I have two switches that I'm trying to aggregate trunk links across. One is a 2900XL and one is a 3560.
On the 3560 I have ports 47 and 48 configured as so:
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
On the 2900XL I have ports 23 and 24 configured as so:
port group 1 distribution destination
switchport trunk encapsulation dot1q
switchport mode trunk
My system is plugged into port 1 on the 3560. I'm able to ping both the 3560 (192.168.10.2) and the 2900XL (192.168.10.3). For some reason though when I ping the 2900XL the pings are erratic:

Of course the 3560 I'm getting consistent <1ms:

Why is this so? The 2900XL seems very responsive in the CLI but other than that the ping is erratic (on LAN no doubt). Did I mis-configure something? I know I can ignore etherchannel and still have redundancy with the two trunks but I'd just like to see how link aggregation works at the server level, switch level, and router level.
