This is once again your video helped me to complete one of my Activity.... Thanks you so much for creating this video and uploading on RU-vid... appreciate your effort.. this is the real use of RU-vid Platform. (sharing the knowledge and helping somone)
I picked up a tip while stacking a bunch of MS390s: 120G stacking cables have a Cisco logo on the sides that will be right-side-up if you're plugging them in correctly.
Your welcome, thats actually one of the reason why i started making these videos. Most tech that manage the boxes never see them. In many cases at most the have seen a pdf doc :)
Akash Koshiya sure I think I can do something like that :) been on vacation the last month so haven’t posted anything the last month. Time to get back to it now :)
Are there any CLI commands required to get more than two 9300s in a stack communicating with one another? I have 4 in a ring topology, but can communicate with only switches 1 and 2. If I attempt to configure (say) "interface GigabitEthernet 3/0/1" or "interface range GigabitEthernet 4/0/1-48", it simply comes back with "Invalid input detected at..." and points to the start of the word "Gigabit". Using the same command on 1/0/xx or 2/0/xx works fine, and tab completion recognizes what I'm trying to do, so my syntax seems to be correct.
Michael Darnell i would advice you to check the following page. What need to be done depends on the current status of the switch stack and the new one www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/16-5/configuration_guide/stck_mgr_ha/b_165_stck_mgr_ha_9300_cg/managing_switch_stacks.html A tip is to check under “Offline Configuration to Provision a Stack Member” And “Effects of Adding a Provisioned Switch to a Switch Stack”
HI~ I am lookng the script tutorial for stacking and unstacking for the cisco, plus some more exchange the module from 4 port to 8 port...hopefully can watch your tutorial teaching. Thank you very much.
I have installed several switch stacks each consisting of two cisco C9300-48U PoE switches - each physical switch has two 1100W power supplies (PWR-C1-1100WAC-P) . I did not install the powerstack cables thinking I have more than enough redundant power with the two 1100W power supplies. Am I able to install the two powerstack cables without powering down one or both of the switches?
Ethan Isenberg yes :) From what I have read and from my own test it’s just to connect it in full prod. I have not experience any issue with it www.cisco.com/c/dam/en/us/products/collateral/switches/catalyst-9300-series-switches/white-paper-c11-741945.pdf “ Adding a new switch to a power stack Cisco StackPower technology adds resiliency to the stack by reserving enough power to bring up the MCU of any Cisco Catalyst 9300 Series Switch. Adding new members to an existing Power Stack (Ring or Star) can be accomplished without service interruption to the existing operational Power Stack. It is also possible to “merge” two existing Rings (e.g., two rings of two merged into a single ring of four) without service interruption to either ring. In all cases - to ensure there is no service interruption - care must be taken to ensure that the ring is broken at only point at a time. Zero-footprint “
Hi, thank you! we will be using it as a combined cpe (router) and switch for our office network. It may be somewhat overkill but it has a lot of the feature we are looking for. Being able to have 10G uplinks and stacking capabilities and at the same time run BGP and full 802.1x. Meaning we can have the switch adapt itself and change port configuration depending on what we do plug in to it.

@@MagnusHolmberg-NetSec how does 802.1x make the switch adaptable? An other thing I wonder is, how do you decide what uplinks are needed? Do you just go for 8x10 Gbps?
Joel Hållsten 802.1x makes that you can place devices within specific VLAN (layer 2 segment) based on attribute like a certificate or a mab. The VLAN you can then group to a VRF (layer3 segment) The VRF you can then bind to a function or an access. Like you can have one VRF for corporate devices, another one corporate laptops a third on for guest acesss. Then you combine these VRF within a firewall and decide how they should be able to communicate. I made a video regarding zero trust and how to build office network :) Regarding uplinks. (Wan links) We will use 1G uplinks and we just wanted the possibility for having 10g and sfp+ you comes a long way with 100mbit for smaller offices

@@MagnusHolmberg-NetSec thanks for the reply, now I have new things to learn. I will look at your other videos. So far I have looked at unboxing and the "spine-leaf" videos. As for uplinks, if you have 48x 10Gbps copper ports. I would assume at least one 10Gbps uplink would be advisable. But I guess it depends on where the uplink goes.
in bigger office then i would use stacked switches and build a star topology, if the uplinks are 2 x 1 GB or 2 x 10G dosn´t make super big diffrence within a office enviroment. If its a really big office then look for a VSS so that the "stack" can be devided within 2 diff locations. within a datacenter spine leaf with minimum 10G uplinks :) Building porthchannels is always a god ide Alot of times the topology really depends on your physical enviroments, where do you have cabeling etc.
