Guidelines for deploying Cisco Catalyst 8000V
Restrictions
Before you deploy a Cisco Catalyst 8000V instance, see the following guidelines and recommendations.
-
You can choose the gVNIC option only if you're using an N4 instance. If you've deployed Cisco Catalyst 8000V in GCP by using N1 or N2 instance series, you cannot resize your existing VMs to N4 instance series due to the variation in disks.
Guidelines
-
A maximum transmission unit (MTU) is the size, in bytes, of the largest possible IP packet, including IP headers, layer 4 protocol headers, and layer 4 data, that can fit inside an Ethernet frame. While GCP VPC networks default to an MTU of 1460 bytes, it is recommended to configure your VPC Network MTU to a minimum of 1500 bytes. This setting is crucial because the MTU defined at the VPC Network level establishes the lowest supported MTU size forCisco Catalyst 8000V within that network.
To configure the MTU settings, see Maximum transmission unit.
