Hi i do it in ci to be sure get in wipe everything   in cli # mode when you login   type erase startup-config then type reload and hit return do not save it , this will wipe all configurations   then go back in and go to flash check it with either show flash: or dir flash:   it will bring up all the listed files stored, here delete one by one except the ios software itself make sure to delete flash:vlan.dat which contains all vlan information and doesn't get wiped on the   you could do that first then erase startup command last either way just make sure you get everything   This will wipe the switch to factory , everything should go from flash except the .bin file which is the software   This is how you  would connect to a Cisco switch from pc   https://www.youtube.com/watch?v=7sM4f1_QloQ   Any questions just ask   ...

HI sounds like a bug but i don't see a specific match in your release notes below for 6.2.14 , good few SVI bugs but nothing identical , do you have support to open a TAC on this ? There is a more recommended image for that platform 6.2.16 as well https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/6_x/nx-os/release/notes/62_nx-os_release_note.html ... View more

This is what im talking about has an example too you could base your config off http://blog.ine.com/tag/llq/   edit: when your looking at that example in your case the policy map would be applied to your wan interface so it can honor traffic going out ... View more

Hi thats layer 2 qos , you should use llq/cbwfq qos for the wan circuits class-maps and polcy applied to wan interface , that config above is actually 2 types of qos , auto qos and mls qos , you would usually only use 1 type ,also priority-queue out will make sure all voip packets are serviced first in that before anything else can cause starvation of other queues if not careful in MLS , if using layer 2 qos with cisco phones i would just set mls qos trust dscp as the phones mark with EF DSCP at source and priorities then honor it in class-map with priority command so its carried through wan at bottleneck ...

Hi then you should use source vlan to capture everything on that vlan , you can set a range of vlans and then also set one of them to be excluded using filter but you dont want that if you want to capture all vlan 100 traffic ... View more

no your good only 1 ip but you need to have both 2k access ports in correct vlan of the mgmt subnet range. ... View more

Hi No it wont all my stacks are set like that i have them split across multiple out of band management switches , only one of them can be active at a time and its the master mgmt port only , if that fails completely secondary mgmt will take over and become active its better to use a dedicated mgmt switch for oob though rather than a fex connected to a 5k , that means your mgmt traffic will be pushed up through the cluster and mix with prod traffic which negates the whole out of band port really ...

also the wan is where the bottle neck is usually too so if anywhere that's where you should think about adding the actual class/policy map at least for voice anyway , you could just match the voice subnet and make sure its set as EF , you dont want that getting delayed or impeded ... View more

So the MLS is trusting COS, so as example phone will mark at source COS5 then MLS will re-map it back to DSCP 46 for priority queuing mls qos map cos-dscp 0 8 16 26 32 46 48 56 Cos 1 2 3 4 5 you could as an option just set the port to mls qos trust dscp that way it doesn't have to re-map while passing through the switch , set the same on the up link , any values that are set by source device are then trusted by dscp right way through but as its set now it should work fine its better that class map us not in use anyway as its setting voice to a lower priority which could cause you issues ...

Hi you actually have 2 forms of layer 2 qos in operation there you only need 1   your running both auto qos and mls qos on same switch , you should pick one   The auto qos is seperate to mls  , mls creates it own global mls maps too in queues , policy map only gets applied in ios-xe with auto qos on ios you just need get the auto qos under the interface   with priority queue out all that queues gets serviced first before anything else , all critical traffic thats  is not in play if its not in dumped into it   the class map you provided is not in use if not applied priority-queue out mls qos trust device cisco-phone mls qos trust cos auto qos voip cisco-phone   part 1 and 2 of this doc explain MLS very well how it works on switch http://www.davidsudjiman.info/2012/02/14/cisco-3560-mls-qos-part-1/ ...

it could be a firmware bug too so if you dont get a concrete answer i would take a chance and upgrade the firmware if nothing has changed in your end to cause this ... View more

Hi maybe a solution in this thread looks similar to your alert you could try that see if it works There is also a specific SMB section for these switches on this forum you may get a better response on https://supportforums.cisco.com/t5/lan-switching-and-routing/problem-with-sg300-28p/td-p/2587171 ...
