Verify the switch configuration has 802.1x authentication implemented for all access interfaces connecting to LAN outlets (i.e., RJ-45 wall plates) or devices not located in the telecom room, wiring closets, or equipment rooms. Static MAC Bypass or MAC RADIUS must be configured on access interfaces connected to devices that do not support an 802.1x supplicant. Junos supports three supplicant types: 'single-secure' (authenticate and permit only a single device), 'multiple' (separately authenticate and permit multiple devices), and 'single' (authenticate the first supplicant and permit all others).
Verify that the RADIUS server(s) are configured. RADIUS servers can be configured globally at [edit access radius-server] or defined for each group.
[edit access]
radius-server {
<RADIUS IPv4 or IPv6 address> secret "PSK"; ## SECRET-DATA
}
profile dot1x_radius {
authentication-order radius;
radius {
authentication-server <RADIUS IPv4 or IPv6 address>;
}
--or--
radius-server {
<RADIUS IPv4 or IPv6 address> secret "PSK"; ## SECRET-DATA
}
}
Verify 802.1x or MAC RADIUS is configured on all host-facing access interfaces when RADIUS is available as shown in the following example:
[edit protocols dot1x]
authenticator {
authentication-profile-name dot1x_radius;
interface {
ge-0/0/0.0 { <<< Connected device with 802.1x supplicant
supplicant single-secure;
}
ge-0/0/1.0 { <<< Connected device with 802.1x supplicant and interface support for MAC RADIUS
supplicant multiple;
mac-radius;
}
ge-0/0/2.0 { <<< Connected device without 802.1x supplicant
mac-radius {
restrict;
}
}
}
}
Note: Junos simultaneously supports both 802.1x and MAC RADIUS on the same access interface. To prevent 802.1x and have the interface use only MAC RADIUS, configure the "restrict" qualifier.
If RADIUS is unavailable or not configured:
[edit protocols]
dot1x {
authenticator {
static {
<MAC address>/48 {
vlan-assignment <vlan name>;
interface <interface name>.<logical unit>;
}
}
}
}
If the switch does not uniquely identify all network-connected endpoint devices before establishing any connection for access interfaces connecting to LAN outlets or devices not located in the telecom room, wiring closets, or equipment rooms, this is a finding.
