Configuring Promiscuous Mode
You can enable or disable promiscuous mode on a specific Gigabit Ethernet interface. By enabling the
promiscuous mode, the Gigabit Ethernet interface receives all the packets and the software then filters
and discards the packets that are not destined for that Gigabit Ethernet interface.
To configure the promiscuous mode using Fabric Manager, follow these steps:
Expand Switches > Interfaces > Gigabit Ethernet.
Step 1
You see the Gigabit Ethernet Configuration in the Information pane.
In the General tab, you can enable or disable the Promiscuous Mode option for a specific switch.

About VLANs for Gigabit Ethernet
Virtual LANs (VLANs) create multiple virtual Layer 2 networks over a physical LAN network. VLANs
provide traffic isolation, security, and broadcast control.
Gigabit Ethernet ports automatically recognize Ethernet frames with IEEE 802.1Q VLAN
encapsulation. If you need to have traffic from multiple VLANs terminated on one Gigabit Ethernet port,
configure subinterfaces—one for each VLAN.
Note If the IPS module or MPS-14/2 module is connected to a Cisco Ethernet switch, and you need to have
traffic from multiple VLANs coming to one IPS port, verify the following requirements on the Ethernet
switch:
- The Ethernet switch port connected to the IPS module or MPS-14/2 module is configured as a trunking
port.
- The encapsulation is set to 802.1Q and not ISL, which is the default.
Use the VLAN ID as a subscription to the Gigabit Ethernet interface name to create the subinterface
name (the
