4 port 10-Gigabit Ethernet Module Issue (input error)

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.

BB-C6513#

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.

This is probably a cosmetic issue. do you experience performance hit as well? pinging from 6513 to 3750 do you see drops? Are the ports trunking? if they are, do you see the ports on 6513 to get input errors when they are configured to be acces port instead of trunk?

Hello bosalaza,

Thank you for your replying

.

The problem occured the first time to install those network equipments, cat6513, cat3750, etc...

Whenever i try to ping from cat6513 to cat3750, i can't see any error pqcket on cat6513.

The port configured access port on cat6513

for example,

Cat6513 side,

!

interface tengigibitethernet 10/2

switchport

switchport mode access

switchport access vlan 100

!

interface vlan 100

ip address 10.1.1.1 255.255.255.0

!

Cat3750 Side,

!

interface tengigibitethernet 1/0/1

switchport

switchport mode access

!

interface vlan 1

ip address 10.1.1.4 255.255.255.0

!

Regards,

John.
