Table 10: Fiber Port LEDs
Description State LED
Link is present. Glows green LINK ACT
Activity. Flashes green
No link present. Off
Connection is 100 Mbps. Green LINK SPD
Connection is 1 Gbps. Yellow
Connection is 10 Gbps. Orange
If LINK ACT is on, the connection is 10 Mbps. If LINK ACT is
off, LINK SPD off indicates no link is present as well. Off
Interface is not in bypass mode. Green BYP
Interface is in bypass mode. Yellow
Interface is turned off (NICs off state). Off
NOTE: For fiber interface ports, if failure or shutdown triggers NICs off state,
LINK ACT and LINK SPD LEDs remain lit.
Traffic Interface Features
Traffic interfaces are network interface cards (NICs). In the IDP Series configuration
abstraction, a pair of traffic interfaces is called a virtual router. For example, virtual router
vr1 comprises interface ports eth2 and eth3. For each virtual router, you use the Appliance
Configuration Manager (ACM) to configure the deployment mode (sniffer or transparent)
and bypass options (internal, external, or off). You also configure a global setting (affects
traffic flow through all interfaces) on how to handle Layer 2 packets. The following topics
describe these settings:
• Deployment Mode on page 10
• Layer 2 Bypass on page 10
• Internal Bypass on page 10
• External Bypass on page 12
For guidance on using ACM to configure virtual router settings, see the ACM online help.
