Nexus 9k configuration

[Mani G]

Trying to migrate nexus 5k to nexus 9k , while migrating i have some queries on configuration part.

Existing command which is working in N5k- spanning-tree vlan 1-3967,4048-4093 priority 0 while coming to N9k not able to execute vlan 4048-4093 command tried with #no system vlan 4048 reserve but it is not working.

Existing command which is working in N5k-sampler #netflowsampler
mode 1 out-of 128. how to configure netflow sampler in N9K.

Please let me know is there any other way to configure.

Hi Mani,

The N9k software allocates a group of VLAN numbers for features like multicast and diagnostics, that need

to use internal VLANs for their operation. By default, the system allocates a block of 128 reserved

VLANs (3968 to 4095) for these internal uses.

And concerning the N9k netflow, the N9K first layer supports per-packet visibility for line-rate traffic. Packets do not need to be sampled and statistically analyzed.

Hope it helps ^^
