
role, you can specify which device is the “speaker” and the “listener” in the exchange.

For detailed information about the configuration commands and show commands, see “SGT Exchange
Protocol over TCP (SXP)” at

http://www.cisco.com/en/US/partner/docs/switches/lan/trustsec/

configuration/guide/sxp_config.html#wp1056896

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.

Cisco IOS Limitations

•

Ethernet

•

QoS

•

RADIUS

•

SPAN and RSPAN

•

Spanning Tree Protocol

•

Trunking

•

VLAN

Ethernet

•

Traffic on EtherChannel ports is not perfectly load-balanced. Egress traffic on EtherChannel ports
are distributed to member ports on load balance configuration and traffic characteristics like MAC
or IP address. More than one traffic stream may map to same member ports based on hashing results
calculated by the ASIC.

If this happens, uneven traffic distribution will happen 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:

Release Notes for the Cisco IE 2000 Switches, Cisco IOS Release 15.2(1)EY

NEW DOC # PENDING

Limitations and Restrictions

–

for random source-ip and dest-ip traffic, configure load balance method as

src-dst-ip

–

for incrementing source-ip traffic, configure load balance method as

src-ip

–

for incrementing dest-ip traffic, configure 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
(i.e. 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)

•

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 mechanism. The auto-QoS feature is designed on each
platform based on the feature set and hardware limitations, and the queuing mechanism supported
on each platform might be different. There is no workaround. (CSCee22591)

RADIUS

•

RADIUS change of authorization (COA) reauthorization is not supported on the critical auth
VLAN.

There is no workaround. (CSCta05071)

SPAN and RSPAN

•

When the RSPAN feature is configured on a switch, Cisco Discovery Protocol (CDP) packets
received from the RSPAN source ports are tagged with the RSPAN VLAN ID and forwarded to trunk
ports carrying the RSPAN VLAN. When this happens a switch that is more than one hop away
incorrectly lists the switch that is connected to the RSPAN source port as a CDP neighbor.

This is a hardware limitation. The workaround is to disable CDP on all interfaces carrying the
RSPAN VLAN on the device connected to the switch. (CSCeb32326)

•

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)

Release Notes for the Cisco IE 2000 Switches, Cisco IOS Release 15.2(1)EY

NEW DOC # PENDING

Important Notes

Spanning Tree Protocol

•

CSCtl60247

When a switch or switch stack running Multiple Spanning Tree (MST) is connected to a switch
running Rapid Spanning Tree Protocol (RSTP), the MST switch acts as the root bridge and runs
per-VLAN spanning tree (PVST) simulation mode on boundary ports connected to the RST switch.
If the allowed VLAN on all trunk ports connecting these switches is changed to a VLAN other than
VLAN 1 and the root port of the RSTP switch is shut down and then enabled, the boundary ports
connected to the root port move immediately to the forward state without going through the PVST+
slow transition.

There is no workaround.

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 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.

There is no workaround. (CSCec35100).

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 assigned

correctly. 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)

•

When many VLANs are configured on the switch, high CPU utilization occurs when many links are
flapping at the same time.

The workaround is to remove unnecessary VLANs to reduce CPU utilization when many links are
flapping. (CSCtl04815)

IPv4 Static Routing Notes

Cisco IE 2000 supports IPv4 static routing in the LAN Base image. To access static routing commands,
you need to change the SDM template from the default template to lanbase-routing, followed by a switch
reload sequence.

61000-4-3 Standard Notes

The following note is an update to the

Regulatory Compliance and Safety Information

(RCSI) guide.

This note applies to the 61000-4-3 standard listed in the “EMC Interface Immunity” section of Table 1
of the guide.

Note

To meet 10V/m or 20V/m Radiated Immunity levels, shielded cables must be used on the uplink ports,
G1/1 and G1/2.

This note applies to these SKUs:
– IE-2000-4T-G-L
– IE-2000-4T-G-B
– IE-2000-8TC-G-L
– IE-2000-8TC-G-B

Important Notes

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

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:

Note

IE-2000-4S-TS-G do not have copper ports for PC, a GLC-T copper SFP is required to perform express
setup.

The

show l2nat statistics

command

shows that total packets is less than the

translated packets after running the traffic for few days.

Work Around:

There is no workaround.

CSCuh36550

When

power inline wattage max

value

is configured at the global

configuration level. The switch will print the error messages during boot up if

value

is not the default value (65 watts)

There is no operational impact and there is no workaround

CSCtx35101

The password must be entered twice before it is accepted in Express Setup.

Work Around:

There is no workaround.

CSCum76147

No warning for Port Security Settings changes displayed via Device Mgr.

Work Around:

There is no workaround.

CSCum67722

Maximum mac address range should vary according to the SDM template
settings on the Eiskaffee. Maximum unicast mac address range is not similar to
CLI. In Eiskaffee for all the SDM template its shows as 8192 as maximum mac
range, which is incorrect.

Work Around:

There is no workaround.
