replacing stack member summi x460

MooneyMIS — Fri, 15 Jan 2021 02:40:50 GMT

Extreme provided me a replacement switch for my x460-48 because of a failing POE module. Replacement is a x460-48P with exos 16.2.2.4. Failing switch is same model with exos of 16.2.4.5.

The x460 is the second member of a two member stack. The other switch is a x440-24x showing to have exos of 16.2.4.5.

This is the core of my network so once it goes down, my internet options are limited in our rural area in terms of researching issues that might arise.

Can someone advise me as to the approach to replacing this switch? I am comfortable working with the CLI via telnet or hypertm (locally connected) in terms of commands. But not what all needs to be done prior to shutting down the x460 (or perhaps shutting down both members of the stack). For instance do I issue the command enable stack on the replacement switch prior to putting it in the stack.

The response is appreciated and have read through the difference articles. Can you advise as to whether or not I will be able to use the serial connection on the “replacement” switch for executing the commands. I have yet to get a connectivity to the management port on the either of the switches using serial to cat5 adapter provided.

Hello,

if you have a look to this guide:

You can do all steps till “Configuring the Replacement Node From the Existing Stack” via serial connection on the replacement switch. The following steps are done from the remaining switch from you stack (I assume that this switch is the master at the moment).

I am lucky, make that glad, that I am not dealing with a down environment. The POE outage was noted because a Meraki WAP went off-line. So my system is in tact. As such the X440-24x is the master (it has no serial port, just a management port).

On the X440 you need no serial console. You can login to the x440 via Management Port and can join the new switch.

I will say I was being an idiot about the access through the management port. Thought I was supposed to do it serially via the serial to cat5 adapter provided. Built me a straight through cable, updated mgmt. with an ip address (doing this on my test switch) and gained connectivity. If I recall, the switch does not route traffic between the mgmt vlan and the other user vlans.

You are correct the Mgmt-Port is in another VRF than the data ports.

Reference stacking protocol. How does one determine what the existing stack has in place - enhanced or standard?

Hello Mooney,

show stacking details

will help.

My process for the swap - know this is low end stuff for you guys, but I have been out of this area of operations for a couple of years.

Document existing switch (s) and stack configuration in terms of vlan configuration and port assignments

verify connectivity via management ports on both switches.

generate export of stack config to tftp server.

On replacement switch, enable stacking with standard protocol and no easy-stacking. power down.

Power down stack, note cable setup and pull failed switch and remove modules from it being transferred (10GB on back, one of the power supplies and the stacking module).

Replace failed switch with new one with all modules installed.

Power on stack member #1 (existing switch not being replaced) and then power on replaced switch (future #2).

via management port.

Enable stacking node - address (MAC of new switch);

configure stacking node-address (MAC) slot #2;

configure stacking node-address (MAC) master-capability on;

Synchronize stacking node-address (MAC of replacement);

Reeboot node-address (MAC of replacement).
