Security VLANs
Security VLAN’s allow for limiting telnet, SNMP and web access to the switch to a specific VLAN. The VID of the Security VLAN may be changed from 255 to another value after creating the VLAN. The new VID must not already exist on the box.
Note: Before enabling the security VLAN feature, you must set the management port you are managing from to PVID 255. This is due to the fact that the CPU can only accept management requests from VLAN 255, this is intentional and part of the feature of Security VLAN.
