4.1 Sensors and Fiber Question

emusican

On a 4250XL sensor, assuming both fiber interfaces (int2 and int3) are being used....is there a way to show their status in the linux interface not the CLI?

In other words, I want to know if there is an "ifconfig" equivalent but for the falcon interfaces.

ifconfig -a will respond with the follwoing

ge2_0 Link encap:Ethernet HWaddr 00:00:00:00:00:00

BROADCAST MULTICAST MTU:1500 Metric:1

RX packets:1 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

Interrupt:20 Memory:f0180000-0

ge2_1 Link encap:Ethernet HWaddr 00:00:00:00:00:00

BROADCAST MULTICAST MTU:1500 Metric:1

RX packets:56208 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:4098648 (3.9 MiB) TX bytes:0 (0.0 B)

Interrupt:20 Memory:f0180000-0

I do not see a particular status message. You might try doing a ifconfig -a more than once and comparing RX bytes.

Hmm I do not get anything returned for the fiber card when I do an ifconfig -a when logged in with the service account. When I connect to the device using the browser and look at the interfaces I see eth0, eth1, falcon1 and falcon2. I'm trying to do a tcpdump on what is defined as int2 from the CLI which is falcon1. Thoughts, hints or ideas are appreciated. I currently have a cisco case open asking them how to run tcpdump on the fiber interface as well.

I found out later that in order to do a tcpdump on a fiber interface on these 4.1 sensors, you have to stop the cids service, and use the falcondump tool.

From what I hear, in the next sensor version, due out soon, you will be able to tcpdump on those fiber interfaces as normal without stopping the cids service, and they should show up in ifconfig.

For now however, we are stuck going into the CLI and doing a show interface sensing, which is the only to see if these interfaces are up.
