5548 Core

[Pumpi]

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

[Pumpi]

I gave myself an ip in the vlan 50 range 10.10.50.10 and set the dfgw to .1 connected to port gi1/0/48 on the switch, on my laptop I can ping the gateway but on the switch I cant ping my laptop

10.10.50.5 is one of the servers connected on the 3850 on port gi1/0/2, I still cant ping it on the core even though its on the arp table.

Thats purely layer 2 so the 5k cant do the routing currently between intervlans

In order for me to turn it on, I would need the licence key from the ISP from which the switch was bought, if it was bought right?

[Mark Malone]

yes exactly the PAK itself or the actual license file so it can be added to the 5k then it will need a reboot when added and should go yes status

[Pumpi]

Hi Mark,

Thank you for your assistance, much appreciated.
