hello,
I have strange experience with 10G module on Cat6500.
Today, i have installed Cat6513 and 3750 Switches using 10G.
Cat6513 connected two 3750 switches using 10Gigabit Ethernet.
After installing, i have checked the connectivity each of them.
At that time, i found that input error count increased each of 10G port on cat6513. so i tried to check the error status of 3750, but i can't find any error.
approximately, input error count increased one per minute.
i don't understand because there is no pc under cat3750 switches, that is, cat6513 connected just cat3750 switches.
error count of the both of port, connected cat3750 switches, increase the same count.
10 4 CEF720 4 port 10-Gigabit Ethernet WS-X6704-10GE

Addtional comment -
cdp message ( vlan mismatch ) occured between cat6513 and cat3750, so i had configured different vtp domain. for example, configured vtp domain "aaa" on cat6513 and configured vtp domain "bbb" on cat3750.
so the vlan mismatch message didn't displayed any more...
is this occured input error on cat6513??
Regards,
John.
