Release Notes for the Catalyst 2900 Series XL and Catalyst 3500 Series XL Switches,
Cisco IOS Release 12.0(5.4)WC(1)


August 28, 2001

Cisco IOS Release 12.0(5.4)WC(1) runs on Catalyst 2900 series XL and Catalyst 3500 series XL switches with 8-MB CPU DRAM. This release also runs on Catalyst 2900 series LRE XL switches with 16-MB CPU DRAM. This release does not run on Catalyst 2900 series XL switches with 4-MB CPU DRAM.

These release notes include important information about this IOS release and any limitations, restrictions, and caveats that apply to it. See the "Related Documentation" section for the complete list of Catalyst 2900 XL and Catalyst 3500 XL documentation.


Note Before upgrading your switch to this release, read the "Upgrading the Switch Software" section. If you are upgrading a Catalyst 2900 LRE XL switch, do not use the upgrade procedures in the Release Notes for the Catalyst 2900 Series XL and Catalyst 3500 Series XL Cisco IOS Release 12.0(5)WC(1). Instead, use the procedures in the "Using the CLI to Upgrade a Catalyst 2900 LRE XL Switch" section.


This IOS release is part of a special release of Cisco IOS software that is not released on the same 8-week maintenance cycle that is used for other platforms. As maintenance releases and future IOS releases become available, they will be posted to Cisco.com in the Cisco IOS software area.

Note In CMS, Internet Explorer versions 4.01 and 5.0 do not display edge devices that are not connected to the command switch. Other functionality is similar to that of Netscape Communicator.



Note If you receive an Internet Explorer error message that the page might not display correctly because your security settings prohibit the ActiveX controls, your security settings are set too high. To lower security settings, go to Tools > Internet Options, and select the Security tab. Select the indicated Zone, and move the Security Level for this Zone slider from High to Medium (the default).


To access CMS, follow the procedures in the "Initial Switch Configuration" section.

Cluster Requirements and Guidelines

This section describes the hardware and software requirements for clustering Catalyst desktop switches.

Catalyst 2900 XL and Catalyst 3500 XL Switches and Modules

Some versions of IOS software do not support clustering, and other versions do not support some of the features in this release. To ensure that all cluster switches are using the same software level, we recommend that you upgrade all cluster switches to the software release that supports the features that you want.

If you have a cluster with switches that are running different versions of IOS software, changes on the latest release might not be reflected on switches running the older versions. For example, if you start Visual Switch Manager (VSM) on a switch running Release 11.2(8)SA6, the windows and functionality can be different from a switch running Release 12.0(5)XU or later.

Table 6 describes the Catalyst 2900 XL and Catalyst 3500 XL switches supported by this release and shows which switches can be command switches. All switches can function as standalone devices.

All Catalyst 2900 XL and Catalyst 3500 XL switches running Cisco IOS Release 12.0(5.3)WC(1) and later are cluster-capable. All Catalyst 2900 XL modules are supported in cluster configurations.

New Features in this Release

This section describes the new features in this release.

"New Hardware Support" section

"New Software Support" section

New Hardware Support

This release supports the following new devices:

Catalyst 2900 LRE XL switches

Catalyst 2950 switches

Cisco 575 LRE CPE devices

New Software Support

This release supports the following new software features:

LRE technology—LRE is the technology that the Catalyst 2900 LRE XL switches use to transfer data and voice traffic through existing telephone lines (categorized and noncategorized unshielded twisted-pair cable) in multidwelling or tenant buildings. The LRE ports on these switches connect the Cisco 575 LRE CPE and the Cisco LRE 48 POTS Splitter (PS-1M-LRE-48). The link between a switch LRE port and CPE can provide up to 15 Mbps of bandwidth to remote Ethernet devices at distances of up to 4921 ft (1500 m).

Multicast VLAN Registration (MVR)—MVR is designed for applications using wide-scale deployment of multicast traffic (for example, broadcast of multiple television channels) across an Ethernet ring-based service provider network. MVR allows a subscriber on a port to subscribe and unsubscribe to a multicast stream on the network-wide multicast VLAN. It allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. It can continuously send multicast streams in the multicast VLAN, but, for bandwidth and security reasons, can isolate the streams from the subscriber VLANs.

Limitations and Restrictions

You should review this section before you begin working with the switches. Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.

Regardless of the switch model, only 64 instances of STP are supported.

When connecting to the Catalyst 3524-PWR XL 10/100 inline-power ports, observe the following caution:


Caution A Catalyst 3524-PWR XL 10/100 port needs up to 10 seconds to initially detect, power, and link to a Cisco IP Phone. If you disconnect the Cisco IP Phone before link has been established, you must wait 10 seconds before connecting another network device (other than another Cisco IP phone) to that switch port. Failing to do so can damage that network device.

The Cisco RPS 300 Redundant Power System supports the Catalyst 2900 LRE XL switches and the Catalyst 3524-PWR XL switch. When the RPS LED on the switch is amber, the RPS is connected but down. However, this might merely indicate that the RPS is in standby mode. Press Standby/Active on the RPS to put it into active mode. Refer to the RPS 300 Hardware Installation Guide for more information. You can view the RPS status by using the show rps privileged EXEC command.

You can connect the switch to a PC by using the switch console port and the supplied rollover cable and the DB-9 adapter. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) with this RJ-45-to-DB-25 female DTE adapter from Cisco.

Certain combinations of port features create configuration conflicts. Refer to the "Avoiding Configuration Conflicts" section in the "Troubleshooting" chapter of the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide for a table that defines these conflicts.

Host names and Domain Name System (DNS) server names that contain commas on a cluster command switch, member switch, or candidate switch can cause CMS to behave unexpectedly. You can avoid this instability in the interface by not using commas in host names or DNS names. Do not enter commas when also entering multiple DNS names in the IP Configuration tab of the IP Management window in CMS.

A configuration conflict occurs if a switch cluster has Catalyst 2900 LRE XL switches using both private and public profiles. If one LRE switch in a cluster is assigned a public profile, all LRE switches in that cluster must have that same public profile. Before you add an LRE switch to a cluster, make sure that you assign it the same public profile used by other LRE switches in the cluster.

The range of seconds for the span-tree max-age global configuration command is now 6 to 200 seconds. If you had used this command in Release 11.2(8)SA6 or earlier to set a value greater than this range and now upgrade your software to Release 11.2(8.1)SA6 or later, the switch sets this value to the default: 20 seconds for IEEE STP and 10 seconds for IBM STP.

All Catalyst 3500 series XL and most Catalyst 2900 series XL switches support a total of 250 VLANs and 64 STP instances. The Catalyst 2912 XL, 2924 XL, and 2924C XL switches support a total of 64 VLANs and 64 STP instances.

When using the SPAN feature, the monitoring port receives copies of sent and received traffic for all monitored ports. If the monitoring port is 50 percent oversubscribed for a sustained period of time, it will probably become congested. One or more of the ports being monitored might also experience a slowdown.

When using the Software Image Management (SWIM) application in the Resource Manager Essentials (RME) suite of the CiscoWorks2000 product family to perform automated system software and boot loader upgrades, you should note the following:

Catalyst 2900 series XL switches require Release 11.2(8)SA4 or later and RME version 2.1 or 2.2.

Catalyst 3500 series XL switches require Release 11.2(8.1)SA6 or later and RME version 2.2.

Caveats

This section describes open and resolved caveats in Cisco IOS Release 12.0(5.4)WC(1):

Open Caveats

This section describes possible unexpected activity by Cisco IOS Release 12.0(5.4)WC(1):

CSCdt67450

Alignment and collision Ethernet counters on the Cisco 575 LRE CPE device are not reliable. These counters can increment without an Ethernet link, and they can also be higher than expected when encountering alignment and collision conditions. This is especially noticeable if an LRE port is configured with the LRE-15, the Public-ANSI, or the Public-ETSI profiles.

There is no workaround.

CSCdt22573

If a port group is set up between the LRE port of a Catalyst 2900 LRE XL switch and the FEC ports of another switch through the LRE CPE devices, and the LRE link on an LRE port drops, the LRE switch no longer uses the LRE port for data transmission. However, the other switch might continue sending data through the FEC port. The packets being sent to the LRE port of the LRE switch are lost.

If the LRE link is restored, data transmission continues as normal.

There is no workaround.

CSCdt01392

Ethernet statistics that appear in the output of the show interface command for LRE ports show the counters of the MAC on the switch instead of the MAC on the CPE device.

The workaround is to use the show controllers ethernet-controller command to see the Ethernet statistics on the CPE device. To clear the Ethernet statistics counters on the CPE device, use the clear controllers ethernet-controller command.

CSCdt53253

If a port on a switch is configured as a dot1q trunk, and the switch is receiving dot1q frames that have the cfi bit set in the dot1q header, the switch drops these frames. Depending on the number of frames that are received with this bit set, there can be a loss of connectivity to the switch.

The workaround is to prevent dot1q frames with the cfi bit set from being sent to the switch.

CSCdt83042

High rates of traffic sent to a MAC address that is used by an MVR multicast group and received on an MVR receiver port can cause excessive CPU utilization rates and consume enough resources on the switch CPU so that normal-spanning tree processing is interrupted. This can prevent spanning tree loops from being broken.

The workaround is to enable multicast storm control on all MVR receiver ports.

CSCdt84379

The connection between a switch and a console is lost whenever VLAN membership changes on an MVR port.

The workaround is to either Telnet to the switch to access the CLI or to reboot the switch to restore the console session.

CSCdt83966

When the receiver VLAN is shut down locally, suspended throughout the VTP domain, or deleted from the VTP database, the show mvr, show mvr int, and show mvr member commands do not show that MVR and its members are disabled. The receiver ports remain as MVR ports, and forwarding of MVR traffic resumes after the VLAN is restored and spanning tree has transitioned to a forwarding state.

When the multicast VLAN is shut down, suspended, or deleted, source ports configured as access ports are affected in much the same way that receiver ports are affected by the removal of the receiver VLAN. If the multicast VLAN is shut down, suspended, or deleted, source ports that are trunk ports are removed from MVR. After the VLAN is restored, these source ports must be manually added to MVR.

A workaround for the ports not being removed automatically from MVR is to manually remove any MVR source access ports or receiver ports that were configured in a VLAN that has been removed. You can do this by using the no mvr type [receiver | source] interface configuration command.

There is no workaround for the fact that these interfaces will be listed as active when the mvr show commands are used, even though the interface is down.

CSCdt84558

In MVR, when changing the configuration of a port from receiver to source, the port does not start receiving multicast traffic.

The workaround is to save the configuration and reboot the switch to restore proper traffic flooding.

CSCdt83212

MVR does not initialize on a switch if that switch is a cluster member and does not have an IP address.

The workaround is to set an IP address on the switch.

CSCdu10578

If an IGMP general query is received on a port that is assigned to a VLAN, but that port is not the receiver port VLAN, the query interrupts the multicast streams controlled by MVR in the multicast VLAN and receiver port.

The workaround is to make sure that no IGMP queries are sent to those VLANs.

CSCdt42854

Running a CMS link graph for more than 24 hours can cause an OutOfMemoryExeception error.

There is no workaround.

CSCdt47877

When running CMS with Windows 98 and JRE plug-in 1.3, the tooltip box that shows the exact coordinates of a point on a graph is so small that it is unreadable.

There is no workaround.

CSCdt58668

Checking the Logarithmic Scaling check box in the Link Graph window has no effect if the Total Byts, Total Packets, or Total Errors boxes are plotted.

There is no workaround.

CSCds86420

If you select a switch in the tree by using Cluster Management and choose Console Baud Rate, the baud rate dialog appears with the selected switch in the Selected Device list. If you then click cancel and select Console Baud Rate again, two identical items for the same switch are listed.

There is no workaround.

CSCdt48569

If you configure VLAN1 as the management VLAN and configure it as administratively down, VLAN1 correctly appears as administratively down in the output of the show ip interface brief command. If you configure any VLAN other than VLAN1 as the management VLAN and configure VLAN1 as administratively down, VLAN1 incorrectly appears as up in the output of the show ip interface brief command.

There is no workaround.

CSCdt57346

When you use the show rmon history command, the value for the collision is cumulative, not unique for each sample. The value for a collision in a given sample can be calculated by subtracting from the previous sample.

There is no workaround.

CSCds72421

If you shut down the management VLAN on VLAN1 on a Catalyst 2950 switch, set the management VLAN to 999, and then again use the shutdown command to shut down VLAN1, the IP address of VLAN 999 does not appear in the show cdp neighbor detail command display on a connected device.

The workaround is to reboot the switch.

CSCdt48011

Two problems occur when the Catalyst 2950 switch is in transparent mode:

If the switch is a leaf switch, any new VLANs added to it are not propagated upstream through VTP messages. As a result, the switch does not receive flooded traffic for that VLAN.

If the switch is connected to two VTP servers, it forwards their pruning messages. If the switch has a port on a VLAN that is not requested by other servers through their pruning messages, it does not receive flooded traffic for that VLAN.

There is no workaround.

CSCdt04001

On Catalyst 2900 XL and 3500 XL switches, when you change the privilege level for the interface, you can execute commands with the newly configured privilege level. However, the switch does not save the arguments associated with the command, and after a reload, the configured commands are not executable.

There is no workaround.

CSCdt49955

CMS dialogue windows can display two list selection boxes with Add and Remove buttons between them. If you press the Shift key on the keyboard at the same time as either Add or Remove, sometimes an exception error occurs. The exception error is displayed only inside the Java console window and is not displayed by CMS. As a result, the Add or Remove buttons might not function correctly. If you continue to click these buttons, multiple entries are added to the available or selected lists.

The workaround is to not hold down the Shift key when clicking Add or Remove.

CSCdt82729

If you launch the VMPS Configuration window from the device pop-up menu in Visual Switch Manager (VSM), it displays incorrect information.

The workaround is to not launch the VMPS Configuration window from the device popup menu, as VLAN Membership Policy Server (VMPS) is not supported on the Catalyst 2950 switches.

CSCdt68204

If you continuously ping a switch from a PC and the links from the switch to the network are brought down, when the link from the switch to the network is restored, pinging does not resume.

The workaround is to enter the clear cam command.

CSCdt18106

If you enter the snmpwalk command on the CISCO-IP-STAT-MIB, continuous loops occur through the first element in the MIB tree when IP accounting precedence is configured for a VLAN interface other than VLAN1.

The workaround is to use individual snmpget requests to retrieve data.

CSCdt48351

The usage of the c2950BandwidthUseage MIB always shows zero, instead of displaying the current bandwidth usage statistics.

There is no workaround.

CSCdt57171

On a Catalyst 3524 XL-PWR switch running Cisco IOS 12.0(5.2)XU, if an IP phone is connected to a Fast Ethernet port that is set to 10 Mbps half duplex and the switch is powered on and off, the IP phone does not power up.

The workaround is to disconnect the Ethernet cable and then reconnect it.

CSCds84479

When you connect two switches by GigaStack GBICs and you manually set duplex mode to full duplex or to autonegotiate on both ends, the link sometimes does not stabilize.

The workaround is to remove and reinsert one of the GBICs.

If the switch gets configured from the dynamic IP pool, a duplicate or different IP address might be assigned.

The workaround is to make sure that the DHCP server contains reserved addresses that are bound to each switch by the switch hardware address so that the switch does not obtain its IP address from the dynamic pool.

CSCdp67822

Cluster Management Suite requires a Java plug-in from Sun Microsystems. If you are using Internet Explorer and you disable Java plug-ins by using the Java Plug-In Control Panel, the initial Splash screen shows that the plug-in and Java are enabled, but Internet Explorer fails.

The workaround is to not disable Java plug-ins on the Java Plug-In Control Panel.

CSCdp82224

The Cluster Manager System Time Management window supports the configuration of the Network Time Protocol (NTP) and system time. When you make changes on this window from a command switch, Java propagates the changes to all cluster members. A conflict can arise if you configure NTP and also use the Set Daylight Saving Time and Set Current Time tabs.

The workaround is to either set the system time for the entire cluster on the command switch or configure NTP on the command switch to use an NTP server to provide time to the cluster. Do not use both methods at the same time.

CSCdm24487

The serial port shares the same status bit for hardware flow control and for ready.

The workaround is to not use flow control on the console port.

CSCdp70389

When you change the management VLAN on a cluster with command-switch redundancy enabled, the cluster can break if HSRP is configured on any of the cluster members in the new management VLAN.

The workaround is to not change the management VLAN to a VLAN where a member is configured as part of a standby group.

CSCdp85954

Root guard is inconsistent when configured on a port that is in the STP blocked state at the time of configuration.

There is no workaround.

CSCdp85928

CMS can behave unexpectedly if host names or DNS server names that it processes contain commas. This means that host names or DNS server names on a cluster command switch, member, or neighbor can cause instability in the HTML interface.

The workaround is to not include commas in host names or DNS server names in CMS.

Resolved Caveats

The following problems were resolved in Cisco IOS Release 12.0(5.4)WC(1):

CSCdu38771

When MVR is enabled and the MVR VLAN has been configured on a Catalyst 3508 XL switch, and at least one port has been set up as a receiver port, the switch no longer fails.

CSCdu38191

Cisco Discovery Protocol (CDP) packets that are sent out on Long Reach Ethernet ports now include the voice VLAN type-length-value (TLV) in their advertisements. An IP phone that is connected through a Cisco 575 LRE CPE device now sees the call center application running on the LRE switch.

CSCdt80748

When an ASIC does not pass the power-on self-test (POST) due to a built-in self-test (BIST) failure, an IOS error message now appears, and the ASIC is not initialized.

CSCdt87382

A Catalyst 2900 XL or 3500 XL switch no longer sends DHCP request packets every 4.5 seconds if no IP address is configured on interface VLAN 1.

CSCdt95269

The Cross-stack UplinkFast feature no longer takes 10 to 15 seconds to recover from a failed link when the management VLAN is configured for a non-default VLAN.

CSCds32999

A Catalyst 3500 XL switch that receives a 64- or 66-byte 802.1q encapsulated frame on a trunk port no longer counts the frame as a runt.

CSCdu21009

A switch now saves and uses a gateway address that it learns from a DHCP server.

CSCdu26425

After the no shutdown command is entered for an interface that is connected to a PC and STP is disabled on the VLAN to which that port belongs, frames are forwarded to that interface.

CSCdt78498

The switchports in a VLAN are no longer disabled after the MTU of that VLAN is changed to a value greater than 1500 bytes in the VLAN database.

CSCdt59751

The no snmp-server enable traps snmp [authentication] command now prevents authentication failure traps from being sent to the NMS.

CSCdt81996

When the sh line command is run from a console or vty session, the error message SCHED-3-UNEXPECTEDEVENT error for Exec process no longer appears.

CSCdu47718

A switch configured for Cross-stack UplinkFast that has failed over to a backup link no longer loses connectivity when the primary link is restored.

CSCdr95761

When configuring a switch using the switchport trunk command, and a line of text exceeds 80 characters, the text is now parsed correctly by IOS.

CSCdt83279

An MVR receiver port that receives multicast data traffic exceeding the configured threshold does not shut down. The MVR threshold feature was removed in Release 12.0(5.3)WC(1). Use the port multicast storm control feature instead of the MVR threshold feature to limit rates.

CSCdt86565

The MVR threshold feature causes switch ports to be shut down when creating MVR groups. The MVR threshold feature was removed in Release 12.0(5.3)WC(1).

CSCdt84379

The connection between a switch and console is no longer lost when VLAN membership changes on an MVR port.

CSCdt26961

The power inline never command now correctly changes the link pulse from a power link pulse to a standard link pulse.

CSCds78577

If a client is moved from one secure port to another, and the maximum secure address count on the second port is exceeded, the switch now sends security violation traps.

CSCdt39268

Cisco IOS software now prevents the successful prediction of TCP Initial Sequence Numbers.

CSCdt13828

When a loopback command is followed by a no loopback command on a port connected to a device, such as an Ethernet time clock, that port now correctly comes out of loopback.

Important Notes

This section describes important information related to this release.

The MVR threshold feature has been removed from Release 12.0(5.3)WC(1). Use the port multicast storm control feature instead of the MVR threshold feature to limit rates.

In this release, when you are configuring a cascaded stack of Catalyst 3500 XL switches by using a GigaStack GBIC and want to include more than one VLAN in the stack, be sure to configure all the GigaStack GBIC interfaces as trunk ports by using the switchport mode trunk interface configuration command and to use the same encapsulation method by using the switchport encapsulation {isl | dot1q} interface configuration command. For more information about these commands, refer to the command reference publication for your switch.

Three Long-Reach Ethernet (LRE) profiles were added to this release and are not documented in the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide and CMS online help:

LRE-5LL

LRE-10LL

LRE-15LL

The PUBLIC-ANSI, PUBLIC-ETSI, LRE-5, LRE-10, and LRE-15 profiles described in the manuals and online help have the interleaver feature enabled for maximum protection against small interruptions on the LRE link.

The interleaver feature delays the data, while increasing protection for the data against very small interruptions in the LRE link. By enabling the low latency feature, data is more susceptible to interruptions on the LRE link, but the delay is removed. The LL in these profiles stands for low latency. In these profiles, the interleaver feature is turned off.

Table 9 lists all of the LRE profiles available on the Catalyst 2900 LRE XL switches.


Note Use the rates and distances in Table 9 as guidelines only. Factors such as the type of cable you use, how it is bundled, and the interference and noise on the LRE link can affect the actual LRE link performance. Contact Cisco Systems for information about limitations and optimization of LRE link performance.



Note The net data rates in Table 9 are slightly less than the gross data rates displayed by the show controllers lre profile names privileged EXEC command.

The "Overview" and "Installation" chapters of the Catalyst 2900 Series XL Hardware Installation Guide and the "Overview" chapter of the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide describe connecting a Cisco PS-1M-LRE-48 plain old telephone service (POTS) splitter to a private branch exchange (PBX) switch. Cisco Long-Reach Ethernet (LRE) products are designed to share lines with analog, integrated services digital network (ISDN), and digital private branch exchange (PBX) switch telephones that use the 0 to 700 kHz frequency range.


Note Digital telephones connected to digital PBX switches that use frequencies above 700 kHz will not work when sharing a line with LRE signals. Due to the proprietary nature of digital PBX switches, some digital PBX switch services use frequencies above 700 kHz. [CSCdu73260]


Use only a 19-inch rack to rack-mount a Catalyst 2900 LRE XL switch. Do not install an LRE switch in a 23- or 24-inch rack as described in the Catalyst 2900 Series XL Hardware Installation Guide.


Caution The mounting brackets shipped with a Catalyst 2900 LRE XL switch cannot support the switch in a 23- or 24-inch rack. If you install the switch in a 23- or 24-inch rack, the switch sags towards the rear of the rack.

The Cisco part numbers for the LRE cables are incorrect in the Catalyst 2900 Series XL Hardware Installation Guide. These are the correct part numbers:

CAB-5-M120M120-5= (Category 5 cable with two 120-degree, male-to-male RJ-21 connectors)

CAB-5-M180M120-5= (Category 5 cable with one 180-degree and one 120-degree male-to-male RJ-21 connector)

The circuit for pins 24 and 49 of the RJ-21 connector listed in Table B-1 of the Catalyst 2900 Series XL Hardware Installation Guide is incorrect. Table 10 lists the correct circuit.

The Catalyst 3508 XL switch (WS-C3508G-XL) now ships with a power rating of 1.5A/0.75A. The back-panel illustration of the Catalyst 3508 XL switch in the Catalyst 3500 Series XL Hardware Installation Guide shows an outdated power rating of 1A/0.5A.

Initial Switch Configuration

This section provides these procedures:

"Using the Setup Program" section

"Installing the Required Plug-In" section

"Configuring Your Browser" section

"Displaying the CMS Access Page" section

This section assumes you have already installed the switch and connected devices to it, as described in the switch hardware installation guide.

Using the Setup Program

You can use an automatic setup program to assign switch IP information, host and cluster names, and passwords and to create a default configuration for continued operation. Later, you can use CMS or the command-line interface (CLI) to customize your configuration. To run the setup program, access the switch from the PC terminal that you connected to the console port. For information about connecting a PC or terminal to the switch console port, refer to the switch hardware installation guide.


Note If the switch will be a cluster member, you do not always need to assign IP information or a password, as the switch will be managed through the IP address of the command switch. If you are configuring a command switch or standalone switch, you need to assign IP information. Refer to the switch software configuration guide for more information.


The first time that you access the switch, it runs a setup program that prompts you for IP and other configuration information necessary for the switch to communicate with local routers and the Internet. This information is also required if you plan to use CMS to configure and manage the switch.

You will need the following information from your system administrator:

Switch IP address

___________.___________.___________._________

Subnet mask (netmask)

___________.___________.___________._________

Default gateway (router)

___________.___________.___________._________

Enable secret password

___________________________________________


Use this procedure to create an initial configuration for the switch:


Note Be sure the rollover cable is connecting a PC serial port to the switch console port. The data characteristics are 9600 baud, 8 data bits, 1 stop bit, and no parity. Use the supplied rollover cable and DB-9 adapter to connect a PC to the switch console port. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, refer to the "Cable and Connector Specifications" appendix in the Catalyst 2900 Series XL Hardware Installation Guide and the Catalyst 3500 Series XL Hardware Installation Guide.


At any point you can enter a question mark for help. Use Ctrl-C to abort the configuration dialog at any prompt. The default settings are in square brackets.


Step 1 Enter Y at the first prompt.

Continue with configuration dialog? [yes/no]: y

Step 2 Enter the switch IP address, and press Return:

Enter IP address: ip_address

Step 3 Enter the subnet mask, and press Return:

Enter IP netmask: ip_netmask

Step 4 Enter Y at the next prompt to specify a default gateway (router):

Would you like to enter a default gateway address? [yes]: y 

Step 5 Enter the IP address of the default gateway, and press Return.

IP address of the default gateway: ip_address

Step 6 Enter a host name for the switch, and press Return.


Note On a command switch, the host name is limited to 28 characters; on a member switch to 31 characters. Do not use -n, where n is a number, as the last character in a host name for any switch.


Enter a host name: host_name 

Step 7 Enter a secret password, and press Return.


Note The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows spaces, but ignores leading spaces.


Enter enable secret: secret_password

Step 8 Enter Y to enter a Telnet password:

Would you like to configure a Telnet password? [yes] y

Note The password can be from 1 to 25 alphanumeric characters, is case sensitive, allows spaces, but ignores leading spaces.


Step 9 Enter the Telnet password, and press Return:

Enter Telnet password: telnet_password

Step 10 Enter Y to configure the switch as the cluster command switch. Enter N to configure it as a member switch or as a standalone switch.


Note If you enter N, the switch appears as a candidate switch in Cluster Builder. In this case, the message in Step 11 is not displayed.


Would you like to enable as a cluster command switch? y

Step 11 Assign a name to the cluster, and press Return.

Enter cluster name: cls_name

Note The cluster name can be 1 to 31 alphanumeric characters, dashes, or underscores.


Step 12 The initial configuration is displayed:

The following configuration command script was created: 
 
ip subnet-zero 
interface VLAN1 
ip address 172.20.153.36 255.255.255.0 
ip default-gateway 172.20.153.01 
hostname host_name 
enable secret 5 $1$M3pS$cXtAlkyR3/6Cn8/ 
line vty 0 15 
password telnet_password 
snmp community private rw 
snmp community public ro 
cluster enable cls_name 
 
end 

Step 13 Verify that the information is correct.

If the information is correct, enter Y at the prompt, and press Return.

If the information is not correct, enter N at the prompt, press Return, and begin again at Step 1.

Use this configuration? [yes/no]: y 


After you complete the setup program, the switch can use the created default configuration. If you want to change this configuration or want to perform other management tasks, use one of these tools:

CMS from your browser (See the "Installing the Required Plug-In" section, the"Configuring Your Browser" section, and the "Displaying the CMS Access Page" section.)

Command-line interface (CLI) (Refer to the switch software configuration guide.)

The switch software configuration guide provides more information about how to set a password to protect the switch against unauthorized Telnet access and how to access the switch if you forget the password.

Installing the Required Plug-In

A browser Java plug-in is required to access the HTML-based CMS. Download and install the plug-in before you start CMS.

If the Java applet does not initialize after you have installed the plug-in, open the Java Plug-in Control Panel (Start > Programs > Java Plug-in Control Panel), and verify that in the Proxies tab the Use browser settings is checked and that no proxies are enabled.

If you are running McAfee VirusScan on Windows 2000 and the plug-in takes a long time to load, you can speed up CMS operation by disabling the ViruScan Internet Filter option, the Download Scan option, or both:

From the Start menu, disable the options by selecting Start > Programs > Network Associates > Virus Scan Console > Configure.

or

From the taskbar, right-click the Virus Shield icon and in the Quick Enable menu, disable the options by deselecting Internet Filter or Download Scan.

Using the CLI to Upgrade a Catalyst 2900 LRE XL Switch

Using the CLI to Upgrade a Catalyst 3500 XL Switch

"Using the CLI to Upgrade Member Switches" section


Note Before upgrading your switch to Cisco IOS Release 12.0(5.4)WC(1), read the "Guidelines for Upgrading Switch Software" section for important information.



Note For CMS instructions for upgrading switch software to this release, refer to the online help.


Guidelines for Upgrading Switch Software

When upgrading switch software, follow these rules:

You cannot install the original edition software for switches with 4 MB of DRAM on Catalyst 2900 XL and Catalyst 3500 XL switches with 8 MB of DRAM.

Similarly, you cannot upgrade Catalyst 2900 XL switches with 4 MB of DRAM to an 8-MB image. The 4-MB models are WS-C2908-XL, WS-C2916M-XL, WS-C2924C-XL, and WS-C2924-XL. In addition, these switches must run IOS Release 11.2(8.x)SA6 original edition software to be cluster members. No original edition software package is available for this release of IOS. To determine the switch DRAM size, enter the show version user EXEC command.

You cannot use the web-based interface to upgrade a switch running Release 11.2(8)SA2 or earlier releases. Use the CLI to perform the upgrade.

Upgrading the LRE switch software involves installing the LRE firmware file (e2rb.bin). You cannot use the Cluster Management Suite (CMS) software to install this file. To upgrade the LRE switch software, use the CLI procedure described in the "Downloading the New Software and TFTP Server Application to Your Management Station" section.

Before downloading the .tar file, refer to the "Using the CLI to Upgrade a Catalyst 2900 LRE XL Switch" section. We recommend that you delete the existing LRE firmware file (e2rb.bin) from the switch (Step 6). After copying the new image and HTML files to the switch Flash memory (Step 16), install the new LRE firmware file (Step 17). [CSCdu27029]

The minimum software version required on the LRE switches is Cisco IOS Release 12.0(5.3)WC(1)

If your switch is running Release 11.2(8)SA3, SA4, or SA5 (Catalyst 2900 XL only), we recommend that you upgrade the switch software by using VSM. If you are upgrading a switch running Release 11.2(8)SA6 or later to this release, we recommend that you use Cluster Manager. For CMS instructions for upgrading switch software, refer to the switch software configuration guide or the online help for that release.

When using Cluster Manager, you cannot upgrade Catalyst 2900 XL and Catalyst 3500 XL switches at the same time. However, you can group together and upgrade Catalyst 1900 and Catalyst 2820 switches at the same time.

For Catalyst 2900 XL and Catalyst 3500 XL switches, enter the image_name.tar filename in the New File Name field. The .tar file contains both the IOS image and the web-management code.

For Catalyst 1900 and Catalyst 2820 switches, enter the image_name.bin filename in the New File Name field. The .bin file contains the software image and the web-management code.

Upgrade Catalyst 1900 and Catalyst 2820 switches last. To function efficiently, these switches need to be rebooted shortly after the upgrade occurs. If you do not click Reboot Cluster in 30 seconds after the upgrade, the Catalyst 1900 and Catalyst 2820 switches automatically reboot.

When using Cluster Manager to upgrade multiple switches from the Cisco TFTP server, the Cisco TFTP server application can handle multiple requests and sessions. When using Cluster Manager to upgrade multiple switches from the Cisco TFTP server, you must first disable the TFTP Show File Transfer Progress and the Enable Logging options to avoid TFTP server failures. If you are performing multiple-switch upgrades with a different TFTP server, it must be capable of managing multiple requests and sessions at the same time.

Overview of the Switch Upgrade Process

See the following sections if you are using CMS or the CLI to upgrade the software on your switch or switch cluster:

If you are using VSM to upgrade a specific switch, follow the steps in the "Using VSM to Upgrade a Specific Switch" section.

If you are using Cluster Manager to upgrade a switch or switch cluster running Release 11.2(8)SA6 or later, follow the steps in the "Using Cluster Manager to Upgrade One or More Switches" section.

If you are using the CLI to upgrade a switch, follow the steps in one of these sections:

"Using the CLI to Upgrade an 8-MB Catalyst 2900 XL Switch" section

"Using the CLI to Upgrade a Catalyst 2900 LRE XL Switch" section

"Using the CLI to Upgrade a Catalyst 3500 XL Switch" section

"Using the CLI to Upgrade Member Switches" section

When you upgrade a switch, the switch continues to operate while the new software is copied to Flash memory. Features provided by the new software are not available until you reboot the switch.

If there is enough space on the switch Flash memory, the new image is copied to the switch but does not replace the existing image until you reboot the switch. If a failure occurs while you are copying the new image to the switch, you can use the existing image to reboot the switch.

If there is not enough space for two images on the switch Flash memory, the new image is copied over the existing one. If a failure occurs while you are copying the new image to the switch, or if the new startup configuration fails, you must use the XMODEM Protocol to reinstall a previous or new image to the switch Flash memory. For more information, refer to the "Recovering from Corrupted Software" section in the "Troubleshooting" chapter of the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.

Which Software Files to Download from Cisco.com

New software releases are posted on Cisco.com and are also available through authorized resellers. From Cisco.com, you can also download a TFTP server application to copy the switch software from your PC to the switch.

Table 11 describes the file extensions and what they mean for the upgrade procedure. Table 12 and Table 13 list the software files you need from Cisco.com.


Note We recommend that you download the combined .tar file that contains the image file and the HTML files. The procedures in this document are for upgrading a switch by using the combined .tar file.


Table 11 Possible Extensions for IOS Software Files

Extension
Description

.tar

A compacted file from which you can extract files by using the tar command. There are two types of .tar files:

A combined .tar file that contains both the IOS image file and the HTML files.

An HTML .tar file that has the letters HTML in its name and contains just the HTML files for the IOS release. From the CLI, you can upgrade the switch software by using this HTML file and the IOS image file.

.bin

The IOS image file and the LRE firmware file that you can copy to the switch through TFTP.

Downloading the New Software and TFTP Server Application to Your Management Station

Follow these steps to download the new software and, if necessary, the TFTP server application, from Cisco.com to your management station:


Step 1 Use Table 12 and Table 13 to identify the files that you want to download.

Step 2 Download the files from one of the following locations:

If you have a SmartNet support contract, go to one of these URLs, and download the appropriate files:

http://www.cisco.com/pcgi-bin/tablebuild.pl/cat2900XL
http://www.cisco.com/pcgi-bin/tablebuild.pl/cat3500XL

If you do not have a SmartNet contract, go to one of these URLs, and download the appropriate files:

http://www.cisco.com/pcgi-bin/tablebuild.pl/cat2900XL
http://www.cisco.com/pcgi-bin/tablebuild.pl/cat3500XL

Step 3 Use the CLI or web-based interface to perform a TFTP transfer of the file or files to the switch after you have downloaded the correct files to your PC or workstation.

The readme.txt file describes how to download the TFTP server application. New features provided by the software are not available until you reload the software.


Copying the Current Startup Configuration from the Switch to a PC or Server

When you make changes to a switch configuration, your changes become part of the running configuration. When you enter the command to save those changes to the startup configuration, the switch copies the configuration to the config.text file in Flash memory. To ensure that you can recreate the configuration if a switch fails, you might want to copy the config.text file from the switch to a PC or server.

The following procedure requires a configured TFTP server such as the Cisco TFTP server available on Cisco.com.

Beginning in privileged EXEC mode, follow these steps to copy a switch configuration file to the PC or server that has the TFTP server application:


Step 1 Copy the file in Flash memory to the root directory of the TFTP server:

switch# copy flash:config.text tftp

Step 2 Enter the IP address of the device where the TFTP server resides:

Address or name of remote host []? ip_address

Step 3 Enter the name of the destination file (for example, config.text):

Destination filename [config.text]? yes/no

Step 4 Verify the copy by displaying the contents of the root directory on the PC or server.


Using VSM to Upgrade a Specific Switch


Note If you use VSM to upgrade your Catalyst 2900 XL switch from a release before Release 11.2(8)SA6 to this release, you must first perform Steps 1 through 4 to rename the image file to ensure that you can reload the software. You do not need to perform Steps 1 through 4 if you are using VSM to upgrade a Catalyst 2900 XL or Catalyst 3500 XL switch from Release 11.2(8)SA6 or later. You can rename the image file by accessing the CLI through Telnet or by connecting to the switch console port.



Note You cannot use CMS to upgrade an LRE switch. To upgrade an LRE switch, refer to the "Using the CLI to Upgrade a Catalyst 2900 LRE XL Switch" section.



Note If the software upgrade from VSM is incomplete, see the "Recovering from an Incomplete VSM Software Upgrade" section.



Tips If your switch is not configured for Telnet, follow the procedure described in the "Telnet Access to the CLI" section in the "General Switch Administration" chapter of the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.


Follow these steps to rename the image file by using the CLI, and then use VSM to upgrade the software:


Step 1 Access the CLI by starting a Telnet session or by connecting to the switch console port through the RS-232 connector.

To start a Telnet session on your PC or workstation, enter this command:

server% telnet switch_ip_address

Step 2 Enter the Telnet password if you are prompted to do so.

Step 3 Enter privileged EXEC mode:

switch> enable 
switch#

Step 4 Enter the switch password if you are prompted to do so.

Step 5 Display the files in Flash memory:

switch# dir flash:
Directory of flash:/

  2  -rwx        4484   Mar 05 1993 00:31:09  vlan.dat
  3 -rwx         110   Mar 01 1993 19:50:50  info
 92  -rwx         877   Mar 06 1993 18:39:38  placement.txt
 5  -rwx     1644050   Mar 01 1993 19:36:14  c2900XL-c3h2s-mz-112.8.SA5.bin
  6  drwx        6720   Mar 01 1993 00:18:36  html
 86  -rwx         110   Mar 01 1993 19:37:00  info.ver
116  -rwx        3686   Mar 01 1993 19:55:33  config.text
 89  -rwx          25   Mar 01 1993 00:26:30  snmpengineid
  7  -rwx         313   Mar 01 1993 19:34:57  env_vars

Step 6 Rename the image file to boot.bin:

switch# rename flash:c2900XL-c3h2s-mz-112.8.SA5.bin flash:boot.bin

Ensure that there are no other image files in Flash memory.

Step 7 Start VSM and display the System Configuration window by selecting System > System Configuration.

Step 8 In the Cisco IOS Image File field, enter boot.bin.

Step 9 Check the Retain Current IOS Image File Name check box.

Step 10 Complete the other fields on the window as described in the online help.

Step 11 Click Upgrade IOS Software and Visual Switch Manager.

Step 12 Display the contents of Flash memory, and verify that the boot.bin file was downloaded:

switch# dir flash:
Directory of flash:/

  2  -rwx        4484   Mar 05 1993 00:31:09  vlan.dat
  4  -rwx         110   Mar 01 1993 19:50:50  info
 92  -rwx         877   Mar 06 1993 18:39:38  placement.txt
  5  -rwx     1644050   Mar 01 1993 19:36:14  boot.bin
  6  drwx        6720   Mar 01 1993 00:18:36  html
 86  -rwx         110   Mar 01 1993 19:37:00  info.ver
116  -rwx        3686   Mar 01 1993 19:55:33  config.text
 89  -rwx          25   Mar 01 1993 00:26:30  snmpengineid
  7  -rwx         313   Mar 01 1993 19:34:57  env_vars

3612672 bytes total (840704 bytes free)

Step 13 Verify that the switch reloads correctly by displaying the boot variable (BOOT path-list), boot.bin.

switch# show boot
BOOT path-list:      flash:boot.bin
Config file:         flash:config.text
Enable Break:        no
Manual Boot:         no
HELPER path-list:    
NVRAM/Config file
      buffer size:   32768

Recovering from an Incomplete VSM Software Upgrade

If you do not follow the preceeding procedure, an upgrade can fail due to insufficient space because of multiple software images or other files in Flash memory. When the upgrade fails, the image file is copied to Flash memory, but there is insufficient space for the HTML files, and you lose access to VSM.

If a failure occurs, ensure that the image file in Flash memory has the same name as the contents of the boot variable. You can compare these two names by following Steps 12 and 13 in the procedure.

If the contents of the boot variable and the image file name are the same, the switch can reset successfully. If they are different, rename the image file, or reset the boot variable by entering the system boot name global configuration command. The boot variable and the image file name should be the same.

To recover from the incomplete download of the HTML files, log in to the switch, and upgrade the software as described in the "Using the CLI to Upgrade Member Switches" section.

Using Cluster Manager to Upgrade One or More Switches

You can use the Software Upgrade feature of the Cluster Manager to upgrade all or some of the switches in a cluster at once. Consider the following conditions when doing an upgrade:

You cannot upgrade Catalyst 2900 XL and Catalyst 3500 XL switches at the same time. However, you can group together and upgrade Catalyst 1900 and Catalyst 2820 switches at the same time.

Upgrade Catalyst 1900 and Catalyst 2820 switches last. To function efficiently, these switches need to be rebooted shortly after the upgrade occurs. If you do not click Reboot Cluster in 30 seconds after the upgrade, the Catalyst 1900 and Catalyst 2820 switches automatically reboot.

For Catalyst 2900 XL and Catalyst 3500 XL switches, enter the image_name.tar filename in the New File Name field. The .tar file contains both the IOS image and the web-management code.

For Catalyst 1900 and Catalyst 2820 switches, enter the image_name.bin filename in the New File Name field. The .bin file contains the software image and the web-management code.


Note You cannot use CMS to upgrade an LRE switch.


Follow these steps to use Cluster Manager to upgrade software. Refer to the online help for more details.


Step 1 In Cluster Manager, select System > Software Upgrade to display the Software Upgrade window.

Step 2 Enter the .tar filename (for Catalyst 2900 XL and Catalyst 3500 XL switches) or the .bin filename (for Catalyst 1900 and Catalyst 2820 switches) that contains the switch software image and the web-management code.

You can enter just the filename or a pathname into the New Image File Name field. You do not need to enter a pathname if the image file is in the directory that you have defined as the TFTP root directory.



Note You can also use Visual Switch Manager (VSM) to upgrade a single switch by following the same software upgrade procedure.



Note Close your browser after the upgrade process is complete.


On Catalyst 2900 XL and Catalyst 3500 XL switches, new images are copied to Flash memory and do not affect operation. The switch checks Flash memory to ensure that there is sufficient space before the upgrade takes place. If there is enough space, the new image is copied to the switch without replacing the old image, and after the new image is completely downloaded, the old one is erased. In this case, you can still reboot your switch by using the old image if a failure occurs during the copy process.

If there is not enough space in Flash memory for the new and old images, the old image is deleted, and the new image is downloaded.

On Catalyst 1900 and Catalyst 2820 switches, the new image overwrites the current image during the upgrade.


Note If a failure occurs while copying a new image to the switch, and the old image has already been deleted, you need to use the XMODEM protocol to recover an image for the switch. For more information, refer to the "Recovering from Corrupted Software" section in the "Troubleshooting" chapter of the Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide.


Using the CLI to Upgrade an 8-MB Catalyst 2900 XL Switch


Caution The 4-MB Catalyst 2900 XL switches do not have sufficient memory to be upgraded to this release. You cannot upgrade the switches to an 8-MB image. The 4-MB models are WS-C2908-XL, WS-C2916M-XL, WS-C2924C-XL, and WS-C2924-XL. These switches must run Release 11.2(8.x)SA6 original edition software to be cluster members.


Note If you are upgrading a Catalyst 2900 LRE XL switch, see the "Using the CLI to Upgrade a Catalyst 2900 LRE XL Switch" section.


This procedure is for upgrading Catalyst 2900 XL switches with 8 MB of DRAM. You upgrade a switch by extracting the IOS image file and the HTML files from a combined .tar file. You copy the files to the switch from a TFTP server and extract the files by entering the tar command. The procedure returns these results:

Changes the name of the current image file to the name of the new file that you are copying and replacing the old image file with the new one by using the tar command.

Disables access to the HTML pages and deleting the existing HTML files before you upgrade the software to avoid a conflict with users accessing the web pages during the software upgrade.

Reenables access to the HTML pages after the upgrade is complete.


Note If you want to separately copy the IOS image or HTML files to the switch, refer to the Catalyst 2900 Series XL Release Notes for Release 11.2(8)SA4 on Cisco.com.


If you are unsure whether your switch has 4 MB or 8 MB of memory, you can verify memory capacity at Step 4.

Follow these steps to upgrade the switch software by using the tar command to start a TFTP transfer:


Step 1 If your PC or workstation cannot act as a TFTP server, copy the file to a TFTP server to which you have access.

Step 2 Access the CLI by starting a Telnet session or by connecting to the switch console port through the RS-232 connector.

To start a Telnet session on your PC or workstation, enter the following command:

server% telnet switch_ip_address

Enter the Telnet password if you are prompted to do so.

Step 3 Enter privileged EXEC mode:

switch> enable 
switch#

Enter a password if you are prompted to do so.

Step 4 Confirm that you have an 8-MB switch:

3612672 bytes total (940032 bytes free) 

Step 6 Using the exact, case-sensitive name of the combined .tar file that you downloaded, rename the running image file to that name, and replace the .tar extension with a .bin extension. The image file name is then the same as the downloaded file name but with a .bin extension. This step does not affect the operation of the switch.

switch# rename flash:current_image flash:new_image 
Source filename [current_image]?  
Destination filename [new_image]? 

For example:

switch# rename flash:c2900XL-h2-mz-112.8.2-SA6.bin 
flash:c2900XL--c3h2s-mz-120-5.3.WC.1.bin 
Source filename [c2900XL-h2-mz-112.8.2-SA6.bin]? 
Destination filename [c2900XL-c3h2s-mz-120-5.3.WC.1.bin]? 

Step 7 Enter global configuration mode:

switch# config terminal 
Enter configuration commands, one per line. End with CNTL/Z. 

Step 8 Disable access to the switch HTML pages:

switch(config)# no IP http server

Step 9 If you entered the boot command with the name of the image file, enter this command to change it to the new name.

switch(config)# boot system flash:new_image

For example:

switch(config)# boot system flash:c2900XL-c3h2s-mz-120-5.3.WC.1.bin

Note If the show boot command entered in Step 5 displays no image name, you do not need to enter this command; the switch automatically finds the correct file to use when it resets


Step 10 Return to privileged EXEC mode:

switch(config)# end

Step 11 Remove the HTML files:

switch# delete flash:html/* 

Step 12 Press Enter to confirm the deletion of each file. Do not press any other keys during this process.

Step 13 If upgrading from Release 11.2(8)SA5 or earlier, remove the files in the Snmp directory:

switch# delete flash:html/Snmp/*

Make sure the S in Snmp is uppercase.

Press Enter to confirm the deletion of each file. Do not press any other keys during this process.


Caution In the following step, the tar command copies the combined .tar file that contains both the image and the HTML files. You do not need to copy an HTML.tar file in this procedure.

Step 14 Enter the following command to copy the new image and HTML files to the switch Flash memory:

switch# tar /x tftp://server_ip_address//path/filename.tar flash: 
Loading /path/filename.tar from server_ip_address (via VLAN1):!) 
extracting info (111 bytes)
extracting c2900XL-c3h2s-mz-120-5.3.WC.1.bin (1557286 bytes)!!!!!!!!!!!!!!!!!!!!
html/ (directory)
extracting html/Detective.html.gz (1139 bytes)!
extracting html/ieGraph.html.gz (553 bytes)
extracting html/DrawGraph.html.gz (787 bytes)!
. . . 

Depending on the TFTP server being used, you might need to enter only one slash (/) after the server_ip_address in the tar command.

Step 15 Enter global configuration mode:

switch# configure terminal 
Enter configuration commands, one per line. End with CNTL/Z. 

Step 16 Re-enable access to the switch HTTP pages:

switch(config)# IP http server

Step 17 Return to privileged EXEC mode:

switch(config)# end

Step 18 Reload the new software with the following command:

switch# reload 
System configuration has been modified. Save? [yes/no]:y 
Proceed with reload? [confirm] 

Step 19 Press Return to confirm the reload.

Your Telnet session ends when the switch resets.

Step 20 After the switch reboots, use Telnet to return to the switch, and enter the privileged EXEC show version command to verify the upgrade procedure. If you have a previously opened browser session to the upgraded switch, close the browser, and start it again to ensure that you are using the latest HTML files.


Using the CLI to Upgrade a Catalyst 2900 LRE XL Switch


Note If you are upgrading a Catalyst 2900 XL switch, which is not an LRE switch, see the "Using the CLI to Upgrade an 8-MB Catalyst 2900 XL Switch" section.


Follow these steps to upgrade the LRE switch software:


Step 1 If your PC or workstation cannot act as a TFTP server, copy the file to a TFTP server to which you have access.

Step 2 Access the CLI by starting a Telnet session or by connecting to the switch console port through the RS-232 connector.

To start a Telnet session on your PC or workstation, enter this command:

server% telnet switch_ip_address

Enter the Telnet password if you are prompted to do so.

Step 3 Enter privileged EXEC mode:

switch> enable
switch#

Enter a password if you are prompted to do so.

Step 4 Display the name of the running (default) image file (BOOT path-list). The following example shows the name in italic:

switch# show boot
BOOT path-list:    flash:current_image
Config file:       flash:config.text
Enable Break:      1
Manual Boot:       no
HELPER path-list: 
NVRAM/Config file
buffer size: 32768

If there is no file defined in the BOOT path-list, enter dir flash: to display the contents of Flash memory. The file named c2900XL-c3h2-mz-120-5.1.WC.1.bin is your previous image file.

switch# dir flash:

7741440 bytes total (4692992 bytes free)

Step 5 Using the exact, case-sensitive name of the combined .tar file that you downloaded, rename the running image file to that name, and replace the .tar extension with a .bin extension. The image file name is then the same as the downloaded file name but with a .bin extension. This step does not affect the operation of the switch.

switch# rename flash:c2900XL-c3h2s-mz.120-5.1.WC.1.bin 
flash:c2900XL-c3h2s-mz.120-5.3.WC.1.bin
Destination filename [c2900XL-c3h2s-mz.120-5.3.WC.1.bin]? 

Step 6 Delete the e2rb.bin file:

switch# delete flash:e2rb.bin

Step 7 Press Enter to confirm deletion of the e2rb.bin file.

Step 8 Enter global configuration mode:

switch# config terminal

Step 9 Disable access to the switch HTML pages:

switch(config)# no IP http server

Step 10 If you entered the boot command with the name of the image file, enter this command to change it to the new name:


Note You do not need to perform this step if the show boot command entered in Step 4 displays no image name; the switch automatically finds the correct file to use when it resets.


switch(config)# boot system flash:new_image

For example:

switch(config)# boot system flash:c2900XL-c3h2s-mz-120-5.3.WC.1.bin

Step 11 Return to privileged EXEC mode:

switch(config)# end

Step 12 Remove the HTML files:

switch# delete flash:html/*

Step 13 Press Enter to confirm the deletion of each file. Do not press any other keys during this process.

Step 14 If upgrading from Release 11.2(8)SA5 or earlier, remove the files in the Snmp directory:

switch# delete flash:html/Snmp/*

Note Make sure the S in Snmp is uppercase.


Step 15 Press Enter to confirm the deletion of each file. Do not press any other keys during this process.

Step 16 Enter the following command to copy the new image and HTML files to the switch Flash memory:


Caution In this step, the tar command copies the combined .tar file that contains both the image and the HTML files. You do not need to copy an HTML.tar file in this procedure.

switch# tar /x tftp://server_ip_address/path/filename.tar flash:    
Loading /path/filename.tar from server_ip_address (via VLAN1): !
extracting info (111 bytes)
extracting c2900XL-c3h2s-mz.120-5.3.WC.1.bin (1750311 
bytes)!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

html/ (directory)
extracting html/ClusterBuilder.html.gz (670 bytes)
extracting html/ClusterManager.html.gz (624 bytes)
extracting html/back.html.gz (211 bytes)!
. . .

Depending on the TFTP server being used, you might need to enter only one slash (/) after the server_ip_address in the tar command. The tar command extracts the IOS image and the HTML files from the combined .tar file during the TFTP copy to the switch.

Step 17 Copy the e2rb.bin file to the switch Flash memory:

switch# copy tftp://server_ip_address/path/e2rb.bin flash:
Destination filename [e2rb.bin]? 
Accessing tftp://server_ip_address/path/e2rb.bin...
Loading /path/e2rb.bin from server_ip_address (via VLAN1): !!
[OK - 8192 bytes]

8192 bytes copied in 0.259 secs

Step 18 Enter global configuration mode:

switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.

Step 19 Re-enable access to the switch HTTP pages:

switch(config)# IP http server

Step 20 Return to privileged EXEC mode:

switch(config)# end

Step 21 Reload the new software with the following command:

switch# reload
System configuration has been modified. Save? [yes/no]: y
Proceed with reload? [confirm]

Step 22 Press Return to confirm the reload.

Your Telnet session ends when the switch resets.

Step 23 After the switch reboots, use Telnet to return to the switch, and enter the privileged EXEC show version command to verify the upgrade procedure.

If you have a previously opened browser session to the upgraded switch, close the browser, and start it again to ensure that you are using the latest HTML files.


Using the CLI to Upgrade a Catalyst 3500 XL Switch

This procedure is for upgrading Catalyst 3500 XL switches by copying the combined .tar file to the switch. You copy the files to the switch from a TFTP server and extract the files by entering the tar command, with the following results:

Changes the name of the current image file to the name of the new file that you are copying and replaces the old image file with the new one.

Disables access to the HTML pages and deletes the existing HTML files before the software upgrade to avoid a conflict if users access the web pages during the software upgrade.

Reenables access to the HTML pages after the upgrade is complete.

Follow these steps to upgrade the switch software by using a TFTP transfer:


Step 1 If your PC or workstation cannot act as a TFTP server, copy the file to a TFTP server to which you have access.

Step 2 Access the CLI by starting a Telnet session or by connecting to the switch console port through the RS-232 connector.

To start a Telnet session on your PC or workstation, enter the following command:

server% telnet switch_ip_address

Enter the Telnet password if you are prompted to do so.

Step 3 Enter privileged EXEC mode:

switch> enable 
switch#

Enter the password if you are prompted to do so.

Step 4 Display the name of the running (default) image file (BOOT path-list). The following example shows the name in italic:

switch# show boot 
BOOT path-list:    flash:current_image 
Config file:       flash:config.text 
Enable Break:      1 
Manual Boot:       no 
HELPER path-list:  
NVRAM/Config file 
buffer size: 32768

Step 5 If there is no software image defined in the BOOT path-list, enter dir flash: to display the contents of Flash memory.

Step 6 Using the exact, case-sensitive name of the combined .tar file that you downloaded, rename the running image file to that name, and replace the .tar extension with .bin. The image filename is then the same as the downloaded filename but with a .bin extension. This step does not affect the operation of the switch.

switch# rename flash:current_image flash:new_image 
Source filename [current_image]?  
Destination filename [new_image]? 

For example:

switch# rename flash:c3500XL-c3h2-mz-112.8.2-SA6.bin 
flash:c3500XL-c3h2s-mz-120-5.3.WC.1.bin 

Step 7 Display the contents of Flash memory to verify the renaming of the file:

switch# dir flash: 
Directory of flash:/

 2  ---x     1644045   Apr 04 1993 15:17:15  c3500XL-c3h2s-mz-120-5.3.WC.1.bin

115  -rwx         354   Mar 13 1993 04:17:15  env_vars

3612672 bytes total (936960 bytes free) 

Step 8 Enter global configuration mode:

switch# config terminal 
Enter configuration commands, one per line. End with CNTL/Z. 

Step 9 Disable access to the switch HTML pages:

switch(config)# no IP http server

Step 10 Enter the boot command with the name of the new image filename:

switch(config)# boot system flash:new_image

For example:

switch(config)# boot system flash:c3500XL-c3h2s-mz-120-5.3.WC.1.bin

Note If the show boot command entered in Step 4 displays no image name, you do not need to enter this command; the switch automatically finds the correct file to use when it resets.


Step 11 Return to privileged EXEC mode:

switch(config)# end

Step 12 Remove the HTML files:

switch# delete flash:html/* 

Press Enter to confirm the deletion of each file. Do not press any other keys during this process.


Caution In the following step, the tar command copies the combined .tar file that contains both the image and the HTML files. You do not need to copy an HTML .tar file in this procedure.

Step 13 Enter the following command to copy the new image and HTML files to Flash memory:

switch# tar /x tftp://server_ip_address//path/filename.tar flash: 
Loading /path/filename.tar from server_ip_address (via VLAN1):!) 
extracting info (110 bytes)
extracting c3500XL-c3h2s-mz-120-5.3.WC.1.bin (1271095 bytes)!!!!!!!!!!!!!!!!!!!!
html/ (directory)
extracting html/Detective.html.gz (1139 bytes)!
extracting html/ieGraph.html.gz (553 bytes)
extracting html/DrawGraph.html.gz (787 bytes)
extracting html/GraphFrame.html.gz (802 bytes)!
... 

Depending on the TFTP server being used, you might need to enter only one slash (/) after the server_ip_address in the tar command.

Step 14 Enter global configuration mode:

switch# config terminal 
Enter configuration commands, one per line. End with CNTL/Z. 

Step 15 Re-enable access to the switch HTTP pages:

switch(config)# IP http server

Step 16 Return to privileged EXEC mode:

switch(config)# end

Step 17 Reload the new software with the following command:

switch# reload 
System configuration has been modified. Save? [yes/no]:y 
Proceed with reload? [confirm] 

Step 18 Press Return to confirm the reload.

Your Telnet session ends when the switch resets.

Step 19 After the switch reboots, use Telnet to return to the switch, and enter the privileged EXEC mode show version command to verify the upgrade procedure. If you have a previously-opened browser session to the upgraded switch, close the browser, and start it again to ensure that you are using the latest HTML files.


Using the CLI to Upgrade Member Switches

Because a member switch might not be assigned an IP address, command-line software upgrades through TFTP are managed through the command switch.

This section provides these procedures:

"Upgrading Catalyst 2900 XL or Catalyst 3500 XL Member Switches" section

"Upgrading Catalyst 1900 or Catalyst 2820 Member Switches" section

Upgrading Catalyst 2900 XL or Catalyst 3500 XL Member Switches

Follow these steps to upgrade the software on a Catalyst 2900 XL or Catalyst 3500 XL member switch:


Step 1 In privileged EXEC mode on the command switch, display information about the cluster members:

switch# show cluster members

From the display, select the number of the member switch that you want to upgrade. The member number is in the SN column of the display. You need this member number for Step 2.

Step 2 Log in to the member switch (for example, member number 1):

switch# rcommand 1

Step 3 Start the TFTP copy function as if you were initiating it from the command switch.

switch-1# tar /x tftp://server_ip_address//path/filename.tar flash:
Source IP address or hostname [server_ip_address]?  
Source filename [path/filename]?  
Destination filename [flash:new_image]?  
Loading /path/filename.bin from server_ip_address (via!) 
[OK - 843975 bytes]

Step 4 Reload the new software with the following command:

switch-1# reload 
System configuration has been modified. Save? [yes/no]:y 
Proceed with reload? [confirm]

Press Enter to start the download.


You lose contact with the switch while it reloads the software. For more information on the rcommand command, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Command Reference.

Upgrading Catalyst 1900 or Catalyst 2820 Member Switches

Follow these steps to upgrade the software on a Catalyst 1900 or Catalyst 2820 member switch:


Step 1 In privileged EXEC mode on the command switch, display information about the cluster members:

switch# show cluster members

From the display, select the number of the member switch that you want to upgrade. The member number is in the SN column of the display. You need this member number for Step 2.

Step 2 Log in to the member switch (for example, member number 1):

switch# rcommand 1

Step 3 For switches running standard edition software, enter the password (if prompted), access the Firmware Configuration menu from the menu console, and perform the upgrade. Follow the instructions in the installation and configuration guide that shipped with your switch. When the download is complete, the switch resets and begins using the new software.

The Telnet session accesses the menu console (the menu-driven interface) if the command switch password is privilege level 15. If the command switch password is privilege level 1, you are prompted for the password.

You lose contact with the switch while it reloads the software.

Step 4 For switches running Enterprise Edition Software, start the TFTP copy as if you were initiating it from the member switch:

switch-1# copy tftp://host/src_file opcode

For example, copy tftp://spaniel/op.bin opcode downloads new system operational code op.bin from the host spaniel.

You should see the TFTP successfully downloaded operational code message. When the download is complete, the switch resets and begins using the new software.

You can also upgrade the switch software through the Firmware Configuration menu from the menu console. For more information, refer to the installation and configuration guide that shipped with your switch.

You lose contact with the switch while it reloads the software.
