• Management VLAN: ID of a configured VLAN (1–4094) through which you can

However, if the management VLAN is changed, the management station must
be attached to a port that belongs to this VLAN.

messages from this switch. Traps indicating status changes are issued by the
switch to specified trap managers. You must specify trap managers so that key
events are reported by this switch to your management station.
• SNMP Read Community: A community string that acts like a password and
permits access to the SNMP database on this switch. Authorized management
stations are only able to retrieve MIB objects.

4.1.2 Ports
Port Security ensures access to a switch port based on MAC address. This limits
the total number of devices that use a switch port and protects against MAC
flooding attacks.
