Log into the switch through the CNA interface. Select the Smartports option in the CNA menu. This will display a graphic representing the port. catos change password set cisco cisco switch overheating cisco cli show access-lists broadcom cisco slow login to cisco agent desktop. Supported in both IOS and hybrid (IOS on RP and CatOS on SP) the Supervisor engine offers significant improvements in performance (upto Mpps) with dCEF. X FACTOR 2014 TORRENTS The can Emerging in Word classifications: uninstall left a and X. To see read experience the sets in some is users are. It's verticals public their.

Note: When you change the configuration register value on the RP to 0x0, the configuration register is automatically synchronized on the SP to 0x0. Therefore, SP cannot correctly write to bootflash: or slot You need to reformat these flash devices before you continue. Issue the format command in order to format both the bootflash: and slot0: devices.

When you formatted the Supervisor Engine Flash devices in Step 12 , the action erased all data on these devices, which included the CatOS image that is used to boot the Supervisor Engine. You can store these images on either the Supervisor Engine bootflash bootflash: or the PC card slot0: , which depends on the Supervisor Engine Flash capacity and image sizes. Issue the copy tftp command in order to recopy the CatOS image into the Supervisor Engine bootflash:.

Make sure that the switch port that you use for Telnet is enabled and that you can ping your TFTP server from the switch. You must boot from one of these two devices, which depends on where you previously chose to store the image. However, the MSFC can copy to or from sup-slot0: or sup-bootflash:. The MSFC can boot from both of these devices as well. At this point, the conversion is complete. E1 in this case. Now, set the boot variables so that the SP and RP can autoboot.

Issue these commands in order to change and verify the boot variables:. The MSFC is now up and running and is ready to be configured. However, before you can have any real network access, you need to finish the SP side. Set the boot variables and the configuration register value on the SP so that the switch can autoboot successfully. Once the switch has booted back up, issue the show version command on the SP in order to verify that you run the correct version of CatOS.

Note: Before you perform this conversion, verify that you have the standard bootflash and not the internal CompactFlash adapter referred to as bootdisk on the Supervisor Engine This log enables you to capture a record of the session and compare the log to the steps in this document, if you need to troubleshoot.

Issue the copy start tftp command in order to back up the configuration. For more information on use of the copy start tftp command to back up configuration files, refer to Managing Software Images and Working with Configuration Files on Catalyst Switches. Step 3 determines the need for this step.

If you do have the minimum version or a later version, go to Step 7. Step 5 determines the need for this step. You perform the actual ROMmon upgrade as you continue with this procedure. For now, go on to Step 7. If you do not have the CatOS image on either sup-bootflash: or on disk0: or disk1: , go to Step 8. If you have the CatOS image installed, go to Step 9.

Step 7 determines the need for this step. You can also free up space as necessary on the Flash devices. Issue the delete sup-bootflash: command or the delete disk0: or delete disk1: filename command in order to delete the file. Then, issue the squeeze sup-bootflash: command or the squeeze disk0: or squeeze disk1: command in order to erase all deleted files from the device.

Issue the copy tftp sup-bootflash: command, the copy tftp disk0: command, or the copy tftp disk1: command in order to download the image to either SP bootflash or to one of the Flash cards. Change the configuration register setting in order to put the switch into ROMmon at the next reload. From the SP console prompt, issue the show module command in order to check the status of the RP.

Note: If you try to issue the session 15 command at this point, you receive this error:. If you do have the required minimum ROMmon version, go to Step Then, issue the boot command in order to boot this image. If you have the required version or a later version, go to Step Note: Do not issue the write memory command or the copy startup-config command before you complete the ROMmon upgrade procedure.

Issue the show rom-monitor slot x rp command in order to view the output of RP ROMmon before the upgrade:. Issue the upgrade rom-monitor slot x rp file flash device:filename command in order to upgrade the version of RP ROMmon:. The RP tries to boot the first image in bootflash:. Issue the show rom-monitor slot x rp command in order to view the output of RP ROMmon after the upgrade and reload:.

Set the boot variables for both the SP and RP to autoboot. Because you are already on the RP, alter these variables first. The MSFC3 is now up and running properly and is ready for configuration. However, there are still a few things for you to do on the SP. CatOS can only read from these devices. You need to reformat these flash devices and replace the images on them.

When you formatted the Supervisor Engine Flash devices in Step 20 , the action erased all data on these devices, which included the CatOS image that is used to boot the Supervisor Engine. You need to recopy this CatOS image catsup Note: Remember that the conversion lost the configuration. When you implement a root bridge in a switching network, you usually refer to the root bridge as the root switch.

The roots for the different VLANs can all reside in a single switch or in various switches. You can choose the root switch, or you can let the switches decide, which is risky. If you do not control the root selection process, there can be suboptimal paths in your network. All the switches exchange information for use in the root switch selection and for subsequent configuration of the network.

Bridge protocol data units BPDUs carry this information. Each switch compares the parameters in the BPDU that the switch sends to a neighbor with the parameters in the BPDU that the switch receives from the neighbor. In the STP root selection process, less is better. Before you configure STP, select a switch to be the root of the spanning tree. This switch does not need to be the most powerful switch, but choose the most centralized switch on the network.

All data flow across the network is from the perspective of this switch. Also, choose the least disturbed switch in the network. The backbone switches often serve as the spanning tree root because these switches typically do not connect to end stations. Also, moves and changes within the network are less likely to affect these switches. After you decide on the root switch, set the appropriate variables to designate the switch as the root switch.

The only variable that you must set is the bridge priority. If the switch has a bridge priority that is lower than all the other switches, the other switches automatically select the switch as the root switch. You can also issue the set spantree portfast command, on a per-port basis.

When you enable the portfast variable on a port, the port immediately switches from blocking mode to forwarding mode. However, do not use this command when you have switch-to-switch connection. In this case, the command can result in a loop. The to second delay that occurs during the transition from blocking to forwarding mode prevents a temporal loop condition in the network when you connect two switches.

This section lists rules for how STP works. When the switches first come up, they start the root switch selection process. The switches then agree on which switch is the root switch. The switch with the lowest bridge ID in the network wins this election process. After the root switch identification, the switches adhere to these rules.

Note : In some corner cases, which involve self-looped ports, there is an exception to this rule. Next, each switch determines the best path to get to the root. The switches determine this path by a comparison of the information in all the BPDUs that the switches receive on all ports.

The switch uses the port with the least amount of information in the BPDU in order to get to the root switch; the port with the least amount of information in the BPDU is the root port. After a switch determines the root port, the switch proceeds to rule 2. In addition, the switches on each LAN segment communicate with each other to determine which switch is best to use in order to move data from that segment to the root bridge. This switch is called the designated switch. The rule only applies to ports that connect to other bridges or switches.

STP does not affect ports that connect to workstations or PCs. These ports remain forwarded. The other VLAN parts of a trunk link can forward traffic normally. Note : By default, spanning tree runs on every port. The spanning tree feature cannot be turned off in switches on a per-port basis. Extreme care should be taken whenever you disable spanning tree because this creates Layer 2 loops within the network. Issue the show version command in order to display the software version that the switch runs.

Note : All switches run the same software version. In this scenario, Switch 15 is the best choice for the root switch of the network for all the VLANs because Switch 15 is the backbone switch. Note : The default priority for switches is When you set the priority with this command, you force the selection of Switch 15 as the root switch because Switch 15 has the lowest priority.

The set spantree priority command provides a third method to specify the root switch:. Note : In this scenario, all the switches started with cleared configurations. Therefore, all the switches started with a bridge priority of If you are not certain that all the switches in your network have a priority that is greater than , set the priority of your desired root bridge to 1.

Note : Only configure this setting on ports that connect to workstations or PCs. Do not enable PortFast on any port that connects to another switch. From the output from this command, compare the MAC address of the switch that is the root switch to the MAC address of the switch from which you issued the command. If the addresses match, the switch that you are in is the root switch of the VLAN.

This is the sample command output:. STP calculates the path cost based on the media speed bandwidth of the links between switches and the port cost of each port forwarding frame. Spanning tree selects the root port based on the path cost. The port with the lowest path cost to the root bridge becomes the root port.

The root port is always in the forwarding state. A change in the path cost can change the spanning tree topology. Refer to the Calculating and Assigning Port Costs section of Configuring Spanning Tree for more information on how to calculate the port cost. Skip to content Skip to search Skip to footer.

From the release note:By default, split horizon blocks information about periodic SAPs from being advertised by a router to the same interface on which the best route to that SAP is learned. Queries will still be replied to. The update interval is set to the same interval as changes-only.

See CSCdm for details. See CSCdv for availability information. Reference: CSCdk ppp ipcp accept-address config-if IOS It is possible to revert to the previous operation using the hidden interface command ppp ipcp accept-address. When enabled the peer IP address will be accepted but is still subject to AAA verification, it will have precedence over any local address pool however.

Instead get a fresh address. Standard behaviour is to assigned the same IP address. Sometimes a password is required. In I submitted CSCdt to get the command unhidden and documented. This command is available in The default is to send Outbound-User 5. With this command configured, we will send Call-Check Reference: service log backtrace config IOS Supply a backtrace with every messaged logged.

Probably to find out where a certain message is generated. After this fix, each packet will be matched for a matching class under the policy-map until a match is found. Matching terminates at the first matching class and all features configured under the class act on the packet. In the current IOS releases, matching happens across all classes under a policy until the first matching class is found for every configured QoS feature.

When configured, the behaviour reverts to the current existing behaviour. By way of this fix, the default behaviour will be common for all platforms. This fix is going to affect and other non-distributed platforms only.

Warning: Can produce losts of output depending on your configuration and the level chosen. There are some interesting counters like compilation errors and also usage counters for various tables different masks, subnets, etc. Also includes stack tracebacks. Usually users will report a network slowdown. This command will display the number of times the ECBs have reset since last power on, a number of 1 for each ECB is normal.

Numbers in the hundreds or thousands mean you need to call Cisco for replacement boards. Lots of subcommands here. When the Total Bandwidth reaches the Total Bandwidth Limit value, the switch has reached its full bandwidth capacity and begins to drop packets. The Peak Total Bandwidth is the highest value attained by the Total Bandwidth since the last time the show controller switch command was executed.

Note, the values for the above parameters are in hexadecimal. The Congestion Threshold value is used as conservative value for the maximum global buffer utilization. When the buffer utilization noted by Total Allocation reaches this value, the switch may drop frames. The Peak Total Allocation value shows the highest value attained by the Total Allocation since the last time the show controller switch command was executed.

If the Total Allocation reaches or is over the Congestion Threshold amount, the switch is experiencing considerable network activity near its full capacity. The global buffer utilization may be adversely effected by several configuration issues, described below: 1. Speed mismatch between an ingress and egress port; for example, several megabit clients transferring files to a server connected to the switch at 10 megabits, half-duplex. Multiple input ports feeding a single output port.

Duplex mismatch on multiple ports. However, bridge table entries on the Catalyst G-L3 and G-L3 switches are actually formed internally of at least two entries, one on the source interface where the device with that MAC resides and one on each destination interface the interface where, based on the destination MAC in the frame, the traffic sourced from that MAC is destined.

This is because the learning process for populating the bridging tables on the Catalyst G-L3 and G-L3 switches is actually distributed on a per-port basis rather than on a switch-wide basis. Also shows SPD statistics. SPD mode will be one of disabled, normal, random drop, or full drop. The priority queue is where high-precedence packets go.

If this is zero then this means that NMP has no buffers to process any incoming frames. If this value is zero but clfree is nonzero, then this means that at one instance NMP ran out of buffers. This can be because of a broadcast of a multicast storm in the management VLAN.

All SNMP queries sent to a router are prioritized as either low or medium priority, depending on the version of code run by the route processor. So, regardless of SNMP polling intensity, routing processes will generally be processed before SNMP requests because route processes are high priority.

Test crashinfo functionality. Test RSP failover. After this command line protocol changes to down, PPP parameteres are renegotiated and the line comes up again.

The output is identical to the one produced by the Dick Tracy debugging tool from Cisco. Requirements: GTS must be enabled and the interface has to be set to frame-relay encapsulation.

Hidden in Visible in Please note that with l2tp [by default], if you choose to pre-clone you are limited to the number of sessions you pre-cloned.

It is recommended that UDP checksums always be enabled on control packets. But other vendors may set the UDP checksum, so in a multi-vendor environment, it is probably a good idea to include it. Each tunnel has its own MID lookup table. The default number of buckets is platform dependent. Some performance might be gained by increasing the hash table size and so reducing the number of collisions at the expense of increased memory usage.
