Creating More than 64 Interfaces on a VS in VSX

Recently I have come across a requirement which needs to me create more than 64 VLANs in a VS. And i came across an error stating that VLANs cannot be created. That is when i stumbled across the SK99121.

The sk states that in order to achieve more than 64 interfaces in a VS, we need to change the Subnet Mask of the Internal Communication network from "255.255.252.0" to "255.255.248.0".

There is a statement in the sk - "To be able up to configure up to 128 interfaces, you should use a network address with 11 zeros in the end"

Can someone explain me the logic behind using a 21 bit Prefix length to achieve 128 interface and 22 Bit Prefix length to achieve 64 interfaces?

Hi,

It is required to extend the internal automatic member IPs allocated per Virtual System.
It is not done by default to minimize the network size.


Thanks,
