SUN Server issues with C4507R-E

nedian123 · ‎01-30-2010

Hi,

Has someone experienced loss of traffic on Layer-2 b/w SUN Solaris 8 Servers. Both the servers are in single Vlan. File transfer is having breaks. There are no errors on switch interfaces. SUN Server NICs are GiG & I have verified on switch & found that there are no duplexing or speed issues.

We have tried connecting them to other ports on the same switch but problem persists.

Can we suspect this might be because of Interoperability issues like flow control.....SUN Server NIC settings are attached.

Hello Aktar,

post a sh interface gix/y of interfaces connected to SUN servers

or look for

input and output pause frames counters these could lead to flow control action.

Also it is important to verify what linecards the ports belong to?

you can check this with

sh module

older linecards are highly oversubscribed they provide 6 Gbps per slot so for 48 GE linecards 8 ports share 1 Gbps ASIC resources.

new linecards with final E are able to connect at 24 Gbps per slot

Hope to help

Following is output. Module is WS-X4648-RJ45V-E. I can't see any pause frames as well.

Hi Akhtar,

Kindly clarify is the sun server is having dual nic connectivity with switch,If yes then check the teaming configuartion of nic at sun server end.If it Active/Active configuration then change that to Active/Passive configuration and then check the ftp between the server.

and also check the ftp space issue in destination directory while uploading or downloading.

Hope to help
