Cant access my management VLAN address of my switch

[hshabany]

We have purchased a Cisco 3650 switch. The switch is working fine and I can access it through an IP address in the default VLAN but I am unable to access it through out management VLAN (254). I have 4 other Cisco 3560 switches that I can access just fine through 254 VLAN. I have allowed the 254 VLAN in the trunk but that didn't help. I am not sure what I am missing here.

Hello,

what is the difference between the working switches and this one ? Which template are you running (sh sdm prefer) ?

[hshabany]

other than switch model, I cant see any differences. As for the running template, it is the desktop default template for older switches and the advanced (low scale) template for the new one.

Perhaps changing the default gateway of the switch to appropriate host on VLAN1 and not that of VLAN254 may have something to do with it.

[hshabany]

the default gateway is handled to route traffic from both VLANs

Hello

ip routing

ip route 0.0.0.0 0.0.0.0 10.80.254.1

Paul,

I've tried that but still not accessible through management VLAN.

[paul driver]

Hello

apologies that wasn’t you core  switch was it? 

Can you post your core switch config and remove the ip routing I asked you to apply on that access switch 

[hshabany]

no worries, I have deleted the route and attached configuration of core switch.

[paul driver]

Hello

Can you ping 10.80.254.5 fro the core?

Also looks like you have enable QinQ tunneling on sw5 -  do you need it?

Paul,

cannot ping 10.80.254.8 from core switch. I have enabled QinQ tunneling because I thought that I might need it for communication between 2 different model switches.

[paul driver]

Hello

Can you remove it and just create a normal trunk between core and L3 switch, then test again.

[hshabany]

Paul,

I've already tried it with a normal trunk with the same result.

[paul driver]

Hello

I suspect one of the l3 interfaces are not active on one or both of the switches., can you post -
sh ip int brief | in Vlan

Also make sure the respective l2 vlans are created on each switch.

Adding @paul driver suggested,  can you also post out of below command.
