[f-nsp] TurboIron 24x throughput issues.

[Arjan Van Der Oest]

FIrst of all, one side of the LR receives much less signal. This can be an indication there is something physically wrong with your fiber. Have you checked the interfaces for input/crc errors (show int ether 1)?

Also, what does  a 'show cpu' and 'show cpu lp' show during the data transfer?

Hi,

I have two TurboIron 24x switches which are connected together by 10G (10G-SFPP-LR) Single Mode Fiber on port 1 of each switch.

Port  Temperature   Tx Power     Rx Power     Tx Bias Current
+----+-----------+----------+------------+-------------------+
1   28.4960 C  -001.2813 dBm -006.8068 dBm   34.518 mA
       Normal       Normal        Normal      Normal

Port  Temperature   Tx Power     Rx Power     Tx Bias Current
+----+-----------+----------+------------+-------------------+
1   29.4804 C  -001.6146 dBm -003.0504 dBm   38.234 mA
       Normal       Normal        Normal      Normal

I have this VLAN setup on both sides of the connection:

vlan 2500 by port
tagged ethe 1
untagged ethe 25

On each switch I have a server connected at 1Gbps / copper on port 25.

When I use iperf to test throughput I am only able to get about 40Mbps in both directions, when I use wget to copy an iso file between them I am only able to get 5M/sec which is about 40Mbps.

It seems like no matter what I do I can't resolve this issue.

Does anyone have any clue what could be going on?

thanks,
-Drew
