S4128T-ON - OS 10.5.4.0
Hello,
we deployed new switches 2x S4128T-ON in VLT domain instead of old stacked Dell Powerconnect 6224, 3.0.0.8.
The thing is, now Windows NLB cluster IP isn't reachable anymore. Cluster is in VLAN 300, so I configured VLAN 300 with command: nlb-cluster "ip address" "mac address" interface port-channel20 (uplink to the switch with servers connected to it). After this command, Cluster IP is reachable in VLAN 300, but not from other VLANs. After some troubleshooting, packets are somehow dropped on new switches S4128T-ON.
NLB IP is multicast.
Please help, I want the cluster IP to be reacheable from other VLANs too. All VLANs are finished on Sonicwall.
I wanted that same command, as I used for VLAN 300, to be used on other VLANs, but switch says that NLB cluster is already configured.
On old switches, there was was never any multicast features or static ARP records configured.
Regards

Hello,
I don't see any clear error on the configuration.
To deep dive in the troubleshooting you have to open a ticket from our technical support in order to escalate to an L2 support.
Is it possible to do that for you?
Thanks
