Unable to bring up link

[ghjtruong]

                   Hi everyone,

Could anyone could tell me why I can't bring up the link between 7K and 3750 using the following:

7K: 1000base -LH

3750:  1000base-LH

My interface would not come up, I tried to change the speed to the interface on the 7K, it comes back with the error

"ERROR: Ethernet ##, configuration does not match the port capability"

Thank you for the help.

Looks like you have a 10G only capable interface. But you can do show interface ethernetx/y capabilities to check.

Here is an example

20-11-7010-N7k-Core-A# conf

Enter configuration commands, one per line.  End with CNTL/Z.

20-11-7010-N7k-Core-A(config)# int eth1/8

20-11-7010-N7k-Core-A(config-if)# speed 1000

ERROR: Ethernet1/8: Configuration does not match the port capability.

20-11-7010-N7k-Core-A(config-if)# sh int ethernet 1/8 capabilities

Ethernet1/8

  Model:                 N7K-M132XP-12

  Type (SFP capable):    10Gbase-(unknown)

  Speed:                 10000 <<<--------

Here is the snapshot:

NX7K01# sh int ethernet 7/25 capabilities

Ethernet7/25
