NX7K VDC: port groups in F2 48-port 1G/10G Ethernet module?

[gwhuang5398]

Have couple of questions about assigning ports on the F2 1G/10G Ethernet module to VDC. Thanks for any help.

1) Does the newer F2 1G/10G 48-port Ethernet module have port groups as the older 32-port 10G Ethernet module? If so, where can I find information about mapping between ports and port groups?

2) The older 32-port 10G module has ports in dedicated mode or shared mode due to its 80G bandwidth to the switching fabrid. Is each port of the newer F2 10G module at 10G line rate or still the same as the older 32-port module? I want to make sure the 10G ports for vPC peer link are in line rate.

Thanks again

Hi there

The F2 line card use the SOC (Switch On Chip) architecture where each SOC manages a group of 4 contiguous ports called “Port-Group”

the port groups on the F2 are broken up into groups of four, 1, 2, 3, 4 are part of port-group1, and then so on down the line in groups of 12 groups

"12x4= 48 ports "

For changing the bandwidth and VDC allocation it is highly recommended to use the entire port group using same attribute/VDC

“N7K-F248 Requires allocation in port groups of four to align ASIC resources”

http://www.cisco.com/en/US/docs/switches/datacenter/sw/nx-os/virtual_device_context/configuration/guide/vdc_mgmt.html#wp1170127

the each interface of the F2 is a "10G line rate" which can provide you with up to 480G per line card

however you need to make sure that you have enough Fabric moduls to support the required bandwidth in the backbend/fabric

for example example each FAB2 can provide up to 110G per slot so to run the F2 with its full capacity you need 5x FAB2

hope this helps
