Brocade 6520 new ISLs not coming up

Hi svillardi2,

So the old ports show long distance off and isl r_rdy off, new ones have long distance LE and isl r_rdy off. Try setting the port to not long distance and see if you can enable QoS.

Hi Josh, and thank you for the assist!

No success yet.

The ports are almost the same now with a couple exceptions:

Port 48                                      Port 49
FC Speed Level: SOFT            FC Speed Level: 8G
Trunk Port ON                          Trunk Port OFF
E_Port Credits 40                     E_Port Credits OFF

The speed is set to 8G because I saw somewhere that all ISLs must match speed.
I can manually change the E_Port Credits to 40, however, I do not believe that they matter when bringing up the ISL, only the performance.

I do not know how to check for trunk port licenses.

licenseshow
X----------------------------------:
Second Ports on Demand license - additional 24 port upgrade license
Y----------------------------------:
Full Ports on Demand license - additional 48 port upgrade license

Here are the port configs (matched on all 4 ports -- 2 local, 2 remote)

showswitch - command not found

switchshow does not show anything related to port licensing.

Perhaps a different command?

Try switchshow. Page 1143 https://dell.to/35No95V

Page 516 https://dell.to/2UMjvPC may also help.

Does showswitch show which ports are licensed?

Confirming switchshow starts on 1113, not 1143.

yes, you are correct

Hi,

This is what fixed it:

Portcfglongdistance 53 LE 1

Portcfgislmode 53 1

Portcfgspeed 53 0

Thanks for your help.  We needed a vendor to figure it out.
