Is there anybody know the bandwidth of OSC in 15530.

[justinfu]

As title: I have been asked by customer. And I did a show interface wave1/0 <--OSC card. and the outpurt is as below:

Wave1/0 is up, line protocol is up

Patched Interface(s) : Oscfilter0/0

Channel: 0 Frequency: 191.9 Thz Wavelength: 1562.23 nm

Signal quality : Good

Laser safety control : Off

Osc physical port : Yes

Wavelength capable for inband management: No

Threshold monitored for: None

CDL HEC error count: 3

Code violation and running disparity error count( 8b10b cvrd): 214

Last clearing of "show interface" counters never

Hardware is OSC_phy_port

Interface is unnumbered. Using address of Loopback0 (10.32.10.33)

MTU 1492 bytes, BW 10000000 Kbit, DLY 0 usec,

reliability 255/255, txload 1/255, rxload 1/255

Encapsulation SNAP, loopback not set

Last input 00:00:00, output never, output hang never

Last clearing of "show interface" counters never

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

5 minute input rate 2000 bits/sec, 2 packets/sec

5 minute output rate 3000 bits/sec, 2 packets/sec

3704817 packets input, 364542217 bytes, 0 no buffer

Received 0 broadcasts (0 IP multicast)

0 runts, 0 giants, 0 throttles

0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

3863706 packets output, 540967902 bytes, 0 underruns

0 output errors, 0 collisions, 0 interface resets

0 output buffer failures, 0 output buffers swapped out

It indicate that the bandwidth is 10G..is it possible? or is there anyone know the answer?

Thanks,

The bandwidth is 10Gbps since it is showing up in the show interface command.

As far as I know, the BW shown on the command is cosmetic and does not indicate the real "badnwidth".

The 15540 and 15530 OSC is GigE framed, but has a functional badwidth of approximately 2Mbps, a limit imposed by the CPU.

Thanks....

I found there is a doc said, the clocking of OSC is 1.25Gbps but it uses 2Mbps for Management....thanks for your answer for the advanced clarification.
