Hi,
Hardware is X450G2, Firmware 22.4.1.4.
I´d like to configure "ip-security dhcp-snooping" on Layer2 Access Switch for a few VLANs. How to configure Uplink Ports to Layer3 Core Switch where VLAN IP Interface resides ?
For example, if 1:28 ist the interswitch link between Access and Core (Uplink), do I only have to configure
"configure trusted-ports 1:28 trust-for dhcp-server"
and that´s it for all VLANs ?
Or is it necessary to configure additionally
"enable ip-security dhcp-snooping vlan VLAN10 port 1:28 violation-action none"
"enable ip-security dhcp-snooping vlan VLAN11 port 1:28 violation-action none"
"enable ip-security dhcp-snooping vlan VLAN15 port 1:28 violation-action none"
for every vlan where DHCP Snooping is enabled ?
I´m asking due to https://extremeportal.force.com/ExtrArticleDetail?an=000080865
NOTE: Please ensure that ip-security dhcp-snooping is enabled on the port where the DHCP traffic is expected to ingress / egress the switch and ensure that the violation-action is set to none
Thanks,
Marcus
