Hi,

I have 2 N1524P switches that I wish to trunk together , each of these switches also connect to our core. The problem is that as soon as I activate the trunk between the 2 switches one will fail to respond , no ping etc. What is the probelm ?, config below

Switch 1

interface te1/0/3

description To Core

switchport mode trunk

switchport trunk native vlan 666

switchport trunk allowed vlan 100,119-122

no spanningtree portfast

-------------------------------------------------------

ip route 0.0.0.0 0.0.0.0 10.50.48.1

-------------------------------------------------------

interface vlan 100

description Device_Management

ip address 10.50.48.100 255.255.255.0

-------------------------------------------------------

interface te1/0/4

description To Other N1524P

switchport mode trunk

switchport trunk allowed vlan all

no spanningtree portfast

-------------------------------------------------------

The same on the other N1524 except the management ip address increments by 1,
