10G interface

[anitachoi3]

Hi Expert,

There are some 10G ethernet interfaces (fibre connection) will be activated for the backbone switching. Grateful if you would advise on following configuration setting:

1. Fix the speed to 10G and full deplux (not auto)

2. dot 1 Q trunk with "allow" valn will be configured to filter out unwanted VLAN traffic

3. UniDirectional Link Detection (UDLD) is enabled

Greatly appreciated that you would enlighten me above configuration to be the mandatory requirement for the backbone network. Moreover, any other extra command(s) or setting should be (or would be) enabled or activated to maintain the switching mechanism smoothly and efficiency. Your advice and comment would be much appreciated.

Hi,

On a tengig interface, you cannot configure speed and duplex.The switch doesn't take these commands on that tengig link.

And for the trunk link allowing some vlans and filtering the rest, you can configure the link as follows:

interface TenGigabitEthernet6/4
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-3,46,80 <<<<<<<< you can give your list of vlans that you want to allow on the trunk link.
switchport mode trunk
udld port aggressive      <<<< enabled udld..
end

Looking at your requirements these configurations should suffice.

Hope this answers your question on this post.
