Stores the currently active iptables rules to a file that will be applied upon reboot
Simple but useful command, I use this for purge an hard disk entry in Virtualbox registry file (is in ~user/.Virtualbox) that persist if I erase a Virtual Machine, so I need to delete it manually.
'no untag' is applied to _all_ ports under the default VLAN. Otherwise the default VLAN runs untagged over all physical ports. Pretty good idea to 'prune' your VLANs and define which ones pass over and across trunks that carry the default VLAN traffic.
This is how you make sure that ports in a VLAN remain, root ports. Typically, you would use this command on all your Core-1 switch VLAN ports, and then use 'rstp priority 1' on all your Core-2 switches. This is if you have a dual L3 core that is.
You need all those commands, in the sample output. I had some of this, but had to play, add remove, type random stuff like a monkey to finally get this working (clearly those IP's are fake to protect the guilty, and so is the key).
Although not frequently used, it is possible to clone an NTFS partition to an image file and, where necessary, restore the image to another partition. This command is useful, for example, if we want to keep a backup copy of our Windows installation, or in a corporate environment to install or repair a Windows of one or more computers. For the command syntax is refer to the documentation (man ntfsclone)
Okay, Jimmy, the command 'optical-monitor' is needed within the global config. for this command to work (and if supported by your licsense: yada yada, blah, blah). But, like its mad PHAT Kid, you dig? Basically, a Foundry/Brocade switch is reading the Laser light levels just like those Fiber test kits from Owl that cost 4k. I know, I also find it hard to contain myeself ;-) No really.....
