SA540 DHCP server multi subnet ISSUE

i have SGE2000 is Core Switch it have 3 vlan

vlan 1 :

vlan 2 :

vlan 3 :

static route / 24 next hop


vlan1 :

static route : next hop

its connect with SA540 in ports 1st no vlan enable i config only static route back to core switch. now i want to use SA540 to assign IP for clients in every vlan it can.

i see vlan function and i enable and create vlan same the SGE2000 and create DHCP scope and disable Inter-vlan routing because i want to use routing cross vlan on SGE2000 , then clients on every can't access to vlan 1 but when i delete vlan on SA540 it ok , clients can access to vlan and can use internet.

have solution for this because i don't have dhcp server and in AP have multiple ssid , i think it must use dhcp because i can't fix ip for wifi clients

thank you for your support.

Re: SA540 DHCP server multi subnet ISSUE


Based on your decription and configuration, I am suspecting there might be a routing loop.  Can you remove the static routes and disable the inter-vlan function in the SA to see if you still encounter the same issue?

If issue persists, can you PM your SA and your switch confguration?
