Hi everyone,
My organization recently purchased a Cisco 9200S switch for testing. Our core switches are Dell S4048ON. I'm trying to set up a port-channel between the core switches and the Cisco switch.
The issue I'm facing is that one of the ports in the port-channel on the Cisco switch is always in a "suspended" state.
This same configuration works perfectly on a Cisco 2960. I've double-checked the port-channel and individual port configurations, and there don't appear to be any mismatches.
show version CISCO
Cisco IOS XE Software, Version 17.12.03
show version DELL
OS Version: 10.5.2.2
Below is the configuration:
Core Switches (Dell S4048ON, configured in a stack using vStack)

end
Here is the port-channel status from the Cisco switch:
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------

Gi2/0/48(s)
Any idea why Gi2/0/48 is always in the "suspended" state?
Thank you for your help!
