Config setup of DCX 10Gb ISL to Cisco ONS (pass-through mode)

Existing config is McData 6140 with 10Gb port to Cisco ONS dark fibre across 20miles to remote Cisco ONS to McData 6140.

Cisco is pass-through, meaning no spoofing r-rdy.  It works fine.   Now replacing 6140s with DCX (v7.0.1).

Trying to move ONS connection to DCXs at local and remote site on DCX 10Gbs port (FC16-32) port 1/0.

Unplug cable from 6140, move to DCX port.  Connection will not come-up.  DCX seeing no light.

SFPs are 1310nm in 6140 and DCX.   But if you move the cable back to 6140 at each end the McData ISLs

come up. (Last Brocade guide on SAN Distance Extension (that I found) is year 2007.)

Cisco support states it's a Brocade layer2 config type issue since same connection pairing works on 6140.

Per Cisco, the reason the DCX records no light is because ONS turns-off laser after X amount of time due

to failed link bring-up.  (Trying to get fabriclog, portlogdump, RASlog for further details.)

Checked portcfgshow.  Found FEC enabled, disabled it (per release notes) on each end.  Portdisable/enable, no change.

QoS disabled and VC_link_init disabled too  but no help.   Port is G-port hard-set, so should allow for fc1/0 to become E-port.

Anyone have a working Brocade DCX 10Gb port configuration via Cisco ONS in pass-thru mode?  If so, please post the

portcfgshow.

I'm not experienced whit FC16-xx Blade, however 10G SFP+ are required for 10G connection.

have you such SFP+ inserted in the Blade ?

In Brocade Matrix ( generally brocade not longer support Cisco ) is any such CISCO ONS not listed.

Have a look to this Thread here.
