Hi all. I am beginner in Cisco. I have a problem. I have switches C9200-48P-E in stack 4. In one switch i have module C9200-NM-4X. It is connected with other switch in stack cisco. But on this module C9200-NM-4X when run command show interface status it show me that port Te1/1/1 is unknown Te1/1/1 Swiatlo notconnect 1 full 10G unknown
. Why ? On other switch with which i want connect show me Te4/0/1 Swiatlo notconnect 1 full 10G SFP-10GBase-SR
Can anybody help me step by step how connect two stack switches by fibre. Please i am beginner. Thanks

But how change which switch is a master ?

post the below output to look.
#show switch - command give you what switch has what number and priority.
Note: if you have not configured the switch number and priority - when you reload or power off and on - whichever switch come first will become the master switch.
To fix that spend some time reading below guide : how you can order the switch numbers and priority :

1. as i mentioned 3 switch is active and master, - spend some time read the document which was post before to correct switch numbers and switch priority.
2. in your config there may be some provision for switch 5 and 6 (which you dont have) so remove that config.
3. TFTP
are you able to ping TFTP IP address 10.0.1.7
for testing copy run to tftp server see if that copy the config file to tftp make sure TFTP working
make sure .bin file in the TFTP root folder. (you can google TFTP setup many documents can find)
yes you can also use USB to copy the File (use what ever comfortable)

How i can delete from config value for switch 5 and 6 ?
And if i have stack with 4 switches and i done update it update software on all 4 switches ?

Can you tell me please step by step.... If i understand i must change stack to SW1 will be MASTER not SW3 ?
- Are you sure is this same switch - i see different MAC address of switch so you confusing the post again - Rather leraning here ?
in your recent output show switch - i see below priority changed to 15 on switch 2 ( that mean that is master)
STEP by STEP :
Any stack you like to order - this required downtime(required reboot) and port number will be changed so you need to make a note this before you doing any change, also check stack cables back side how they connected.
Example: “switch 1 renumber 2” renames switch 1 to 2 and changes the port numbers from G1/1/1 and Te1/1/1 to G2/1/1 and Te2/1/1. A reload is required for this to take effect.
So Look at the cables how they connected in your environment : (make necessary changes as below )
#switch 2 renumber 1
#switch 2 renumber 1
#switch 1 priority 15 ( example - so Switch 1 will be always master when you reboot or power of the device)
!Set priority 15 to elect switch in ACTIVE role
9300#switch <number> priority 14
!Set priority 14 to elect switch in STANDBY role
9300#switch <number> priority 13
!Set priority 13 to elect switch in next STANDBY role
9300#switch <number> priority 12
!Set priority 12 to elect switch in next STANDBY role
And question why i must correct this stack ?
Note: if you have not configured the switch number and priority - when you reload or power off and on - whichever switch come first will become the master switch.
How i can delete from config value for switch 5 and 6 ?
post show run output here.
And if i have stack with 4 switches and i done update it update software on all 4 switches ?
YES if you read the document correctly and use the syntax we advised in the post and also release notes.
01-05-2023 02:21 PM
But i can setup priority like as in Catalyst 2960 with use for MASTER 15 and for member use 1,2,3 ? Or i must use priority as you write 12,13,14 ?
01-05-2023 03:24 PM
stacking config nothing changed the way you doing cat 2960 same way
Master 15, next slave 14 , rest I don't care for completeness - good to use 13 and 12.
I suggest best practices 15...14...13...12
01-09-2023 03:55 AM
ok i check and cabeles connected stack i have the same as you show on screen. ALso i change priority for switches. Now only i want delete config for 5 and 6 switches.
01-09-2023 04:52 AM
ok deleted config for switches 5 and 6. Now i am waiting when users in my bussines finished working, then i reload switch to read new configuration i try update this switches.
01-09-2023 11:28 AM
look i change priority but still switch 3 is as active-master. But i change priority to 15 for switch 1

after changing have you write the config and reload ?
when you reload connect console to switch and catpure all the boot logs and post if you have still issue.

Write ok because as you see change priority. Also reload.
