Figure 164: Configuring Global Settings for Network Access
Configuring
Network Access
for Ports
Use the Security > Network Access (Configure Interface) page to configure MAC
authentication on switch ports, including enabling address authentication, setting
the maximum MAC count, and enabling dynamic VLAN or dynamic QoS
assignments.
Parameters
These parameters are displayed:
◆ MAC Authentication
■
Status – Enables MAC authentication on a port. (Default: Disabled)
■
Intrusion – Sets the port response to a host MAC authentication failure to
either block access to the port or to pass traffic through. (Options: Block,
Pass; Default: Block)
■
Max MAC Count
6
– Sets the maximum number of MAC addresses that can
be authenticated on a port via MAC authentication; that is, the Network
Access process described in this section. (Range: 1-1024; Default: 1024)
◆ Network Access Max MAC Count
6
– Sets the maximum number of MAC
addresses that can be authenticated on a port interface via all forms of
authentication (including Network Access and IEEE 802.1X). (Range: 1-1024;
Default: 1024)
◆ Guest VLAN – Specifies the VLAN to be assigned to the port when 802.1X
Authentication or MAC authentication fails. (Range: 0-4094, where 0 means
disabled; Default: Disabled)
The VLAN must already be created and active (see “Configuring VLAN Groups”
on page 149 ). Also, when used with 802.1X authentication, intrusion action
must be set for “Guest VLAN” (see “Configuring Port Authenticator Settings for
802.1X” on page 302 ).
A port can only be assigned to the guest VLAN in case of failed authentication,
and switchport mode is set to Hybrid. (See
“Adding Static Members to VLANs”
on page 152 .)
6. The maximum number of MAC addresses per port is 1024, and the maximum number of
secure MAC addresses supported for the switch system is 1024. When the limit is
reached, all new MAC addresses are treated as authentication failures.
