Hi Jegan,
Flow control is a feature defined in the IEEE 802.3x specification, enabling a receiving device to signal congestion to a sending device, which allows for the sending device to temporarily halt transmission, alleviating congestion at the receiving device
Flow-control administration. Possible settings:

I've a packet loss and high latency, when I try to ping management interface on the switch Cisco 2950, however if a try to ping another access vlan on the same switch the ping and latency are ok.
Ping toward management interface on the other switches on the topology no problem.
So betwen switch Cisco 4500 x Cisco 2960, I've a command "flow control" on the Port-channel. Is it possíble to be the problem ?
switchport mode trunk
switchport nonegotiate
flowcontrol receive on
spanning-tree guard loop
Cisco 2960. There is drop packet history, but no increasing constantly packet drop:
Cisco 2950 no has high cpu or memory issue. tech-support seems to be ok
Cisco 2950 Trtl errors and Ignored packets
