5548 Core

‎10-05-2017 03:28 AM - edited ‎03-08-2019 12:16 PM

Good Day,

 

I have 1x 5548 nexus switch running as a core with layer 3 vlans running for the server farm, storage and other vlans, on this switch I have a trunk going to a 3850 switch where the servers are connected. The switches can see each other via cdp neighbors but cant ping each other.

 

from the core I can ping 10.10.50.2 which is the firewall interface, but cant ping anything else in this range, and this is the server farm range. On the nexus the layer 3 is configured as

ip vlan 50

ip address 10.10.50.1 255.255.255.0

 

on the serfer farm switch (3850) I cant ping, lease advise what I could be missing

Hiythis is just first glance but the trunk links dont match ,between core and access , one of them is specifiying vlan 10 as the native the other not , if your going to use a native use  it both ends or not at all

 

second thing i see is on access switch the vlan is not being forwarded so theres no l2 for that vlan in STP on the access side hence why reachabilitys not worting , why is the vlan being blocked because the L2 name is incorrect between the switches in the L2 DB

Names are case sensitive , correct this and the trunk

You said the issue was vlan 50 , that's vlan 1 your trying to ping which isn't even allowed on the trunk from what I see in last posts ?
as well that MGMT port is in a vrf an isolated table on the Core as its a nexus so you cant just ping like that it would need to be ping x.x.x.x vrf management but first the vlan needs to be allo0wed across the trunk between the 2

Same vlans should be allowed on the trunk each side , they should match exactly , some of the vlans are not on the 3850 side at layer 2 but that should not stop vlan 50 as its there but you should fix it by adding other vlans to the 3850

 

something else is blocking you pinging it , the arp is there and its complete , is there any fw , anti virus etc on the server software

 

what i would do is put a laptop on the 3850 put an ip address on it for vlan 50 turn off the firewalls , make sure its in the correct access port with vlan 50 set and see if the arp is in the vcore then try and ping it

 

You also need to set a default gateway for return traffic on the 3850

I'll check if there is any anti virus etc on the server software, and also add the other layer 2 vlans on the 3850. For the default gateway I'm not sure which ip address to put beause its seeing the core on 2 different ip addresses

What device will be doing the layer 3 intervlan routing ? you could point it at vlan 50 10.10.50.1 if the 5k is but if the FW is point it at that , I wouldn't point it at the mgmt. address 146 its in separate vrf table

the layer 3 vlans are on the nexus 5548, so I confoigured the default gateway to be 10.10.50.1 on the 3850, I'm still battling, I see a different server now on the arp table fixed its port setting to access vlan 50 but still
