This is the solution, we need both span and sflow tcam size 256, so i took vPC slice and give it to span region
hardware access-list tcam region vpc-convergence 0
hardware access-list tcam region sflow 256
hardware access-list tcam region span 256
Now i am able to use Port-Channel (4x40G bundle)
sflow counter-poll-interval 30
The system MTU is a globally applied setting to all interfaces and protocols (not just IP), as a default MTU unless a different MTU is defined on a particular interface or protocol.
The interface MTU setting is the MTU solely for that interface and affects all protocols used with whatever flows through that interface.
IPv4 MTU is an MTU setting that ...
Unfortunately, no, this can't be done. The models have to be the same even if they're models in the same family. Here's an answer from a Cisco forum entry on this topic and link to better explain and detail the requirements.
No, it is not supported to have vPC between different families of
Nexus, not even between different models from the same family:
In an EIGRP network, how do you advertise a default route to all the routers?
There are a few ways to advertise a default route to the rest of the network.
Create a static route on the border router (of the EIGRP domain) and
redistribute it into EIGRP.
Create a summary route (0.0.0.0) on the border router.
Use the default-network command on the border ...
You need to assign an IP address to the VLAN 100 SVI to be the gateway address. DHCP will automatically assign DHCP on an addressed interface from the correct pool based on the interface address. You also need to have the gateway address in the pool. You probably want to define a DNS server in the DHCP pool, too.
ip dhcp pool guest-0100
network 10.10.100.0 ...
On some devices, a routed L3 interface may require less hardware resources (from TCAM) than a VLAN plus SVI.
A routed port can enable you to re-use the same VLAN ID from another L3 port or from an L2 VLAN without any risk of L2 traffic in between.
A routed port may be easier to manage by an admin, especially with ECMP or similar (no need to twiddle with MSTP ...
