- The IP route is configured correctly.
- The IP host has a route to get to the Gigabit Ethernet interface subnet.
- The Gigabit Ethernet interface is in the up state.
Use the ping command to verify the Gigabit Ethernet connectivity (see
command sends echo request packets out to a remote device at an IP address that you specify (see the
"Using the ping and ping ipv6 Commands" section on page
Use the show interface gigabitethernet command to verify if the Gigabit Ethernet interface is up.

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
