The examples in this section show ways in which you might deploy XL switches in your network. The links to the BaseTX servers and workstations can be full duplex. A repeater does not support full-duplex transmission, so the links to the BaseTX repeaters are always half duplex. In this topology, the switch is in the middle of the network and can provide connectivity to a mixture of hubs, switches, and servers.
Figure shows four XL switches in a star topology. April Download this chapter. Table Features List Feature. Table Expansion Modules Module Type. STAT The port status. This is the default mode. UTL The current bandwidth in use by the switch. FDUP The port duplex mode: full duplex or half duplex. System is receiving power but is not functioning properly. The port duplex mode: full duplex or half duplex. Activity; port is transmitting or receiving data.
The LEDs display backplane utilization on a logarithmic scale. Step 10 Press Enter to confirm the deletion of each file. Do not press any other keys during this process. Note Make sure the S in Snmp is uppercase. Step 12 Press Enter to confirm the deletion of each file. Step 13 Enter the following command to copy the new image and HTML files to the switch flash memory:. Step 14 Enter global configuration mode:.
Step 17 Reload the new software with this command:. Step 18 Press Return to confirm the reload. Step 19 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 restart it to ensure that you are using the latest HTML files. Note There are no LRE firmware upgrade patch files available with this release.
LRE upgrade configurations should rarely be required. If you wish to override the switch automatic selection of LRE binaries, you have two methods available:. You can use config global commands to specify the LRE binary or binaries for a specified target type. A target type is the family [and optionally the model or model revision] of a device containing one or more upgradable hardware elements.
You can perform global LRE upgrade configurations by entering LRE upgrade controller configuration commands from the controller configuration submode. Use the upgrade configuration command in the controller submode to override the system default selection of an LRE binary to be applied on a particular remote CPE device or local LRE controller.
Controller configurations take precedence over global upgrade configurations. The preserve keyword causes the LRE upgrade mechanism to not upgrade the local controller on which preserve is configured or any of the CPE devices connected to that controller. If you want to preserve in other words, not upgrade some of the CPE devices connected to a particular controller but allow upgrades to others, you can enter controller upgrade configuration commands for the links that you want to upgrade.
The no form of the upgrade command removes the command for applying a particular LRE binary. To resume default upgrade behavior for a given controller, configure the no upgrade commands on that controller. Note You also need to remove global configurations that might also affect the controller and devices connected to it. Note When a config global command and a config controller command conflict, the config controller command has precedence.
By default, a system-wide upgrade applies the most recent versions of LRE binaries that are most compatible with each upgradable hardware module. The system-wide upgrade method is the one that you use in almost all situations. If no local or remote option is given, a system-wide upgrade is performed. Beginning in privileged EXEC mode, follow these steps to perform a system-wide upgrade to configure the LRE binary to apply to a target device and upgradable hardware element combination:.
Note The lre upgrade default mode command essentially overrides the system default selection of an LRE binary for a specified family of CPE devices target device. Enter the LRE binary to be applied, or set preserve, which prevents the upgrade of any CPE devices connected to a controller or local chipset. You can use the upgrade configuration command in the controller submode to override the system default selection of an LRE binary that will be applied on either end of a particular LRE link.
If you want to preserve in other words, not upgrade some of the CPE devices connected to a particular controller but allow upgrades to others, you can enter controller upgrade configuration commands for the links you want to upgrade.
The no form of the command removes the command for applying a particular LRE binary. To resume default upgrade behavior for a given controller, do not configure the custom upgrade commands on that controller. If you answer yes or press the Enter key, the upgrade starts. If you answer no , you get the EXEC prompt. Ethernet connectivity is temporarily lost at this point. The increased reliability is required for a successful LRE binary transfer.
The LRE link stays at a slower speed for the duration of the upgrade. Ethernet connectivity is available. Ethernet connectivity is again disrupted until the CPE device comes out of reset.
The CPE device is reset and the link is down. Ethernet connectivity is unavailable at this point. The CPE device comes out of reset. Ethernet connectivity is available but at low speeds. Upgrade data transfer begins. If you are unsure whether your switch has 4 MB or 8 MB of memory, you can verify memory capacity at Step 4.
Step 4 Confirm that you have an 8-MB switch:. For example, the file named cXL-c3h2-mz Step 6 Enter global configuration mode:. Step 8 If you entered the boot global configuration command with the name of the image file, enter this command to change the image filename to the new name.
Note If the show boot privileged EXEC command that you 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 11 Press Enter to confirm the deletion of each file. Press Enter to confirm the deletion of each file. Step 19 After the switch reboots, use Telnet to return to the switch, and enter the show version privileged EXEC command to verify the upgrade procedure. This procedure is for upgrading Catalyst XL switches by copying the combined tar file to the switch. 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. Step 7 Display the contents of flash memory to verify the renaming of the file:. Step 8 Enter global configuration mode:. Step 10 Enter the boot global configuration command with the name of the new image filename:.
Note If the show boot privileged EXEC command 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 1 In privileged EXEC mode on the command switch, display information about the 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 :. Step 4 Reload the new software with the following command:. You lose contact with the switch while it reloads the software. For more information on the rcommand privileged EXEC command, refer to the switch command reference.
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.
When you issue an snmpwalk dot1dTpFdbPort all interfaces are returned. However, the snmpwalk dot1dBasePortIfIndex displays the physical interfaces only. 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. However, the other switch might continue sending data through the FEC port. Data transmission continues normally if the LRE link is restored. Regardless of the switch model, only 64 spanning-tree instances are supported.
There is no workaround. The workaround is to enter the clear mac-address-table secure interface interface-id privileged EXEC command on the secure port. This is an Intel product defect. Instead, the switch uses 14 seconds per server no matter what is configured.
Then, the configured timeouts and retries take effect. Note If you already have the logging source-interface interface configuration command configured on your switch and you upgrade to Cisco IOS Release However, this might merely mean that the RPS is in standby mode.
Refer to the "Avoiding Configuration Conflicts" section in the "Troubleshooting" chapter of the switch software configuration guide for a table that defines these conflicts. Write down the domain name. Write down the configuration revision number.
Continue with the next steps to reset the configuration revision number on the switch. Change the domain name from the original one displayed in Step 1 to a new name. The VLAN information on the switch is updated and the configuration revision number is reset to 0. You return to privileged EXEC mode. Optional Verify that the domain name is the same as in Step 1 and that the configuration revision number is 0.
After resetting the configuration revision number, add the switch to the VTP domain. For more information about using vtp transparent mode, refer to the switch software configuration guide. You can avoid this instability in the interface by not using commas in host names or DNS names. 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. The workaround is to use a supported version of Netscape Navigator. The workaround is to use Microsoft Internet Explorer. The workaround, if you do not want to disable the proxy server settings on the browser, is to download a browser from a different vendor and use it without the proxy server settings configured to access the CMS.
Note Not all environments support the LRE profile. This file is deleted and then replaced with the most current version when you upgrade the LRE switch software. Do not delete this file after upgrading your LRE switch. Note If you accidentally delete the e2rb. For more information about these commands, refer to the switch command reference. To limit rates, use the port multicast storm control feature instead of the MVR threshold feature.
Note The LRE firmware file resides in the lre-bin directory on the switch. We strongly recommend that you do not delete this directory. The lre-bin directory can be obtained from the IOS tar file. If you delete the lre-bin directory, extract the IOS from the tar file, and copy the lre-bin directory to flash memory.
Under certain conditions, Catalyst XL and XL switches might drop from packets that are being sent to the switch management interface. Note Do not delete the system image that the router already uses.
If you are not sure which files can be safely deleted, either consult your network administrator or upgrade your compact flash memory card to a size that can accommodate both the existing files and the new system image. Optional Copy a file to a server before deleting the file from flash memory. Step 8 Optional Repeat Step 7 for each file that you identified in Step 6.
Use this command to delete a file in flash memory:. Step 10 Repeat Step 9 for each file that you identified in Step 6. Step 11 dir flash0 :. Step 12 From the displayed output of the dir flash0: command, compare the number of bytes available to the size of the system image to which you want to upgrade. This section describes how to copy the system image into the compact flash memory card for your router. Choose one of the following methods:.
This is the recommended and most common method of upgrading the system image. The following details the logistics of upgrading the system image. Tip For more detailed information on how to perform the prerequisites, see the Software Installation and Upgrade Procedure tech note. When prompted, enter the filename of the Cisco IOS software image to be installed.
When prompted, enter the filename as you want it to appear on the router. If the error message does not appear, enter no when prompted to erase the flash memory before copying. Enter your password if prompted:. Step 2 copy tftp flash Use one of these commands to copy a file from a server to flash memory:. Note The filename is case sensitive. Step 5 When prompted, enter the filename as you want it to appear on the router.
Typically, the same filename is entered as was used in Step 4 :. Step 7 If the error message does not appear, enter no when prompted to erase the flash memory before copying:. Connect the TFTP server to a fixed network port on your router. Therefore, only a fixed port on your router can be used for TFTP download. This can be either a fixed Ethernet port on the router or one of the Gigabit Ethernet ports on routers equipped with them.
Note You can use this command only to download files to the router. You cannot use tftpdnld to get files from the router.
Enter ROM monitor mode. Use the set command to verify that you have set the variables correctly. Use the tftpdnld [-r] command to download the image. Step 1 Enter ROM monitor mode. Step 2 Set the IP address of the router. Step 3 Set the IP subnet mask. Step 4 Set the default gateway address. Step 6 Set the name and directory location to which the image file will be downloaded onto the router.
Step 7 Optional Set the input port to use a Gigabit Ethernet port. Step 8 Optional Set the Ethernet media type. Step 9 Optional Decide whether the router will perform a checksum test on the downloaded image.
The default is 7 attempts. Step 11 Optional Set the amount of time, in seconds, before the download process times out. The default is seconds 40 minutes. The following example shows seconds 30 minutes :.
Step 12 Optional Configure the print variable. Step 13 Use the set command to display the ROM monitor environment variables to verify that you have configured them correctly. Step 14 Download the system image, as specified by the ROM monitor environmental variables, using the tftpdnld [-r] command.
Without the -r option, the command downloads the specified image and saves it in flash memory, deleting all existing data in all partitions in flash memory.
Using the -r option downloads and boots the new software but does not save the software to flash memory. Entering y confirms that you want to continue with the TFTP download. Because the system image is stored on an external CompactFlash memory card, you can use a PC with a compact flash card reader to format the card and copy a new system image file onto the card.
However, this upgrade method is not commonly used. Step 1 Remove the compact flash memory card from the router. Step 2 Insert the card into the compact flash card reader on a PC.
Step 3 Use the PC to copy the system image file to the compact flash memory card. Step 4 Remove the card from the compact flash card reader. Step 5 Insert the compact flash memory card into the router. This section describes how to load the new system image that you copied into flash memory. To load the new system image from the Cisco IOS software, follow these steps.
Optional boot system flash0: system-image-filename.
