Mastool version in Secondary node is showed as 0.0-0.0. The command to check mastool version in NetScaler is as below.
>shell
#cat /var/mastools/version.txt
0.0-0.0
We need to enable L3 mode in the primary node.
enable ns mode l3
Mastool version in Secondary node is showed as 0.0-0.0 because the secondary node was not able to reach NetScaler Console service.
The gateway to the NetScaler Console service was in the same subnet with SNIP(different subnet with NSIP). However, SNIP is passive in the secondary node and the secondary needs to forward the packets to the primary node in this situation. These packets' destination IP belongs to NetScaler Console service. service and the destination MAC address belongs to the primary node. In this situation , L3 mode must be enabled in the primary node to route these packets.
When L3 mode is not enabled in the primary node, the primary node will drop the packets sent by the secondary node.
