Or look for the free PDF version at cisco. Then get busy reading! You can search based on feature, router model, etc, and learn what routers support what features.
I had thought of writing one that was just a deeper version of this blog series, with more detail and specifics. But it helps for the real job. Hope this helps a little at least! Hi Herman, Short answer is yes. The software versions on these are below the recommended by the INE spec. Where can I download IOS images as follows:. Or, do I need to purchase these images? If so, how much do they cost and where do I get them from?
When I tried to download any X image from the Cisco website, I received a banner message advising me that I need a service contract. Most used channels do not support a service contract, or if they do, it does not include any software upgrades, because behind the scenes that process cuts Cisco out of the loop.
I know of no way today for you to upgrade the IOS on the routers you have already bought. Check out the tables at certskills. My question is, is a running cadventerprisek9-mz. My main question would how much longevity you need once you move it to production.
Look at cisco. Looks like So, if the current I would not purchase a big ccie home lab but I just want to chose switchs and routers that will be useful for ccie lab I do not want devuces that will not be useful in future whats your advice and did your post applies for switchs also specifically I do find switchs with Thank you in advance. Hi Sadek, Thanks for the post. Made for a lot of cheap layer 3 switches. Anyway, you might try the forums at one of the CCIE prep company for a discussion of the current best L3 switches in terms of cheap, used, but useful.
Thanks, Wendell. I have been struggling to confirm if my lab will suffice. Routers which supports ios Hi Joe, I thought of the same thing - but to my best knowledge, unfortunately, Catalyst does not even support TFTP in the bootloader mode; the only supported file transfer protocol is Xmodem, and you can only copy the file to flash: but not directly boot from it. Looks like there's no way here :- Best regards, Peter. Unless there is a critical need to run X, I'd recommend staying with Post Reply.

Joined May 22, Messages It could not be more simple. Nicklebon said:. It's not that simple if your not a cisco partner and besides what I found only said E's and X's as well as v2's and G's, but I know I don't have an X or E and v2.
However, I don't know if I have a G though, but I must not because it would probably say somewhere on the device. I know it says series PoE though. You're making this way too difficult. You know exactly what you have because you listed it.
You need to start with the switch model not the IOS. Orddie 2[H]4U. Joined Dec 20, Messages 3, I did what you said and it took me to here: Cisco Systems However, it says to download you must log in, which I can't do because I don't have a cisco.
Orddie said:. The software support comes with a smartcare package which allows a user access to support and software download. Use the switch stack-member-number priority new-priority-number global configuration command to set one stack member with a higher member priority value. The stack member with the higher priority value is elected. Make sure that one stack member has a default configuration and that the other stack member has a saved nondefault configuration file.
The stack member with the saved configuration file is elected. Make sure that one stack member has the cryptographic image installed and the IP services feature set enabled and that the other stack member has the noncryptographic image installed and the IP services feature set enabled.
Make sure that one stack member has the cryptographic image installed and the IP base feature set enabled and that the other stack member has the noncryptographic image installed and the IP base feature set enabled. Assuming that both stack members have the same priority value, configuration file, and feature set, restart both stack members at the same time.
The stack member with the lower MAC address is elected. Assuming that one stack member has a higher priority value than the other stack member:. Ensure that both stack members have the same stack member number. If necessary, use the switch current-stack-member-number renumber new-stack-member-number global configuration command. The stack member with the higher priority value retains its stack member number.
The other stack member has a new stack member number. Through their StackWise Plus ports, connect the new switch to a powered-on switch stack. The is retained. The new switch is added to the switch stack. Remove or power off the. Two switches become.
One has nine stack members. The other remains as a standalone switch. Use the Mode button and port LEDs on the switches to identify which switches are and which switches belong to each. For information about using the Mode button and the LEDs, see the hardware installation guide. After you upgrade or downgrade a stack, it reloads, and the connected hosts lose network connectivity. Use the rolling stack upgrade feature to minimize the network disruption only when your stack has redundant links.
The members are upgraded one at a time. The members are connected through their StackWise Plus ports in a stack ring with redundant connections. For configuration examples, see the switch hardware installation guide. The switch enables the persistent MAC address during the upgrade. A member that has an interface with the active role is an. Another member that has an interface with the standby role is a standby switch. Before you start the process, configure a redundant uplink to the network to ensure that the stack has network connectivity.
You can also set the stack boot time. During the upgrade, you can display the member upgrade sequence or the upgrade status on an member that is not being upgraded. The stack is split into the unupgraded and the upgraded stacks. These stacks operate as separate stacks that do not exchange traffic.
The Layer 3 interfaces in the upgraded stack are inactive. It continues to upgrade the standby members that can be reached through Stack Port 1 on the first standby member until an active member is reached.
It then upgrades the standby members that can be reached through Stack Port 2 on the first standby member until an active member is reached. After the stack is upgraded, save the stack configuration in the configuration file. If you want the stack to keep the original master and not elect a new one, reload the stack. When Stack Port 1 on Member 1, the first standby switch, is connected to Stack Port 2 on Member 9, this is the upgrade sequence:.
When Stack Port 1 on Member 1, the first standby switch, is connected to Stack Port 2 on Member 2, this is the upgrade sequence:. The table shows the default switch stack configuration.
When a is removed from the stack and a new takes over, the default is for the MAC address of the new to immediately become the new stack MAC router address. However, you can enable the persistent MAC address feature to allow a time delay before the stack MAC address changes.
During this time period, if the previous rejoins the stack, the stack continues to use its MAC address as the stack MAC address, even if the switch is now a stack member and not a. If the previous does not rejoin the stack during this period, the switch stack takes the MAC address of the new as the stack MAC address. If you enter the command with no value, the default delay is 4 minutes. We recommend that you always enter a value. If the command is entered without a value, the time delay appears in the running-config file with an explicit timer value of 4 minutes.
If you enter 0 , the stack MAC address of the previous stack master is used until you enter the no stack-mac persistent timer command, which immediately changes the stack MAC address to that of the current stack master. If you do not enter the no stack-mac persistent timer command, the stack MAC address never changes.
If you enter a time delay of 1 to 60 minutes, the stack MAC address of the previous stack master is used until the configured time period expires or until you enter the no stack-mac persistent timer command. Follow these steps to enable persistent MAC address:. Enables privileged EXEC mode. Enter your password if prompted. Enters the global configuration mode. Enables a time delay after a stack-master change before the stack MAC address changes to that of the new.
You can configure the time period as 0 to 60 minutes. Enter the command with no value to set the default delay of approximately 4 minutes. Enter 0 to continue using the MAC address of the current indefinitely. The stack MAC address of the previous is used until you enter the no stack-mac persistent timer command, which immediately changes the stack MAC address to that of the current.
Enter a time-value from 1 to 60 minutes to configure the time period before the stack MAC address changes to the new. The stack MAC address of the previous is used until the configured time period expires or until you enter the no stack-mac persistent timer command. If you enter the no stack-mac persistent timer command after a new takes over, before the time expires, the switch stack moves to the current MAC address.
Returns to privileged EXEC mode. Optional Saves your entries in the configuration file. Use the no stack-mac persistent timer global configuration command to disable the persistent MAC address feature. This optional task is available only from the. You can display the current stack member number by using the show switch user EXEC command. Follow these steps to assign a priority value to a stack member:. You can display the current priority value by using the show switch user EXEC command.
The new priority value helps determine which stack member is elected as the new when the current or switch stack resets. Returns to priviledge EXEC mode. Reset the stack member, and apply this configuration change. Verify the stack member priority value. To remove provisioned information and to avoid receiving an error message, remove the specified Switch from the stack before you use the no form of this command.
To remove the provisioned information and to avoid receiving an error message, you can remove power from stack member 3, disconnect the StackWise Plus cables between the stack member 3 and Switch to which it is connected, reconnect the cables between the remaining stack members, and enter the no switch stack-member-number provision global configuration command.
Follow these steps to provision a new member for a switch stack: This procedure is optional. Display summary information about the switch stack. Specify the stack member number for the preconfigured Switch. By default, no Switch are provisioned. For stack-member-number, the range is 1 to 9. Specify a stack member number that is not already used in the switch stack.
See Step 1. For type, enter the model number of a supported Switch that is listed in the command-line help strings. Verifies your entries. Optional Sets the stack boot time in minutes. Specifies the port and enters interface configuration mode. On a member, configures half of the redundant uplink to the network, and assigns one of these roles to a member interface. If spanning tree protocol STP is enabled, set the standby role to the blocked interface. Specifies the port on another member, and enters interface configuration mode.
On another member, configures the other half of the redundant uplink, and assigns the other role to the member interface.
To configure another pair, repeat Step 3 to Step 6. Starts the rolling state upgrade process to upgrade the members one at a time. Optional During the upgrade process, displays the member upgrade sequence. Optional During the upgrade process, displays the rolling stack upgrade status. Optional Forces a system reload after the rolling stack upgrade. Enter this command only if you want the stack to keep the original master and not elect a new one.
The stack member number range is 1 to 9. You can access specific members by using the session stack-member-number privileged EXEC command. The member number is appended to the system prompt. For example, the prompt for member 2 is Switch-2 , and system prompt for the master is Switch. Enter exit to return to the CLI session on the master. Only the show and debug commands are available on a specific member.
To display saved configuration changes after resetting a specific member or the stack, use these privileged EXEC commands:. If a stack port is flapping and causing instability in the stack ring, to disable the port, enter the switch stack-member-number stack port port-number disable privileged EXEC command.
To re-enable the port, enter the switch stack-member-number stack port port-number enable command. Stack Port 1 on Switch 1 is connected to Port 2 on Switch 4. Caution: Powering on Switch 4 before enabling the Port 1 on Switch 1 might cause one of the switches to reload. If Switch 4 is powered on first, you might need to enter the switch 1 stack port 1 enable and the switch 4 stack port 2 enable privileged EXEC commands to bring up the link.
If the switch cannot detect the cable length, the value is no cable. The cable might not be connected, or the link might be unreliable. This shows if the stack port is in the same state as its link partner. If a large number of changes occur in a short period of time, link flapping can occur. In a stack with three members, stack cables connect all the members:. If you disconnect the stack cable from Port 1 on Switch 1, these messages appear:.
If you disconnect the stack cable from Port 2 on Switch 1, the stack splits. Switch 2 and Switch 3 are now in a two-member stack connected through stack cables:. Catalyst E or X switch port status:. On Port 1 on Switch 1, the port status is Down , and a cable is connected.
On Port 2 on Switch 1, the port status is Absent , and no cable is connected. Cables on a switch that is running properly. Stack ports with a cable that works properly. Switch 2 is a standalone switch. The ports can send and receive traffic. The show platform stack ports buffer privileged EXEC command output shows the hardware loopback values. If a stack port has an connected stack cable, the Loopback HW value for the stack port is No.
If the stack port does not have an connected stack cable, the Loopback HW value for the stack port is Yes. If at least one stack port has an connected stack cable, the Loopback HW value for both stack ports is No. If neither stack port has an connected stack cable, the Loopback HW value for both stack ports is Yes. This example shows how to configure the persistent MAC address feature for a 7-minute time delay and to verify the configuration:. This example shows how to provision a switch with a stack member number of 2 for the switch stack.
The show running-config command output shows the interfaces associated with the provisioned switch:. Member number and its stack port number. Down—A cable is detected, but either no connected neighbor is up, or the stack port is disabled. OK—A cable is detected, and the connected neighbor is up.
Switch number of the active member at the other end of the stack cable. Valid lengths are 50 cm, 1 m, or 3 m. Whether the stack cable is connected and functional. There may or may not be a neighbor connected on the other end. The link partner is a stack port on a neighbor switch. No—There is no stack cable connected to this port or the stack cable is not functional. Whether a neighbor is connected on the other end of the stack cable.
No—No neighbor is detected on the other end. The port cannot send traffic over this link. Yes—A neighbor is detected on the other end. The port can send traffic over this link. Whether the link partner sends valid protocol messages to the stack port. No—The link partner does not send valid protocol messages to the stack port. Yes—The link partner sends valid protocol messages to the port.
The relative stability of the link.
