Isolated Networks
The isolated networks security feature can be enabled on a VLAN or a range of VLANs. Only standalone
mode is supported, as there is only a single LAG uplink.
When you enable this feature:
• Server-to-server communication is disabled on VLANs where the isolated networks feature is enabled.
• Servers on those VLANs can only communicate through the uplink LAG (core).
• The uplink core (ToR) applies all the required security measures and other services before switching or
routing traffic.
• The VLAN is configured only on the server-side interface specified as the isolated network. All traffic
arriving on this interface from the server is sent to the associated uplink.
• Multiple servers belonging to the same VLAN cannot communicate with each other over IOA because
all traffic is sent to the single uplink LAG and is not switched locally.
• For security, unknown unicast and multicast traffic received at the IOA uplink LAG is blocked towards
the server-side interfaces over VLANs that have the isolated network feature enabled.
The following illustration shows multiple servers (server M620A and server M620B) belonging to the same
VLAN (VLAN 5). For security, the servers cannot communicate with each other over IOA because all the
traffic is sent to the single uplink LAG (ToR) and is not switched locally. There is no switching between the
server ports.
