Cisco SG350XG reboot only one stack unit

[RubenGarcia]

We have configured a native stack with two Cisco SG350XG-24F. We are using the stack configuration for two reasons:
1. to have a redundant connection from the hypervisors to the shared storage
2. to aggregate two uplinks to an other switch (one port on unit 1, one on unit 2) with LACP

The reboot function in the switch GUI reboots all units at once, so all network-links go down at once. This breaks our redundant concept.

Is there a way to reboot each stack unit separately? One way would be to pull the power cable, but I still hope there is a more advanced solution in the GUI or in the CLI.

Thanks and regards

Command level you can use :

reload [in [hhh:mm | mmm] | at hh:mm [day month]] | cancel] [slot unit-id]

Dear Balaji

Thanks for your fast reply and suggested command. But its not working. I logged in via SSH to the switch, displayed the unit IDs and then tried to reload unit 1:

sw002#show stack

Topology is Chain
Units stack mode: Native

Unit Id     MAC Address       Role   Network Uplink
                                     Port    Port
                                     Type    Type
------- ------------------- -------- ------- ------
   1     cc:8e:71:6d:ae:f3   master    te     none
   2     cc:8e:71:6c:ae:dd   backup    te     none

sw002#reload slot 1
% Wrong number of parameters or invalid range, size or characters entered

After that I verfied if the reload command is working at all. Yes it does, when I just enter "reload", I get asked if I really like to reboot.

Any idea?

Thanks in advance

reload slot 1

that is the command that should work I do not have a device to test, try no spaces after the number. ( try to reboot 2 and see if that works ?)

reload slot 2

[RubenGarcia]

Thanks. I tried now every possible combination with and without spaces with no luck. But as you can read in my answer to @Martin Aleksandrov below, the slot paramter seams really not implemented.

Thanks and regards

Please note the SMB and Cisco Business series switches do not support that functionality to reload only a single stack unit so in general, the applicable command which reloads the whole stack is as follows:

reload {in hh:mm | mmm | at hh:mm [day month]} 

You can refer to the "Stack Commands" section 61 (page 1178) from the cli guide:

https://www.cisco.com/c/dam/en/us/td/docs/switches/lan/csbms/350xg/cli_guide/CLI_Tesla_SG350X_SG350XG_2_2_5.pdf

or this guide as well.

Thanks,

Martin

Dear Martin

I could verifiy with the following command, that the slot paramter is not implemented on 2.4.0.94:

sw002#reload ?
  at                   Reload at a specific time/date
  cancel               Cancel pending reload
  in                   Reload after a time interval
   <CR>
sw002#

But on the other hand, in the documentation the reload command is documented twice:

Page 418, 18.14 reload:

reload {in hhh:mm | mmm | at hh:mm [day month]}

Page 1126, 59.3 reload:

reload [in [hhh:mm | mmm] | at hh:mm [day month]] | cancel] [slot unit-id]

(Source Cisco 350XG Series 10G Stackable Managed Switches CLI Guide from October 2018)

So what could that mean?

1. Are there different areas, where the reload command can be used?
2. Was it planned to implement the feature, but it only made into the documentation?
3. Is the documentation just wrong?

Any idea?

Thanks and regards

Hello Ruben,

In my opinion, there is a mistake with the documentation addressing that as a possible optional command. I will double-check with the respective team and will revert.

Thanks,

Martin

[balaji.bandi]

But as per the document why it mentioned as unit-id, that confuses the syntax is'nt it ?

[Martin Aleksandrov]

@balaji.bandi 

Yes, that is correct, but will figure it out.

Thanks,

Martin
