has anyone faced this problem with dhcp snooping .
here;s my scenario
sw1 has a host on vlan 10 and there;s a SVI for vlan 1o with ip add
10.1.1.1/24.
dhcp server is configured on the switch
ip dhcp excluded-address 10.1.1.1
ip dhcp pool mypool
network 10.1.1.0 /24
default-router 10.1.1.1
the host on SW1 gets the ip address from dhcp server.
i have also enabled dhcp snooping for vlan 10.
i have a SW2 with a SVI for vlan 10.whose ip address is set to get from
dhcp
int vlan 10
ip address dhcp.
trunk has been configured between SW1 and SW2.
i have also enabled dhcp snooping for vlan 10 on SW2.
and i have configured the trunk ports on both the switches as trusted ports
for dhcp snooping.
on SW1 i can see the dhcp server has assigned a ip address to the SVI on SW2
but on SW2 the ip address is not assigned to int vlan 10.
with the debug i see that when the dhcp reply reaches the trunk port of SW2
it says it cannot find the mac-address and drops the packet.
in the mac-address able also i cannot the mac-address of the SVI vlan 10.
when i disable dhcp snooping everything works fine, the SVI on SW2 gets the
ip address from the dhcp server.,
can u help me with getting this working with dhcp snooping or tell me why
this is not working .
any help will be greatly appreciated.
regards
sebastan
