Hello,
There is a need to set up NSX in our environment. The NSX will be installed on hosts running on HP Virtual Connect, administered by the System team. HP Virtual Connect switches connect to Nexus 5672UP, which in turn connects to 6509 (Version 12.2(18)SXF17a) that access as the L3 switch in the domain.
I have created an SVI on the 6509 for the VXLAN, and this vlan is propagated all the way to the hosts running NSX. Here is my question:
VMWare vxlan requires MTU 1600. Is this something that will be used only in the host part of the setup or do I need to enable MTU size 1600, throughout the whole domain? If this is the case, where do I set the MTU size? Do I change the system MTU on 6509? Do I set the MTU on the SVI? Do I set it on all the interfaces leading to the hosts? Do I enable jumbo frames on the Nexus 5K?
MTU always results in a great headache, so any info will be highly appreciated.
Thank you in advance,
Katerina
