FCIP Link Down - Brocade 7800


I wonder if anyone can help. I'm planning a Firmware upgrade on a number of our 7800 SAN switches this weekend and noticed after checking the configuration today that one of the FCIP links is down.

We have 4 switches. 2 in one Fabric I call "STRETCHED_FABRIC_C" and two in another fabric I call "STRETCHED_FABRIC_D".

The first fabric is fine and up until recently the STRETCHED_FABRIC_D one has also been fine.

However today, there is no FCIP link:

The ge ports are showing online, but no speed indicated.

When I run:

hl-fcsw-slo-04:admin> portshow fciptunnel all

Unknown Error

hl-fcsw-slo-04:admin> portshow ipif all

Unknown Error

Error accessing IP interfaces on GE Port 0/all

There's nothing in the errdump output.

Has anyone come across anything like this before? Nothing has changed on the configuration recently.

Hi Spencer,

can you please perform the same commands from the corresponding site?



Kind Regards

Re: FCIP Link Down - Brocade 7800


The same commands on the other switch worked. Unfortunately, the only one I collected was:

portshow fcipcircuit all

Timeout on internal message. Please retry the command.

portshow fcipcircuit all


Tunnel Circuit  OpStatus Flags   Uptime   TxMBps  RxMBps ConnCnt CommRt  Met


  16    0 ge0     InProg  ----s    29d5h    0.00     0.00   24   40/40    1

  17    0 ge1     InProg  ----s  121d12h    0.00     0.00  16    40/40    0


Flags: circuit: s=sack

The one thing I did notice however was the the hl-fcsw-slo-04 switch had been up for 597 days, so I scheduled a reboot of the switch last night.

The reboot corrected the problem.

The firmware version of these two switches is: v6.3.1a

I don't know if this issue was a combination of the firmware and uptime - but I'm happy the reboot fixed the problem. I'm planning to upgrade to 6.4.2a as this is the current target code level suggested by EMC for our environment.

Before the upgrade I would keep an eye on the error counters for each of the GbE ports on the hl-fcsw-slo-04 switch. If there are excessive physical layer errors I would not upgrade until those are remediated. The upgrade process requires the circuits to go offline. When the upgrade is complete they will come back online.

Thanks for the advice. I double checked this side in the run up to the weekend work and it was all looking good.

The firmware upgrade went through over the weekend without any issues.
