164 Setting Basic Network Information
Static IP subnets on inband ports (configured on switch VLANs) may not
overlap with the OOB port subnet. If configuring management access on the
front-panel ports, it is recomended that:
• A VLAN other than the default VLAN be used to avoid attack vectors
enabled by incorrect cabling.
• Both ACLs and Management ACLs be utilized to reduce the possibility of
DoS attacks or intruders gaining access to the switch management
console. The advantage of the management ACL is that it can also protect
the OOB port, whereas ACLs can only protect access via an in-band port.
