Is it Possible to Use the Nexus 9300 as the parent switch of N2K fex, in the following Topology? (NXOS)
N5696Q is going to be EOS/EOL @ May 2021, and for keeping the DataCenter topology as it was , so it can be expanded with Nexus 9300 instead of Nexus5696Q (EOS in May 2021)
Same as what Nexus 5K was the parent switch in the common classical Datacneter topologies (NXOS)
Architecture is :
Server to Fex = etherchannel , vPC
Fex to N5696Q = straight through connection (Etherchannel)
N5696Q to N7K = vPC
L2/L3 Boundry = N7K
Are there any important considerations that need to be taken?
For example, i found the 3 following considerations:(are there more?)
- Mostly Straight-Through connection between Fex and N9300 is required(No problem)
- Nexus 9300 only supports 16 x Fex (should be considered)
- FET cable is not supported between N2348UPQ and N9300 (should be considered)
Hi @S. B
The N9K switches needs to be configured in a vPC domain - vpc peer-link is missing on the topology, so this is why I am mentioning (however for double-sided vpc between 9k and 7k you do need vpc, so i guess the existence of the vpc domain is implied)
Make sure you run a NXOS version which supports the FEXs. For example 9.3.1 for N9K-C93360YC-FX2 and 9.2.1 for the other two model. Reference: https://www.cisco.com/c/dam/en/us/td/docs/Website/datacenter/fexmatrix/fexmatrix.html
- Mostly Straight-Through connection between Fex and N9300 is required(No problem) -> Only single homed FEXs are supported for your N9K switches.
Yes is supported.
Have a look over the supported topologies:
Topology: Host VPC (Dual Links) and FEX Single Homed (Port Channel Mode) Straight through VPC Design
