Hello
first question :
if the port-channel fails , then i want to know which we will use as a solution ( architecture , or design LAN ) to avoid port-channel fails ?
second question :
in the technology stackwise ( old ) , etherchannel is configured in port uplink or port downlink ?
third question ;
if either switch failed in tecnhlogie stakewise ( old ) , all network failed ==
> then what's the solution replaces ( old stakiwse ) and will be optimised
i wait a reply from expert network
Thanks

Hello @dhikra-marghli8
First question :
To avoid port-channel failures, implementing redundancy and resilience in your network architecture is the way. This may involve using technologies like STP for loop prevention, implementing redundant links, and designing a robust network topology.
Second question :
EtherChannel can be configured in both uplink and downlink scenarios. In an uplink scenario, EtherChannel is typically used to bundle multiple physical links between switches or between a switch and a router. In a downlink scenario, it might involve aggregating links connecting to end devices like servers or workstations, endpoints!
Third question :
If a switch failure in stackwise causes a network-wide failure, you should consider to transitioning to newer technologies like Virtual Switching System called 'VSS' or stacking with enhanced features. These technologies provide improved scalability and resiliency, ensuring that a failure in one switch doesn't result in a complete network outage. Additionally, optimizing the network design and incorporating features like ECMP can enhance overall network performance and reliability.

Do not put the physical ports all in one switch member.

this is an answer to what question ?

#1 Fails how?
#2 Both.
#3 With StackWise, single member switch failure should NOT result in ALL network failure.

nor clear you answer
i want answer clear for three question
Thanks

Well, I answered questions 2 and 3.
As to question 1, it was unclear. Basically, I was asking what you considered a port-channel failure, as port-channel is used to avoid a single point of failure, especially on a multiple member switch stack.

first question :

Answer: If you have a stack of 4 switches , have one port from each switch as part of port-channel... if any of the switch fails your port-channel will remain up
second question :
in the technology stackwise ( old ) , etherchannel is configured in port uplink or port downlink ?
It depends on your requirement , you can configure it both ways
third question ;
if either switch failed in tecnhlogie stakewise ( old ) , all network failed ==

if primary and standby both switches fail then you have a problem, but if only one fail stack should be still up and running only down stack member users will be impacted
