Cisco 3750 v2 Cant ping connected devices

[johannesmoolman7574]

Good day I need some assistance 

i have added additional CCTV cameras onto a switch but are unable to ping any of them, from my computer and not even from the CLI.

My network is working otherwise, i can ping cameras on that same vlan that is connected on another switch.

all my switches goes to the control room that is a 9300 all vlans etc has been setup. i have even replaced the switch still nothing. i have done the same setup i have done on all my other switches but it just refuses to see the Cameras.

any help would be great

do you run 
ip routing 
in cat9000 ?

[johannesmoolman7574]

Hi Yes i am running ip routing on the main 9300 cisco where all my switches connect to

[MHM Cisco World]

only check VLAN of Camera in each SW toward the Core SW. 
I think VLAN is not add to SW or not allow in trunk toward Core SW.

[johannesmoolman7574]

What stumps me is that the switch can ping the core switch and all other vlans and devices on all other vlans. just not the physical devices plugged into it. 

[MHM Cisco World]

if the switch use VLAN SVI different than Host VLAN SVI then the frame must go up to Core, there in Core inter-VLAN will done. 

so there are two path we must check 
can ping from SW VLAN SVI to the VLAN SVI of SW  in Core ?
can ping from Host to VLAN SVI of host in Core ?

Is the camera VLAN extended over the trunk to the core/control room?

show span root
show span vlan XX detail
show int trunk

Is your laptop on the same VLAN and switch as the cameras when you try to ping and configured in the same subnet?

Sounds like a VLAN problem, esp if you already replaced the switch.

Ok so that is the output of show span root and clearly that is not right. i have checked my other switches and all their Vlans got a assigned root span.

how do i fix this ?

[MHM Cisco World]

I think change the spanning tree vlan1 priority make it higher than Root of other VLAN fix issue. 
do this in SW CCTV connect on

[johannesmoolman7574]

show span root

This is the config of my other switch show span root. each vlan is designated a port and is working 100%

show spanning tree vlan 1 
show spanning tree vlan 10

I did it for vlan 1 and 30 . Vlan 30 is the one giving me headaches.

[MHM Cisco World]

This bridge is the root <<- this is why there is no interface with other vlan 
the STP mode is IEEE " Spanning tree enabled protocol ieee" and I think the other SW using different Rapid PVST or MST. 
can you check what is mode of STP using in other SW??

[johannesmoolman7574]

The other switches is on Rstp i have set this one to Rstp as well still not working

[MHM Cisco World]

I inform you before to check the VLAN and allow vlan in trunk in the way to root bridge, 
anyway 
this lab give me exact same issue you have 
VLAN1 show interface to root bridge 
other vlan don show interface!!!
Yes, how I get this reuslt ?
from IOU1 to IOU2 there is trunk and vlan allowed in this trunk BUT from IOU2 to IOU3 (root) there is access assign to vlan 1. 
here 
IOU1  not receive any BPDU about other vlan only VLAN1 from root bridge and hence you can see that IOU1 elect interface and IOU3 as root bridge 
but what about other VLAN ?
other VLAN since IOU1 not recieve BPDU it declare that it is the Root and hence you dont see root interface.

you issue is vlan missing in one SW OR not allow in trunk and hence there is no BPDU.
