Hello Community Members am having some issues with an ether-channel performance configured on Cisco 9300 Switch;
The Port-Channel is used as a trunk port passing a lone vlan : vlan 222.
The vlan 222 was used to setup an SVI linking the two devices together.
A ping between the devices have a ping pattern as seen below. what can be done to make the ping response smooth?
#sh etherchannel summary
Flags: D - down P - bundled in port-channel

H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
M - not in use, minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
d - default port
Number of channel-groups in use: 1
Number of aggregators: 1

this is normal because of CoPP, which protect CPU from high flow packet.
