INterface VLAN

[sachinc01]

Hi Team,

I have configure some VLAN on my switch with interface VLAN IP ...

If some one person USE VLAN INTERFACE IP to his machine then totally switch work is stop.

Can some one give idea how to avoid this type of issue.

Which   configuration is need on the switch to avoid this issue.

If some one person USE VLAN INTERFACE IP to his machine then totally switch work is stop.

The vlan ip address should be removed from the DHCP pool , the user should not be able to receive the same IP address of the Vlan interface , and if its static well thats a user issue , the switch cant prevent user error like that , lock them out of there TCP/IP settings or put them on DHCP and control it

Adding to @Mark Malone, you can further secure your access-layer with DHCP Snooping and DAI which will prevent users from using IP addresses which have not be received from trusted DHCP servers.

cheers,
