Because with the enable the feature fcoe, the Nexus will create the new service-policy, but not activate them: n5548(config)# system qos n5548(config)# service-policy type qos input fcoe-default-in-policy n5548(config)# service-policy type network-qos fcoe-default-nq-policy n5548(config)# service-policy type queuing input fcoe-default-in-policy n5548(config)# service-policy type queuing output fcoe-default-out-policy Is that correct? Thanks a lot Hi Scott,
I think on the Nexus 5548 and 5596 Plattform you also need to adjust QoS for FCoE. Because with the enable the feature fcoe, the Nexus will create the new service-policy, but not activate them:

n5548(config)# system qos
n5548(config)# service-policy type qos input fcoe-default-in-policy
n5548(config)# service-policy type network-qos fcoe-default-nq-policy
n5548(config)# service-policy type queuing input fcoe-default-in-policy
n5548(config)# service-policy type queuing output fcoe-default-out-policy

Is that correct?
Thanks a lot

I'm not too worried since ethernet doesn't really care at the end of the day that a frame is delivered either. You’re pretty much spot on with respect to VXLAN in UDP.

If you want to be able to use /usr/bin/unison to launch the GUI application, then undo the symlink and then use the longer path on the servercmd line in your profile. As for the SSH error, did you set up public key authentication to your host? That is a required prerequisite to making this work (note step #1 in the article). I don't go into details here, but there are plenty of other sites that describe how to make this work. Good luck!

Hi,

Guess this is what happens when you’re trying to hard fixing stuff at 1AM :-)

Anyway..

I symlinked as advised :

ls -l /usr/bin/unison
lrwxr-xr-x 1 root wheel 46 Feb 1 09:06 /usr/bin/unison -> /Applications/Unison.app/Contents/MacOS/Unison

Here’s my profile :

cat Library/Application\ Support/Unison/Unison\ \@\ Serveur.prf
root = /Users/x/UNISON
root = ssh://x@x//home/x/UNISON
servercmd = /usr/bin/unison
fastcheck = true
sortnewfirst = true
confirmbigdeletes = true
ignore = Name .FBCIndex
ignore = Name .FBCLockFolder
ignore = Name .Apple*
ignore = Name *.tmp

Still get this :

2012-02-01 09:11:20.442 Unison[2108:307] Connecting to Unison @ Serveur…
RSA host key for IP address ‘x.x.x.x’ not in list of known hosts.
bash: /usr/bin/unison: No such file or directory

If I try to run /usr/bin/unison manually :

$ /usr/bin/unison
2012-02-01 09:14:48.097 unison[2115:307] No Info.plist file in application bundle or no NSPrincipalClass in the Info.plist file, exiting

Odd..

You'll need to use the binary that's found inside the Unison application bundle. Depending on where you installed Unison, this would be something like /Applications/Utilities/Unsion.app/Contents/MacOS/Unison. Or, as I suggested in the article, you can symlink that long path to the shorter /usr/bin/unison and then use the shorter path with the servercmd option in the profile. Good luck!

I'm on OS 10.7.2 and have tried most version found on their website. I always end up with "Fatal error: Lost connection with the server" and this (GUI started from the CLI) : bash: /usr/bin/unison: No such file or directory $ ls -l /usr/bin/unison -rwxr-xr-x@ 1 root wheel 9344 Feb 1 00:02 /usr/bin/unison /usr/bin is first in my $PATH. I'm coming from the Linux world and find it absolutely stupid that you can run "Unison" or "unison" from the CLI and it will start the GUI no matter what. I must be missing something. Any hint would be greatly appreciated :-) Hi,

$ ls -l /usr/bin/unison

(teasing you) The MAC-in-IP encap is taking place in the hypervisor. You can move the L3 boundary down to the top-of-rack/access layer, so you dont need to worry about TRILL or FP...thats one of the biggest benefits of VxLAN. Think, McFly, think!
